Hi Ashley,
Thanks for the quick reply on my problem!
My low voltage supply is good and my unadjusted bias is -80. I haven¡¯t diddled with that much because I just built a bucking transformer that lowers the line voltage to 111vac but haven¡¯t wired it in yet. I felt the -80 was a bit high but wanted to concentrate on the bigger screen voltage issue. My HV supply is good at near 700vdc and that will come down a bit with the bucking transformer but not 175.
The only thing I haven¡¯t throughly checked is the clamping circuit because I didn¡¯t feel that it wasn¡¯t the main component to drop the screen supply. The manual¡¯s adjustment proceedure for the clamping circuit requires operation of the amp circuit to 230ma. I feel a bit uncomfortable doing that with over 400vdc on the 6146 screens. I would like to get that down before messing up a pair of finals playing with the clamper circuit.
I¡¯ll definitely take a closer look at the clamper components at your recommendation. I did check the clamper tube (and all the rest of them before firing it up on a variac.
Thanks again,
Tom N5AMA
