Several weeks ago the power tube at V2 on my R8 red plated. Today I removed the bottom cover to begin the upgrades and mods and to see if I would find the cause of the red plating. At first I didn't find anything. But later looking with a flashlight and at the right angle I found 3 resistors in the power supply section damaged. And I had thought they were of better quality than the ones in the R8 Stephi had worked. Wrong!
