A couple of weeks ago several of you were very helpful with a problem I have with my Radford amp. Thank you all. I am back again with a specific question / request. I have collected several circuit diagrams, none of which are right for my amp, but I now know that Lee has a similar build. [B]Is there anyone who knows of, or has a diagram for the circuit of a build for the Renaissance which used ECC81 and ECF82 valves, plus EL34's in the output?[/B] Mine is labelled STA25, Lee's is STA35 but actual build appears very similar. Thanks, Jon
