    Hello there. First time posting on this site, but have been visiting for some time now.
    I have a Fender Super Champ X2 that stopped working. From what I have read online, the problem is a bad DSP board and it can't be fixed/replaced.
    So I have the following questions:
    1. The amp has a clean all tube channel (ch1) and a digital effects and amp moddeling channel (ch2). Could it be possible to bypass the digital components and keep the clean channel with simple tone and volume control?
    2. Can it be modded into something else? Say maybe a Princeton?
    3. I also own a 90s Peavey Minx 110, a Frontman 25r, and an old Fisher 600-t receiver from the 60s. Could I use parts from all these amps to build at least one good tube amp?
    Any ideas or suggestions welcome. Thank you.

    Well, for starters, IIRC the clean channel is still processed through the DSP board, so it may not be as simple as just bypassing the board; however, there are other minds here at TDPRI who can probably provide more detailed info :).

    Welcome to the fun house!

    Someone needs to troubleshoot the amp. Online research can't determine what's rong with it. If it's under warranty (older ones are 5 years, newest ones are 2 years) Fender will replace it instead of servicing it. If it's not under warranty, a tech who's good with SS amps can likely fix it: other than the PROM that holds the voices and other data, it's mostly commodity components that are readily available. Sometimes the best option is to buy another used SCX2, although they are seldom dirt cheap. The head will be cheapest and you can just swap its 'brains' into your combo, if that's what you have.

    @cbh5150 is correct. Channel 1 is a voice, just like the other 16 voices on Channel 2. There's no tube preamp. There's only one SS preamp and DSP stage.

    The SCX2 is 99% Princeton circuit after the SS preamp, but for all practical purposes it can't be converted to all-tube. There isn't room and there isn't chassis space available to do that. Far, far more trouble that it's worth to attempt. I suppose you could craft something out of your other amps, but that's not a path to success unless you're an experienced amp builder.

    If you want to build, kits are available for the 5F1 (Fender Champ) circuit. That's a good place to start. Search the amplifier discussion forums, here. TDPRI is a deep resource for amp tech and kit building.
