Even "invented" PWM based sine-wave generation once before sleep ;-) The problem always was that in the end one needs a transformer, which is what I always wanted to avoid in the first place..

You can't. There is no way around a transformer in this case.

The only other way is a serious redesign of the C64 power supply (the 
part on the C64 board).
