RE: PL504

Hi Ralph, Appreciate the help but the tubes are available and OK. The dealer suspects the issue lies in a mystery circuit that is only specified as an 'output device' on the diagrams. Looking at posts on the GM200 I suspect that this circuit may involve a varistor. I am trying to contact Graaf.
