I have a Counterpoint 5.1 tube pre-amp, after I found the 2A fuse is broken then I put a 3A fuse to replace.
When I powered on, I saw smoke came from the power supply and smell the smoke is coming from the transformer.
Is there any suggestion, I need your help !
Thousands thanks in advance.

Suggestion 1: Don't overrate fuses. They are there for a reason.
Suggestion 2: Find, and fix, the problem in the amp that blew the fuse in the first place before trying to power it up again.
Suggestion 3: Remove the power transformer and check it for shorts, etc. If it seems okay, power it up on its own (with a proper fuse) to see if it works. If it does and you have fixed the problem in the amp, reassemble it and test (with the proper fuse.)
Re: Re: smoke came from transformer
Smoke coming out of the transformer is a VERY good sign that it has a short.

Suggestion 4: Keep the lid on and don't let the smoke out. Everyone knows old amps are powered by smoke!! If that fails , replace the transformer and check the rectifier and caps.
