[R-390] Big (BIG) Knob wanted

[Barry Hauser]

Hi Jerry

Have you checked with Fair Radio?

Also try Glen Galati of Electronic Dimensions

Another possible source is Leeds in Brooklyn.  Here's the URL:

http://www.leedselect.com/parts.html#knobs

Has one knob that matches your specs (a little bigger) -- a General Radio
Variac knob -- 6" in diameter for a 3/4" shaft.  A bit pricey at $16.

Might have others -- worth a call.
