I have the above radio (board # EPT069610Z). Radio was at no TX at all but did get the carrier back but I'm only getting about 50% modulation at 4 watt dead key and it's swinging to about 8 watts. VR 18 (low power) has no effect on dead key and if I adjust VR 14 (high power) to over 6 watts I loose all modulation. VR 16 (AM Modulation) is wide open. Radio is stock with no mods and using a stock mic. Any help would be appreciated. If there is more info needed please let me know.
Thanks John
P.S. I did readjust the bias current to specs in the service manual.
