Hi all, is it possible to put tactile markings around the plate and grid 
knobs on a valve radio for point of reference in the event one is unable 
to aquire a tone osilator for tuning purposes?
I don't want to limit myself to just one solution as I might not be able 
to aquire a tone osilator or find someone to install one should I find one..
if it's a bad idea, please let me know. I'm just exhausting all 
possibilities.
I did once use to use a heavily attenuated receiver for tuning, and it 
seemed to work.
