Seeking Valves

[Nowhere-Man]

Hello NM,

Nice to hear you eventually sorted this one- it was a bit of a marathon!

Thanks Chris, I just got a new grid bias resistor today as I want to get the output tube anode voltage up to spec. I think the grid will be a bit too positive as the bias resistor is 50 Ohms out of spec. First I'll test it that way and if the voltage is still at 245, I will lower that 1 K series resistor.

I'd be foolish to run it too long at too low a voltage but yes it does work fine now all the new valves are there.

Next project will be the 1939 Halycon.
