WAD Stereo 300B PP Circuit.

Slightly simplified version of the circuit for this 1994 WAD classic.

The schematic of the stereo WAD 300B PP amplifier.

This circuit differs from the original:
The switchable feedback option has been removed, as is common with most builds.
Likewise, R12/R13 reflect the higher values commonly used (originally 1k2).

It is common for the 6.3v AC heating for the miniatures to be DC rectified, for C1, R3 and R4 to be replaced with 'battery bias', and for PSU capacitors to be bypassed.
The circuit does not show these options.

Nice.
