Re: Cooper Smith Amplifier
Hi Gonzini,
sounds like Ed has more info to go on than I do. I'd second the seriesing up of the output windings he suggests- otherwise the NFB has no complete circuit.
It'll be interesting to see whether the circuit is just the phase splitter and output stage a la Mullard, or whether it's a concertina phase splitter using one of the ECL82 triodes, with the other as a preamp.
In any case, given the size of those O/P TXs, it should sound quite good. They're about twice as big as the ones in the Pye Black Box amp- more like the size of a 5-10 output tranny!
