1. None of this to me explains "worked a few years and then quit". What, has the vane bent all by itself? Or Did the resistor burn out or cause something to quit?
2. Whenever I replace resistors, even though I pull them from Mouser marked bag, I ALWAYS measure it bedore installing. I never read the code, why bother when you have a meter. Plus colors on all but beige/white are distorted.
3. What is that small yellow cap next to your open electrolytic? Is this what you are putting in? Looks too small for a main filter cap.
4. this blue electrolytic potted with green stuff: cannot claim 100% correct opinion but all light blue coated ones I ever saw are cheap GP caps and have ripple in low tens of mA. If it is a main filter one, not enough usually.
5. After I thougt awhile, I only pot the lead/bottom part and leave the barrel clear, the potting degrades temperature performance and this is what kills them faster. Especially main filter where ripple is high.
