I finally got this baby working :-)
I changed the LM324 with a TL074, changed the other LM with a TL072 and
put a 100k instead of a 22k. I used a SGS Thompson 4516.
Apparently that other 4516 wasn't working. I think it was a Harris one,
if their logo is an "H" ;-)
Been playing with this switch a couple of days now, it's real fun.
I found a second sequential switch PCB in the batch of PCB's I
inherited, going to built it right away.
Cheers,
