This amp appears to have a basic unregulated power supply which is protected by a 1A fuse on the input side (F101), and a 3A fuse on the output side (F102).
Power from mains through F101, into the transformer primary
Unknown voltage out of transformer secondary through F102, and into a full wave bridge rectifier, and then through a 63V 4700uF cap. I'm assuming the secondary voltage is lower than 63V, lol
F101 is blown, and If you guys have taught me anything it's not just to replace a fuse and plug it in..
On visual inspection of the board, the area around D109/D110/R179 has gotten hot and discolored the board, and I'm currently trying to trace how those might contribute to my problem.
Do you guys have any ideas where I should troubleshoot?
