Power Amp Help/Advice Needed

[goraman]

It is not funny when this kind of thing happens, the only time something like this has happened to me was a toroidal transformer in a new DAC.
You will want to check all psu capacitors and the rectifiers, I would fit slightly stronger transformers in there if it where an option. I am told the higher VA the better.
Some of the best audio grade are used in older copy machines and medical equipment Switzerland and other Scandinavian country's.
If they are made in china forget it.
