Why solid state? Tubes and direct drive ESL is a perfect match.
My Beveridge is playing just awsome and you can see the schematics above nr:73
The tubes are dirt cheep and there is a lot of them... so what are you waiting for guys and girls?
The schematics shown at post #73 contains some erratics :
Both bases of differential amp Q6 and Q7 are tied together, in this way they will output nothing.
Q4 and Q5 are fully shorted at all pins.
