Croft Series 4 PL519 regulator

[peterfarrow]

Does anyone have the Schematic/circuit diagram for the B+ regulators in a Croft series four, they use a PL519 ECC83 and an 85A2....

I have a ton of PL519 tubes and want to make a regulator to drive KT66 power amp output stage...

thanks..

I don't have the schematic. But i do suggest you take a look at this. Tube Based Voltage Regulators - Part 3

Beware that if you decide to built one of the said regulators, you must use insulated windings for the heater of the PL519.

kind regards

Yes I have been looking at that too, thanks

Can you not just give it it's own (dedicated, floating) heater supply?
