Almost always +/-15VDC. What are the rated voltages on the caps?
Most of that Chinese stuff uses 16V caps on the rails.

I have a Behringer UB2442FX Eurorack mixer. Before the flames start,
I liked it, when it was working. It did exactly what I needed.

It died, out of warranty, and the switching power supply looks to be
toasty. Behringer US doesn't have PS modules yet, so it looks like
board level repair is where it's at.

It uses very close to a demo circuit from Power Integrations from
their TOP245Y chip. However, I don't know what the final voltages are
other than there should be a +5V (Based on the 7805 regulator) and
there should be a 48V. There are 5 voltages available, guessing from
the connector.

ANyone help out with at least the voltages coming out of this
doohickey would be appreciated. Any other help would also be
appreciated.

Thanks
