Thanks Craig.

Now I need to source one.  The reverse log taper ones are scarce...  Ugh.

The RF gain pot is a reverse log taper. 

Regards,
Craig

Morning Folks,

I need to replace my RF Gain pot.  I'm thinking it needs to be a logarithmic
taper pot since the linear one I replaced it with gives me all of the action
between 8 and 10 on the knob.  Can anyone confirm or deny it's a log taper
pot?

Thanks!
John
