I decided to cram on 4 PGA2500 logic controlled pre amps onto one board.

I'll make two of these and stack them on top of each other with the circuit protection board on top I think. I ran out of 4.7uf caps today again, so waiting for the post man now..

I've started drawing up the 8 channel Pre amp board in Circuit Maker so that should be public once I've finished. I might just print the 8 channel PCB if this this 4 channel works ok.

heres a pic of the bakelite prototype, yes I said bakelite !!! :) thought it smelled like bakelite, looked up online where i bought them, yes they are !!! anyway , who cares what there made of , if they work ?
