The only difference between the AC30CC2 and AC30CC2X is the speakers. If 'Beatle tone' is what you are after, it lives in a top boosted AC-30 with Vox Blue Alnicos, like the AC30CC2X. These are the same speakers that George and John used in their AC-30 amps in 1964.

I like the Caldwell mods but feel I'd like to split the difference between those cap values and stock. The AC30CC2X utilized two 12' Vox Alnico Blue speakers, by Celestion. I'm also considering bumping that Top Boost cap from 68pf to 82pf while I'm in there as you suggested. I'm guessing there's a lot more contrast between the Brilliant switch being on and off now? How much darker does your normal channel sound with the 30pf instead of the 68pf? Just to make sure I understood what you wrote, you replaced the 68pf cap on the Normal Volume pot with a 30pf? And then changed the brilliant switch cap from 68pf to 150pf? I was also thinking about using a higher value cap to get some of that Brilliant switch high end back.

I'm fairly pleased with the Top Boost mod with the 68pf cap, but as you mentioned, the Normal Channel sounds better than stock, but the Brilliant switch essentially does nothing at this point. I had my Vox AC30CC2X modded by Don Butler a few years ago, and then had a local amp tech do the additional Lyle Caldwell mods a few months ago. I was very interested to find your blog entry on this. For the modifications I am doing, I am just going to have to solder them to the visible side of the panel, seen in the picture below and be careful. I guess I'll have to desolder the switches in the future and find another way to remove them from the panel. That usually means that the switch body itself is broken internally. I actually scratched one of them up trying to turn it and noticed that the threaded part of the toggle switch was turning with it. The only issue I came across is that three of the chrome decorative threaded caps for the four toggle switches on the control panel PCB would not come off. There are four main PCBs - The power section PCB, preamp PCB, control panel PCB, and the rear panel PCB - which houses the effects loop, speaker jacks and reverb I/O.

It's a very ingenious design, while it takes a bit of time to visualize where everything is, the layout of each PCB is very easy to view, and you can follow the circuit design quite simply.

The rectifier, power tubes and transformers are mounted up from the power board - but the preamp board is mounted vertically, with the preamp tubes extending horizontally. Instead of all the tubes mounted up or down, the AC30 uses many different planes. Unlike other amps I've worked on, the AC30CC chassis is a little different. custom reproduktory: AC30CC1 1 x VOX NeoDog, AC30CC2 2 x GHS12-30 (Wharfedale), AC30CC2X 2 x Celestion Blue' ALNico 15 W. After removing the back wood panel, disconnecting the the reverb and speaker cable, there are four screws holding the chassis in place, then the chassis slides out.
