Hi;
Anything is possible but in most cases I have seen a small change in the
settings will make a big change in performance and tube life. I would
suggest you hold out for a tone system. Speaking of which, if you can find
something it is much easier to use a meter and tone system in the antenna
line rather than trying to connect a tone to the radio's meter. I connected
a tone oscillator to my drake tr4 back in the 1970s and it worked reasonably
well. Then I got the brilliant idea that I should have a plug so I could
plug and unplug the tone unit. It sounded and worked reasonably well until
I discovered that touching the socket when nothing was plugged in could give
one a bit of a jolt. Nothing life threatening certainly but there was
definitely some voltage across that meter.

Subject: valve radios revisited
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.
