Philco Model 20 Grand Cathedral

The problem can be remedied by using much smaller cap in the plate detector cathode but that will come at the expense of the gain and thus the sensitivity.
Hi Morzh:

On the attached schematic, are you referring to cap #19?  If so, what size cap would you suggest I try to see if I can reduce some of the distortion?

Thanks again,
Jay
