Re: Linear Conchord/RSC A11 30 watt amp
Hi Bill, the bias supply can be derived from a resistor in the centre tap, but it is not a good design.
By far the best way is to use a small (say 5va) transformer to derive about 50 volts, even voltage doubling to get a higher output is OK, as the current requirement is so low.
If you want the Geloso circuit PM me with your e-mail and I'll send you a scan.
