Two power supplies blow fuse

[h_andree]

Do you guys think the rectifier is damaged?

How would I test this without dissassembling the amp?

Thanks

I think I found the problem. I was testing the rectifiers
and the measurements did not make sense.
Then I dissassmbled it and I looked at some other
bridges I had in a bag. It turned out the polarity
on my bridge is mislabeled!!!

This took me almost a whole day to figure out.

I will let you guys know if this has solved the issue.

Twice look than once cut .

I checked the polarity many times (Visually).
I actually never measured the bridge. Both
bridges that I put in are labeled wrong. The
company must have printed their information
on the wrong side or something like that.

How many of you measure the polarity of
a bridge before you assemble the amps?
I know I will next time.

That was it. The fuse does not blow anymore.
Also 2 power supplies including rectifiers can
be hooked up to one transformer. I still did not
try it with sound though. One step forward.
