Hey guys, I just put together the SSG and it's not working so i tried to switch out the lm3900's after giving the board some continuity testing and looking over the board briefly, i still need to do a lot more troubleshooting but what i wanted to ask about was this,
when i switched the lm3900's out it froze my system up as if there was a short in the power supply.I did some tests to see but couldn't find a short anywhere so i put the old ones back in and system powered back on fine so i switched them out with brand new ones i had and it cooked them within seconds of powering up.
Like i said i still have a bunch of leg work to do to figure out why it's not working but am confused that some of the lm3900's would create what appears to be a short and the others seem to have no effect ?
Thanks, Tony
