Default Re: Help needed restoring a Murphy V310

Hi Nick, The awful picture I posted earlier (post #126) was to show off those horizontal lines, which you kindly told me were flyback lines. Please see the picture below as this is what the set can produce at the moment. I didn't think it looked too bad, but I will bow to the opinions of experts .

I had set aside today to work on the LOPT, so although I'm still uncertain about the rattling EHT stick, I've opened it up! The oil seems very gritty with large build ups around the connections to the rectifier heater. there's also something else in there, is it a resistor?, that's covered in crusty coating. Although I can't see any carbon I guess this stuff still might be conducting something?

I was advised to remove the heater winding but it's right next to the overwind and I'm worried about damaging that. Not sure what to do now?


Regards
David
