RE: Motorboating on 1935 radio I rebuilt

John -

Go thru the resistors and look for ones that have drifted up - often a grid leak in the audio section. You can also trouble shoot by paralleling a resistor of approximately the correct value across an existing grid leak resistor with clip leads.

If you need a schematic post the brand/model and tube lineup - I may be able to locate it.
