Thats what I needed John; thanks now I can order. What are you building or listening too John if I may ask? Now with the completion of the Eico and the tube rec EL 84 I need to start thinking about an amp. 1 I believe that you use less expensive passive parts; matched carbon comp resistors and decent caps; Orange drop 716's etc. 2 A reasonable homebuilt chassis and instead spend the money on tubes and transformers. What do you think? Good connectors also. The one thing I need to study is good grounding and safety practice. I know lot of the safety wiring issues compromise sound but I want it safe. Bus ground or star ground?
