OK some progress, wired up the power supply and tested it under various conditions to see how it performs. It was from the UKVRRR forum so no proper specs.
I am tending to run the boards at 230 Volts DC and each board so far HT wise is taking:-
Vision IF 24.5 mA. Timebase 26 mA. Tuner 24.3 mA
So need to get a series resistor to drop some Volt. The 6.3 V heaters draw is now at 3.3 Amps.
Now no laughing at this woodwork, but I need to keep things together, so tuner Vision IF and Timebase boards at least held together for now.
