Hmm.. 100mA for the pair; Maybe 3300V-3400V?

If so, you should not be short on modulating power ;)

Question is, how do you deal with the large DC voltage difference across the mod xfmr? is this not a risk?


nice.

Hey, do some calculating... That's -70V bias on the 250TH's, resting at 100mA of idle current.

Yes, the rig is -on the air- in that shot... That's also about 300mA on the final, and the final is running around 1500vdc at that time, I think...

regardless, for 250TH's with -70v of bias, to have 'em rest at 100mA... how much plate voltage do you think was on the modulators, at that time?
