Panasonic microwave model NN-S446BA open power transformer
 

There was a brownout. The transformer is part number ETP41KCN41UU.
There are two secondaries. Nearby are two electrolytics. One is a 16V
and the other is a 35 volt. So I'm thinking perhaps DC voltages of
maybe 12V and 24 V? Would this suggest that the secondaries might have
been 10V and 18v secondaries? This may sound like a useless idea but
would anyone possibly have the specs for this transformer? If I could
sub the secondary voltages I can determine if the control unit is
still good. My other idea is I had read someplace some time ago that
there was a way to determine secondary voltages with an open primary.
I can't imagine how this could possibly work but if anyone has any
ideas as to the transformer specs or how otherwise I might save this
thing I would be very grateful. Thanks, Lenny

The rectified secondary outputs are +18V and +10V.

This is more than I ever could have hoped to get! Now the dumpster
diving can begin. Thanks so much for the service manual. Where did you
ever get it? Lenny

It's hardly a service manual, but I used the following Google search:

It might not be a service manual, but it has all the information
anyone could need to do repairs. I hope aI can remember what you did
when I need similar information in the future.

If you can't remember, then select Advanced search and choose your
