Default Re: Help with a HMV TV

Hi
An overheating PL36 with correct control grid drive (assuming you've changed the caps Steve mentions) means excessive damping in the output stage. That might well mean a shorted turn in the LOPT primary, I'm afraid. The width coil could possibly have a shorted turn, and if so might well be getting warm.
Unfortunately a cool LOPT doesn't necessarily mean it's OK, and the only real test is replacement (yes, I know).

P.S. C86 will certainly affect the tuning and hence the width so that's the next logical step.
