Hi Again,
Ok, have moved on to the 3rd amp. 1 and 2 repaired using this board. K100-5 and K200B-1 working great!
This is the 2nd K200B-1. Initially, I had the same problem as the first 200, meaning the bright side did not work. So I performed all the tasks that I did on the first one to resurrect it. It worked. Life.
But, when cleaning the bright switch on the bright side of the amp, I noticed that the 'stops' in the switch weren't doing their job! I can switch the switch knob a full 360 degrees as many times as I want. And no, the knob isn't loose--haha. There are maybe 8 dips in the switch, and the connection obviously works on only 2. The other side is fine, and by comparison the defective switch is OEM. I could leave it as is, but I know that it isn't right. I also tapped around with the plastic end of a small screwdriver on the circuit board of the Bright side, and got a mild cracking on all 4 pots. I will try this tomorrow when I am sure the cleaner is all dry, and see if it repeats.
Additionally, with still having the non-grounded cord on the amp, the electronic hum is very loud on the Normal side. On the other two heads I repaired, that diminished greatly when the cord was replaced. Maybe this one will as well.
