Nice Work, thanks

alexc said:Very nice work there
I'd be really interested in putting a couple of these together just to measure them!

Did anything ever come of this project once the prototypes were ordered? All docs seem to be removed except for the original schematic provided by Whoops. Curious to know if any were built or PCB's made?
Thanks,
Casey

Kevin said:To clarify a bit I use
SSL 82E149 transformerless thats formerly also a E Series but with two LM394, The G series is a bit similiar from that circuit design.
SSL 82E01 Transformer based with JT115K-EPC like the original used on the cards
and the SSL 9k found in the SSL tech docs
I will use switches for gain for all my designs
signalflow said:I've seen the thread but wasn't sure he used the actual G+ schematic. He mentions the transformerless E series preamp(149) which has 2 matched transistor pairs instead of the 1 pair the G+(291) uses.

signalflow said:Having just seen the docs today, thanks to Whoops, I may have mistaken your question. The added Pot on the front panel is an output level control. What I thought you were talking about was the trimmer located right after the diodes at the input.
