They are here to help. Like I said in the other thread, order some JJ84's... put them in yourself... likely be the end of your problems w/o a trip to the tech. Sovteks never lasted that long in my AC30. I guess you could try the EH or those new Mullard's... And the other thing here... is that the AC30 you and I own is a totally different beast then the newer Chinese custom classics.

Not even remotely the same amp. Would you call an electrician to change your lightbulbs? A 6 hole AC-30 runs (of memory serves me) 5 12AX7's, 1 12AU7 a quad of EL84's and a GZ34... Personally Im not fond of JJ tubes much at all...if it were mine since I wouldn't want to drop 5 bills on NOS Mullards I'd see if I could get my hands on some NOS Telsa EL84's...these are not JJ tubes and are much higher quality in terms of construction as well as tone IMO.

If you want new EL84's i'd suggest the reissue Mullards. For preamp tubes, Im a big fan of the Tung Sol reissue 12AX7's for current production since NOS 12AX7's are so much money these days...for the 12AU7 high quality NOS 12AU7's can be had for $15 and less but EH is also making a really good new 12AU7.

Last id your GZ34...if the one in the amp works leave it...rectifier tubes work or they don't work, if it works don't bother however a lot of those "reissue" Korg era AC30's has SS plug in rectifiers and those should be pulled out and thrown away...they cause the amp to sound terrible not to mention run too hard.

If you need a GZ34 DO NOT TRY TO CUT COST on them...Spend the money, get a good one and be done with it. If you HAVE to buy current production the new Sovtek is pretty good (I actually use of them in my Deluxe). Personally Im not fond of JJ tubes much at all...if it were mine since I wouldn't want to drop 5 bills on NOS Mullards I'd see if I could get my hands on some NOS Telsa EL84's...these are not JJ tubes and are much higher quality in terms of construction as well as tone IMO.

If you want new EL84's i'd suggest the reissue Mullards. With the way the AC30 eats tubes I wouldn't spend the bucks on NOS myself... How's the reliability with the new Mullards? Sensitivity to vibration? That was my problem with Sovteks... they couldn't handle the stress of the amp. And tubes that work in other amps don't always work in an AC30... The JJ's IMO are a nice trade-off between tone & durability. What good is a tube that sounds better but fails? I might try the EH next time out...

just for something different. the New Sensor (reissue) Mullards use the same larger, heavier bottle as the Sovtek. The Sovtek EL84s are usually really durable in my experience, just not that great in the tone dept. The Mullards sound good to my ears (for new production tubes) - a little dark, nice breakup. If you want to get maximum Vox "chime" I'd go with the Ei EL84s.

I've used a couple sets from Dougs Tubes now and reliability has not been a problem. Noise is average. Midrange detail blows the JJ out of the water. Just have to make sure they're burned in and tested by the vendor. lots of bad tubes per batch since QC at the factory was so low. I would not just randomly buy Ei tubes from someone online or on EvilBay. if it matters, the Ei EL84s used to be OEM in the AC30s . . . I would if the socket carried several hundred volts! In all reality there's a much higher chance of getting electrocuted while changing a lightbulb or plugging in a toaster oven then you do while changing a tube!

CLF - Do the Mullard 84's share the same plate structure as the Sovteks? That's the fault of those tubes... not the glass. They're somewhat prone to noise from vibration and the AC30's are so rough in that regard... not to mention the extreme heat. When I tried the Sovteks in my AC30 & they misbehaved I put them into my pro jr and they were fine. There's actually two different Sovteks, a standard EL84 and an EL84M which is supposedly more durable.

I haven't tried those... are the Mullards coming out of the same factory?! I have no idea... FWIW - I'm not sure there's a source for Ei power tubes at this point unless someone has old stock. They'd be great if you could get 'em... and get ones that weren't somewhat shaky. That's what I swore by until the factory went south...

That's what I swore by until the factory went south... I don't have the old Sovteks that came OEM in my Laney to compare plate structure unfortunately. I believe that the Mullards are made with the same tooling as the EH though with a few minor changes - definitely different from the Sovtek EL84 and EL84M. The M is designed to handle higher plate voltages but that's all I know. The M's don't have a reputation for good tone but I can't attest to that personally.

To my knowledge, all of the New Sensor brands are still made at the Reflektor factory in Russia but there different machines are used for different tubes within that factory. As far as the Ei, you're right that the factory is not currently producing tubes. anything you buy now is technically NOS A few vendors still have a decent stock. I have only purchased them from DougsTubes and he does a great job at filtering out the bad ones. they're not expensive either. surprisingly, Mike @ KCA NOS Tubes doesn't have the Ei listed right now.

he usually has everything. Keith, one other tube that might be worth trying is the newer TAD EL84-STR. It's supposed to have the durability of the EL84M with better tone. they're priced about average for an EL84 - $60 for a quad.

Vox AC30 Overview The Vox AC30™ has been around since 1960. It is one of the classic most recognisable British amps to this day. It sounds absolutely gorgeous and I bitterly regret over and over again selling my 1960’s one. Here is a quick look at the different models and my recommendation on the two best versions to buy.

The Vox AC30 users include , The Shadows, The Beatles, Rory Gallagher, Brian May ( Queen) . Quite a diverse set of music styles which reinforces this amp’s versatility and enduring qualities. You can still buy A new Vox AC30 today so the same amp has been in production for 55 years ! It will soon be heading for its pension. But is it the same amp?

The big answer is no. There are solid state, semiconductor based versions and I only going to look at the “real AC30’s” and by that I mean the valve ones. I have been looking at all the schematics since 1960 and so far there are ten different valve line-ups in these amps, so clearly there have been a lot of changes along the way. A good source for all the Vox AC 30 vintage amp schematics is Vox themselves and you can have a look by clicking .

They have done an excellent job of collating all the info. The Vox AC30 was designed and made original by JMI (Jennings Musical Industries). Eventually, a big UK music distributor called Dallas Arbiter ( they used to be the Fender importer until Fender set up their UK operation) bought out the rights and starting making a few amps, and then Korg bought out the rights.

Kong being a leading Japanese keyboard maker, no had a UK product line so has a challenge manufacturing the amps. Marshall came to the rescue. At the start of Korg production Marshall built the VOX amps.

Sounds like heresy but it made good business sense. Outside of the UK, Marshall products were distributed by Korg so there already was a close business relationship.

I don’t believe any of the Vox products are made today by Marshall perhaps excepting the hand wired AC30’s. Every valve Vox AC30 ever made has four EL84’s. Back in 1960 this was a common cheap valve found in record players. Usually only one so using four enabled the output power to be quoted as 30 watts. Replacement Valve Kits We have made complete replacement valve kits for these Vox AC 30 versions and there is a link in the time line below for each kit.

Where required the GZ34 is included. The EL84’s are all matched and there is one matched ECC83S for the phase splitter position. Our Supermatch valves come with test certificates. all valves are fully tested.

we have tried to date the models and this for production. Keep in mind that a model made in 1985 could have bought by a customer in 1986. Before ordering a good rough check is to count the number of valves in your particular model. On our home page if you use the search by make and model, all of these variants are listed and you will see the valve kit that is available kits.

A Brief History and Timeline of the Vox AC30 Here is a quick history of the valve line-ups ( excluding the EL84’s as they are in every one of these amp models). The list below shows the pre-amp and rectifier line up. 1960 : Introduced : GZ34 rectifier, one ECC82, 4x ECC83, 1961 AC30 Top Boost : 5 x ECC83, 1x ECC82, 1 x GZ34 ( the extras ECC83 adding the boost) 1964 : AC30 Bass : same line up as the 1960 amp 1 970’s : Dallas Arbiter AC30 Top Boost : 4x ECC83, 1x ECC82.

No GZ34 as it was replaced by 4 diodes. This model was in my mind a cost cutting exercise and a step backwards. 1978 : AC30 Top Boost : 6x ECC83, 1xECC82 . No GZ34. I guess they added the two ECC83’s to get the gain up 1986 : AC30 Top Boost. 1x ECC82, 5x ECC83 1990 : AC30 Limited Edition 1x ECC81, 1x ECC82, 4x ECC83 1991/2 : Ac30 Vintage Model with no reverb : 1x ECC81, 1x ECC82, 4x ECC83 1993 onward : AC30 Top Boost Re-issue : 1x ECC82, 5x ECC83, 1x GZ34. The valve rectifier made a return at this point because the diodes in the power supply removed the compression effect of the good old valve rectifiers In the 2000’s : AC 30 C1, C2, C2X.

This is the solid state/ valve hybrid . No GZ 34 , using solid state rectifiers and 3x ECC83. The CCX models at least have the Gz34 rectifier Today : AC 30 CC1, CC2, CC2X : 3x ECC83.

1x GZ34. There are far fewer valves in these models as a lot of circuitry is now in semiconductor technology. The ECC82 was always used in the vibrato circuitry and this has gone in favour of solid state circuity. Vox Website The Vox website which shows all their current amps is at My Conclusion So if you want rectifier compression, with the total valve sound and a good high gain amp you can see why the 1960’s top boost amps are so highly sought after.

The prices are high due to their sheer quality of sound. For me the nxet best model is a 1993 onward amp. Prices are better and they are close to the 1960’s spirit. Personally , if I want a valve amp then that is what I want . not the half way house of a mix of semiconductors and valves. I wonder if the semiconductors in these new generation of hybrids will be available to repair them in 50 years time.

a 1963 Top boost Vox AC30 still can be renovated and repaired plus all the valves are still in full production. I doubt if this will be true in the fast moving world of semiconductor chips.

Original 1963 fawn Vox AC-30 amplifier head. Early Vox AC-30 heads are rare enough, but to find one 100% original in fawn is becoming almost impossible. This amp is completely intact and still retains; original fawn tolex and original era appropriate grill cloth (still has original gold piping!), original candy panel control plate, all 3 original matching Woden transformers, 99% of the original capacitors/transistors, all original pots and wiring, original hardware, original chicken head knobs, and original JMI tremelo/vibrato footswitch!

The chassis serial number is XXXXX, which indicates a 1963 production date. The cabinet serial number (which is always different from it's corresponding original chassis) is 604, which renders this the EARLIEST AC-30 cabinet of it's type according to the "experts." Various capacitors have a 1963 date code as well. This amp sounds absolutely incredible.

The "Brilliant" channel has the sweetest and most musical natural gain of any AC-30. It is loud with plenty of headroom, yet sounds MUCH better than your typical AC-30. Of the 50 Vox amps we have had in our personal possession, this is probably the best. It has the creamy overdrive of a Marshall 18-watt Bluesbreaker, while producing substantially more serious highs complemented by mic-blowing lows. The "Vib-Trem" channel sounds just as good but features the best amp Leslie-like Vibrato ever available built in to an amp.

The normal channel produces slightly less output, but due to it's originality and sonic quality of the other channels, we have been reluctant to perform an unnecessary service. Electronically, the amp is 99% original. All of the important components are original to this amp. The only changed electronic parts are; the speaker output jack (changed from the 5-pin to a more practical quarter inch), the power cable, and ONLY two capacitors.

Otherwise the inside of the amp looks just as it did the day it was made. Cosmetically, the amp is completely original except for the small Vox logo. Otherwise, the amp is physically 100% original including; tolex, grill cloth, handle (with early Marshall-style brackets), candy panel, knobs, chrome feet, back panel, Vox serial number plate, and screws.

The condition of the fawn tolex is very nice. It has aged attractively and appears to be evenly discolored by smoke. The grill cloth is also in pretty good condition, but does exhibit the typical fraying and wear that Vox's commonly display. There are several large scratches on the back that have not compromised the integrity of the tolex, and although the scratches appear to have not damaged the Vox serial number plate, the scratches do NOT continue under the panel.
