Hello to everyone,
This is my first post,
Sorry my english is not so good
I have an antique JVC and Ax-411 amplifier.
I saw one of the channels didn't work. I check the board and I found R769 (10ohm) resistor failed. I've changed with the new resistor but they got harmed.
Now two output transistor and 3.15A main fuse are burned.
You can find the chart, attached.
Does it help?
