[AMPS] No Blocking Cap :)

[alex]

A while ago I had to design an amp which had to have an extremely low second
harmonic. The obvious choice was the deployment of a push-pull final stage.
As such we have used two 8877 in push-pull, transformer coupled to the
output tank. NO blocking cap :)

We were able to get 4KW continuous duty (cooled by a big air compressor)
with
a second harmonic down to -160dB :)

If you have problems with your blocking cap, consider transformer coupled
push-pull stages.
