I did check the tubes. All were Good. However when checking them against schematic I noticed that I have a 6K6G in the place of a 6F6G. I believe it is a direct replacement but how it affects the voltage No clue..

I lowered the input voltage to 117 volts. The B+ now reads + 330 volts using a VTVM.. The bias reads -.68 volts.. Radio still works great.. So I guess its good for now.. I guess I will put it back in cabinet and back to living room..

Thanks all
