After a fair amount of deliberation I think I'm going to forego further work on the Hammond H1C 6V6 PPP monos I've been tinkering with. Instead, convert them to KT88 UL PSE monos based on Kegger schematics/circuits.
Basically, all the main bits of the H1Cs except the oil capacitor and OPT will be repurposed. The OPTs I will use are the Edcor 25W CSXE 2.5K:8. Have a pair of those on the shelf.
Values and circuit look like I've got them compiled into a schematic correctly?
The voltages are what's predicted by PSUD for 75mA on (each) KT88 and 8mA on the driver. But, I think it will need higher value for cathode resistors at this voltage, yes?
