This makes sense in my head, but I thought I'd run it past people smarter than I.
I've got the color-out issue on one of our two 9200s. I already made a thread about this monitor here but I got a different question now. mecha187 suggested replacing the resistors with a higher resistance and replacing the color transistors with a beefier NTE2501 (higher max voltage). However, as he admitted, it won't look as good, and since this is an in-the-field machine that's expected to make money, that's not desirable. I want to take a slightly different approach -- use the current 1.35kOhm resistors, replace the color driving transistors with NTE2501s as they die, at the same time fitting them with significantly larger heatsinks (I'm thinking 3W@25C). Will that work out? Could the larger hunks of aluminum screw with the magnetic fields in the tube?
-E- You know, I now have a 9400 neckboard that doesn't have a tube to go with it. It has "H." (Hitachi?) 2SC2682s on it. Slightly lower voltage tolerance, but it just might work.
