[QUOTE="Hennie, post: 27612, member: 20"] If you could re-use the transformer - maybe. The A500 lacks a centre tapped secondary transformer winding as far as I can see. Each channel has a separate transformer winding and rectification / smoothing though. So it would be possible to construct one balanced PSU for both channels using either a two diode recifier scheme or a bridge rectifier. With a bridge rectifier you would obviously double the total supply voltage swing. Also, the amp couples to the load via electrolytic caps - kinda old fashioned but popular with pro amps. I don't know how big the caps are but the output impedance would be reactive at LF. Maybe something to check out if you want to use it as a sub amp. [/QUOTE]
