40-201 now has power
#20

Yes I still have some more that will be replaced, just have not all the necessary parts on hand right now. So far two of the old type capacitors have turned out to be shorted. They will be replaced once I get all the parts on hand. There are a few in the RF circuit not replaced yet and there are a few resistors that have not been replaced either. I think I have most of those on hand and will concentrate on getting those taken care of too. So many resistors in the set have turned out to be significantly over value already. I am using 5% tolerance resistors to replace them. The film capacitors are either Mylar metalized film types or Polypropylene metalized film types. The only exception were the capacitors in the AC input circuit which I replaced using some ceramic disc Y2 types made for such service. They are far safer than the OEM types that were contained in the bakelite enclosed OEM units. If one of the caps yet to be replaced stops the noise, I will indeed be happy.
