You got it.
The amp has been running for about 4 hours, I left and came back 1 1/2 hours later to the smell of burnt electronics.
The big cap (C1) blew. The fuse blew, probably saving a lot of parts.
Tested the transformer, its fine. Tested the PS board after removing C1, its also fine -- giving me a B+ of 255 V.
Next would be to see if the amp boards are damaged.
I got the kit from Glass Jar, so its probably just a bad electrolytic. Now, I'm also suspecting the other 2 big caps. I wonder why it blew????
Sure you got the polarity on the caps right? Its odd that your B+ is 255V and these blew up, could it be heat?
