Re: PSU's suggestions? (OLD THREAD)

Hi again, 
Time has passed and, my Formant overhaul took a short break because:

a) I bought a few Blacet modules and have been building them and..
b) Discovered girlfriend is pregnant, :-)

BUT... Re: prev thread,(subject line) My Formant PSU is a messy old 
thing and I asked way back if anyone knew if it could be powered by 
the Blacet PSU (which I was buying anyway).

Well, just hooked up an Formant ADSR module to the Blacet PSU...to 
see.. and er.. no... it didnt work.. there was a funny smell and the 
IC's got VERY hot before I ripped out the power... so maybe I blew 
the damn module??

Now The Blacey is +15 0 -15 and the Formant is +15 0 -15, so WHY 
WONT IT WORK?? Should I just tidy up the Formant PSU and use it 
anyway? (It REALLY is a mess) or is there another option?

Hi Mark,
congratulations first. And to the girlfriend too please.
15Volts is 15Volts no matter what PSU you use. Most probable your ADSR was due to blown anyway. Old modules can be tricky. check all PCB tracks before powering up I would say. If something is faulty on the power tracks you might end up giving 30Volts (15+15) to some component that was designed to be working on 15V
