The little red ones are between the big Nichons and BR1 and BR?
Probably a bypass cap on the outputs of BR1 and BR2.
I'm quite surprised that it smoked!
I would store the dual amp you smoked in the garbage.
BR1 and BR2 are next to the little tin box?
They would be bridge rectifiers for the Power Supply.
Thanks for the info!
Is there any way to test the bridge rectifiers with a test meter or are they not likely to have fried?
