I did not change L33/L34 to make the new L33 which is one coil for the two spots cause I couldn't find one.I also did not know what to do about D90 , in the picture its a resistor. I cannot adjust the bias at all, its stuck at 5.05 volts with any variation of the VR's. TR51 gets real warm after some audio. I get a 6 watt dead key with a 20 watt pep swing. The front RF Power knob has little to no affect. It also seems as if I can only raise the modulation a little bit, below half way on the mic gain has no effect, it only reacts above halfway. The VR14 is opened all the way.
