Alchemist Forseti APD21A Pre Amplifier PSU
Hi
does anyone know the output voltages of the transformer in the Alchemist Forseti APD21A Pre Amplifier's Power supply unit? Its a small torroid with two secondary outputs each with a 0v centre tap so its six wires in all. The output on the DC plug end is two +v and two -v with one 0v. The manufacturer no longer has data on this transformer and its dead short so no volts out! I think its about 25v 0v 25 each winding but need to be sure. The colour codes on the PSU are 2 reds 1 black winding one 2 whites 1 green winding two I await your replies thanks Phil |
