Well I've read a great deal on these forums about this amp and I have learn alot about it and made mine perform better and better.
I tuned the low and hi SWR inputs to the amp after learning what those adjustments under the driver tubes and the hi-low switch were for. Thanks for that info.
Still a question i have now is...Under the driver tubes there is another adjustment, a recessed tuning adjustment, not the one for the swrs. Just curious as to what this is.
Anybody know ?

If you mean the metal-body (usually) trimpot between the rear driver tube and the rear panel, facing down from the solder side of the driver pc board, that's the meter's sensitivity adjustment.
