Kenwood TL-922A Grid Current I just rebuilt my Kenwood amplifiers power supply. Every things works I have high voltage, Filaments work fine, relays key when transmitter closes the relays. Just no grid current. This is what I did. Replaced all Caps. Replaced all bleeder resistors with 10 watt 50 k ohm from 7 watt 47 k ohm. also replaced all the .01 ceramic disk. The only difference I went with 1000 volt instead of the factory 500 volt value of disk stade the same .01. Replaced every component on the rectifier board. went from 800 piv to 1000 volt piv at 2.5 amps Replaced / changed the 500 volt .01 ceramic disk with 1000 volt .01 and new 1/2 watt equalizing resistors at the same value. Replaced a 33uf 160 volt cap at the filament transformer. Replaced a 100 uf 16 volt cap at the zener diode. Replaced "4" .01 500 volt ceramic disk on the bottom of the 3-500z tubes. The Grids any suggestions. I will open it back up in the morning and re look at all on the ceramic disk.
