I must be getting better. First amp cobbled together in 10 years. Works on first power up.
Used the three chassis that housed the power transformers and circuit boards on a 2006 vintage DIY ASR Emitter II. Used a battery section for the LM318 in that one. The low voltage supply is much improved in these latest boards.
Thanks to Dario, George, and all the others who contributed to making the supply of My_Ref boards both available and much improved.
Used many of Dario’s recommended upgrade components in the build. Also to match better with the pro interfaces used as sources converted to balanced input. Used Cinemag 15/15B input transformer to do the conversion to single ended. Terminated with 20K instead of 100K.
Fitted a few of my thoughts on how to optimize these amplifiers. But a few pictures
