So a resumè:
Yes you can convert a HIFI amp to a guitar amp.
- My idea is to build a separate preamp with everything inside to:
- Increase the input sensitivity if necessary. Give the guitar input a high impedance.
(Take measures against RF disturbance. This is an issue with sensitive, high impedant inputs.)
- Make the output of the preamp deliver a signal that is suitable to drive the AUX, CD, Radio or whatever input of the HIFI amp you wish.
- If you want to overdrive the amp, do it in the preamp and not in the HIFI amp. This way the HIFI amp will live longer and you can manipulate the character of the overdrive to sound the way you want. Also you can use the overdriven signal at lower volume levels.
- Build the finished preamp and the entire HIFI amp in one cabinet for easy connection, transport and for protection against the rough life on stage. Realise that HIFI amps are mechanically not designed to be dragged about. It also makes it easier to swap the HIFI amp if you decide to use another one.
