OK, I'll start off with the story from the beginning. So I have received a Kris Big Boomer box and have been messing with it for quite some time now. When I first got it, it had a hum in xmit, but was getting full power. So after having a friend of mine replaced the filter caps and fixed some other odds and ends, after putting it back together I was only getting half the wattage. So I took it back to him to check the tubes. I was there while he was looking it over and he was explaining to me that he thought that the factory had made it so all the tubes were 6LQ6;s. Well, to make this long story short, he had put the driver tube, 6JG6A into a 6LQ6 slot and a 6LQ6 into the driver slot. The 6LQ6 was getting its voltage in the driver slot due to the driver slot also having a top cap; but the driver tube was not getting plate voltage in its slot as the 6LQ6's plate voltage comes from the top cap; but the 6JG6A tubes plate voltage is thru pin 9 Well, I finally figured out that issue and now the tubes are in their correct slots.
For a little while I have been running a RCI2950 into the amp and I was getting around 275w peak out of it on AM. The 2950 has been detuned to be able to run a low drive amp. Well, today I was playing around with a Cobra 29 LTD chrome and installed variable watts on the RF gain and slapped a capacitor and resistor in there to make her swing. Hooked this radio up to the amp and now I'm seeing a little over 325w peak on AM. But I noticed on the AVG scale I'm getting backwards swing. Also noticed the SWR light on the radio coming on when I modulate. Which probably means I'm getting some reflect and the radio and amp are probably not in tune with each other. With the watt meter after the amp right now I'm not getting any reflect back from the antenna.
My question is this. If I put the watt meter between the amp and radio and it shows a high reflect under modulation. Can I adjust the input tune in the amp to reduce my reflect? What effect, if any, will this have in output watts when adjusting the input tune? I already know the amp has an input tune and know which one it is.
