The tremolo circuit changes the bias, which alters the mains current draw, which must have been triggering the loose mains fuse into rapid oscillation of input voltages due to the transformer inductance etc. So, it was the mains fuse holder within the IEC socket that had been randomly intermittent the whole time. I own more expensive amps (hand-wired Matchless Lightning clone. Spring reverb with dwell switch, footswitchability, and tone. The AC30 CC series is a killer value, and dont let anybody tell you otherwise. 2 blendable channels feature fully variable tremolo with footswitchability, a custom EQ switch on the Top Boost channel, and Brilliant switch on the Normal channel. When I pushed it back into place it fell off. The Vox AC30CC2 30W 2x12 Custom Classic Combo is a solidly built tube amp that delivers outstanding sound quality. On inspection, I noticed one of the fuse holder fuse retaining clips was splayed. It was then I noticed that pushing the IEC socket fuse drawer back into place felt far too weak. Ive seen more modern amps with 470r ones, and I like to use 1k with a few other tweaks. So I thought to try and save the mains transformer from possible catastrophic damage I would fit a fast blow 1A instead of 2AT and gingerly test further. Features: 10 Reviewers score: 9.3 Superb Users score: 8. Vox also used 100r screen grid resistors in amps from the beginning, and really only got away with it because of how rugged Mullard tubes were. I could only think that somehow something is breaking down randomly, maybe HT is going down the heaters or something, only I'd previously established it wasn't a valve problem. Switched dim bulb off and horrible noise, both HT fuse AND mains fuse blown this time. The difference between the two wasnt large, but the CC2 held together a bit better at higher gain and volume settings, and the channel link switch I found quite useful. Turned it on with Dim bulb in circuit, fine. Tube Combo Guitar Amp from Vox belonging to the Custom Classic series. Update, this has been one of the most difficult and frustrating valve amp repairs I have done.Īnyway, I had it soak testing for hours no problem, so I put it back in the cabinet, thinking replacing the tremolo cap must have fixed it.
