Default us amp md3d

I got amp friend that didn't take care of it. When I received it 2 caps on the output side were popped and the 2 of the legs on choke had broke. All 24 power FETs are shorter including 3 output FETs.

Power fets are marked irf1010n, will irf1010npbf work? I didn't see a difference other than lead free.

Where the choke leads broke I can't get them soldered back in place . Can I unwind 1 turn and solder it back in?

I called RE audio and asked for the service manual. They lady said they would email it but its been over a week.

The PBF will work.

It would be better to extend the wire instead of taking 1 turn off. In some instances, taking 1 turn won't make a difference. In other amps, it could cause both the inductor and the output filter capacitors to run hotter than normal. I'm assuming that you're referring to the output filter inductors.

Yes, you are correct again.

Can it be extended with ANY, same size, solid core copper wire since its only a small piece ? Something from the hardware store?

Any wire the same size or larger will be OK.

I finished up the repairs and everything looks good.


Thank you Perry.
