3 in parallel, pi net. 1250 volts on the plates at about 300 ma gives about 300 watts out, 1200 watts pep.
They were going for something like $12.00 a tube new a while ago and I got a bunch of them for the 32v3's... The rig started out as a pair, and I just stuck another one in. I am really surprised at how well the rig works. The tubes laugh at 1250 volts, I have the ultra modulation circuit built in and even on very high peaks, nothing arcs. That is more then twice the recommended plate voltage with plate modulation...
