Hi,
Does anyone know much about PT Too power supplies? Does anyone know how they work?
When searching the internet and asking on other forums, no-one seems able to help as if these are a complete mystery yet from looking at the circuit, it seems to be a very simple amplifier driven by a (complex looking) sinusoidal waveform generator..
I am wanting to revive my dead one which failed when I accidentally turned it on without the motor connected. Surely this would just mean rebuilding the TDA2004 amplifier circuit as I can't imagine any damage would go back further than this. Could this be correct? The opinion I get from people is that when a PT Too PSU is dead, it is dead forever but I just don't believe it..
Incidentally, one of the three PSUs I've amassed has all the chip identities intact so I can show all the CMOS chips that are in the circuit should anyone be interested - perhaps someone wants to clone it? Just let me know and I'll get snapping with my camera.
I'd be greatful for any help.
