Gu50 Set ?

pwan · 22nd April 2007, 03:47 PM

Hi,

I'd search myself but found very few schematic of GU50 Single ended in TIRODE mode. I wonder if any one can advise me more options of GU50 SET?

Thanks a lot!

Running curves from the LS50 data sheet, 400V anode 80ma current 4k OPT seemed very nice. 3rd harmonic distortion minima occurred here. The one Russian GU50 triode curve Ive found doesnt quite match up.

Datasheet limit values for triode connection are 400V across the anode and 80ma.

4K/400V/80ma with fixed bias loadline drawn on LS50 data.
