Hello, I made a quad Amek 2500 mic preamps rack, so here is the layout if some of you want to etch some single side PCBs :

I forgot that the preamp needs +/-16V, but I have spare PeterC PSU that supplies +/-15V, can I use it? or maybe do some modification on it?
What current does the amps need? I have 5A trafo, is it enough for 4 channels?
mjrippe said:Your +/-15v will do just fine. I don't know the current draw of this circuit but I would bet the PSU can do +/-1A with good heatsinks. Should be fine for four channels.
saint gillis said:Yes I found 21mA per rail, so yes you might even not need big heatsinks..
Thanks for the 1Ms, I'll add them to the bom.
Nice looking job!
