I replaced my OA2 regulators and nothing's changed. I now believe that I blew my 6x4wa rectifier with my hookup error since I'm seeing AC plate voltages at the rectifier socket, but no plate voltages at any other tube sockets or any voltage readings at the other test points in the amp circuit. I have a nice NOS 6x4 replacement on the way, but I want to make sure that the voltages at the rectifier pins are correct before I risk blowing my new tube. Can anyone help me out a bit? I'm not exactly sure how to interpret the voltage readings I just took at the rectifier socket because I'm not exactly sure how the two plates are supposed to relate to one another and to ground.
Pin 1 -- plate 1 -- 360vac referenced to ground
Pin 6 -- plate 2 -- 95vac refrenced to ground
Between the two plates, I read 630vac, which is identical to what is coming off the secondary of my PT
On the PCB, Drip has written 380v above the rectifier socket, although I'm not sure what that's supposed to mean, exactly--maybe that's the rectified DCV?
Drip seems to indicate that I should be getting between 500vac and 600vac off the PT secondary--it's unclear to me whether my voltage reading is too high, right off the bat, and that it might be causing the problem in the first place (I'm reading 630vac off the PT secondary). For what it's worth, I'm also pulling a high reading off the secondary of my heater supply PT secondary (12vac, where it ought to be 10vac), and the heater supply seems to be working perfectly.
In short, can anybody help me and confirm that the plate voltages at my rectifier are within an acceptable range? Am I probably safe to just try it out when my new 6x4 arrives? Thanks a ton!
