I have several friends running the YC-156/179 GG, cathode driven with
tuned input. With anode voltages of 5500 to 6500 they observe power
gains upwards of 19 dB. As you reduce the plate voltage drive
requirements go up but at the higher voltage, you can be VERY happy with
less than 100 Watts drive.
The YC-156/179 is far better than the 4-1000 both in performance and cleanliness of signal (on air comparisons). Of course you can't watch
the anode blush but the big gratification comes from other things ;)

Jim,
Grid drive I suppose? In GG I would guess with 200W drive
maybe 5-6 kW, or?
I?m planing to replace my 2x4-1000A?s with a YC-156, I think
it?s a ideal tube. As soon as I can get hold of a good one
at a decent price, would be a quick swap. However it will
be GG.
The 4-1000A is a pain in the rear end and I?m getting to old
to struggle with them.
