[R-390] Autotuners

[Kenneth Arthur Crips]

I have the RF/IF module out of my R390A checking to see why the BFO is failing and I was wondering I have the 12BH7A mod' in place for the 3TF7
and have read on this forum about jumpering the socket and installing 12AB7's in place of the 6AB7's in the BFO and PTO positions.  Is this a better setup then what I have now?
