Wow. Truly bizarre. I am too new to all this to comment usefully on such an
arcane construction...what the hell is that transistor on the inputs for? It
would seem to account for your prediliction to oscillation, if I can follow
what's going on. Anyway, you'd have a constant hum alright; there'd always
be something flowing across one of the inputs, right?
If you want a simple LM386 amp, check out National's app notes for the chip.
Use it like you'd use a standard op-amp, and you would be worlds ahead of
that strange device :)
