Power tube plate voltage in a MkIV?

[JOEY B.]

Does anyone know the plate voltage of a MkIV in full power mode? The negative bias voltage of the outer sockets in triode would also be helpful. I have some SED winged "C" EL34's (tubestore with a 33mA rating) that came with a MkIV and was wondering how well they would fare in the C+ with its high plate voltage and -46V bias. :?:

do you have a good Cat III muiltmeter?

I sold the MkIV a while back outfitted with STR-440 6L6's and kept the spare EL-34's. So, I was just trying to do some number crunching to see if these tubes will work in the C+.

The 561140 should put out 460-465 volts to the plates.
