Default Punch 150 that is stripped, is it savable?

I have a old school 1st generation Punch 150 the one with bipolar 2N6488 & 2N6491 outputs. Anyway i was given this awhile back it was already broken, missing parts i just wan't to know if it's repairable, savable? I don't wan't to throw it out or nothing i'd like to see it working again.

I tried taking pics of it so i was using my HP laptop pics aren't top notch but it should give you an idea whats up with this amp.

It's likely salvageable if it doesn't have a shorted transformer. It WILL be time consuming, however.

I borrowed one of these to answer a question in another post so let me know if you need component values.

I don't think it does i applied power to it and it did nothing. I wan't to know what MOSFETs can i use in place of the original BUZ11's? and RFP18N10? (one of them has a broken leg). And it's missing emitter resistors, driver transistor, and a small transistor located in between the FUSES. Ohh and a filter capacitor.

I'll let you know if i need some values on anything. Thanks

I'd use 3205s in the place of the BUZ11s. You'll need to replace the 390 ohm gate resistors with 47 ohm resistors.

I'd also recommend replacing the two MPSA56 driver transistors. They have quite a few random failures in these older amps.

This amp has IRF3415s in place of the 18N10s.
