anybody else with a 1076 let me know. the bias cap (I think) in mine does not match up with my schematic. I just dont trust it since it does not look orig (the cap).


The 330 resistor comes off the bias supply diode to a 10uf section of the cap.

then a 3.3k resistor goes from that point to the second section a 50uf. This section is tied to the 3rd section a 20uf (so 70uf total).

from the 70uf total junction it goes to the V1 photo multilplier tube (blk stripe), and to 33k power resistor on a term strip (brw stripe). Che can is connected to a term strip that is rivuted to the chassis (not solderd just rivut). Per the can its a 50/20/10 350v on all POS can.
