Thanks brian. But that's getting a little over my head. I'm not exactly sure
where to take the measurements from or what to look for.
Maybe this is something someone can walk me through at the next TPUG meeting?

Check resistance on both primary and secondary windings of transformer to
verify that it actually defective.
If defective, a replacement transformer with similar specs, should not be
difficult to locate.

Thanks scott, I actually just found the same manual, but it was posted on one
of those heavy ad based manual sites. They make it nearly impossible to
navigate a service manual. This one is way better.
It didn't take long for me to check the voltage coming out of the transformer.
Looks like there's nothing there...
I think I'll check the warranty card and maybe drop by the pharmacy location
and see if I can get a new transformer.
In all seriousness, I feel like it's going to be easier to find another 802
then it will be to find a power supply for one....
Thanks!

Hey Ben, check this out:

I searched for “commodore MPS-802 circuit diagram”. 😊

Yes, fuse is good. First thing I checked when it was totally dead.
And yes, on closer inspection, that that might be glue.
I'm not an expert, but I can trace some power wires and connectors and check
for continuity here and there.
Does anyone know what the voltage should be out of the transformer?
Ben

Hey guys,
I pulled a Commodore MPS 802 printer out of storage. I figured it would be a
nice upgrade from my MPS 801. Unfortunately, it did not power on. On closer
inspection it appears that these two capacitors (attached photos) are done.
Actually, I don't think those are bad. Most large caps have some glue on them
to physically hold them to the PCB. From the pics, it appears that is jsut glue
I believe the 802 has a fuse. Is it known good?
