Valve equivalent or spec for Mullard YL1321
 

Hi,

Can anyone find the spec or equivalent for a mullard YL1321, looks like the same pinout as the
4cx250/350 family but conduction cooled. The main concern is the heater voltage, usually 6.3 or
26.5. I have tried the usual google etc and its not in any of my data books.

Thanks,


Steve H.
