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?
73 = Best Regards,
