Default Re: Murphy U472 NO FM !

I had this fault on my Murphy U502, does it only screech when you are on a station?
I traced my fault to duff caps on the screens of the 10F18's. I notice your set employs one of these. Go for that cap on the screen of the 10C14 first and see what happens. It's cap C23 0.003uf. Also the other suspect if that didn't work would be cap C39 0.005uf on the screen of the 10F18.

Good luck, cheers.
