Hi,
Just thought I'd document my api-312 500 series build.
Single sided pcb which you can make through the iron on method using laser printer, winding my own txfs, 48v, -10db pad, polarity switch, di input, gnd lift, output attenuator pot.
Gonna use a couple of 2520 op amps I had left over.
Have design and printed pcbs and going to put them in ferric chloride then drill.
Will detail parts etc once I get to that stage.
