Tube Amplifiers
USAFDave asked:

I 'the VE has obtained a Marshall VS-102R, where the amps reverb recently arrested the operation. My first thought is that the 12AX7 preamp tube can be fired but I wanted some other opinions. Anyone have any ideas?

    The tube in that amp is very early in the signal chain. If that were the problem, then you would have problems with the basic sound of the amp.

    Do you have a problem with both the clean and OD reverb? If so, there’s a problem in the send portion of the circuit. If only one is working, then it’s on the return side.

    Either way, you’re looking at a trip to the repair shop.
