[Boatanchors] R-390A FIX FOR THE 3TF7 PROBLEM

[William Kipping]

Hi to All 
 I recently purchased an R390A, (my first)  No surprise the 3TF7 ballast
tube is open. I know of the three easy fixes,(45ohm 10w resistor, or a
jumper and use 12ba6s in the pto/bfo, or use a 12BY7 as a load)   Thought 
I would ask for recommendations on which to use. Also if using a 12BY7 as
the filament load fix , are any other jumpers needed on the tube socket or
just a plug in Thanks for your advice Bill KE7KK
