REPLY:
There seems to be some confusion as to what specs apply. According to
http://frank.pocnet.net/sheets/018/g/GU74B.pdf
The max anode current is .75 A, not .5.
In any event, the tube specs are different from a 4CX800A, despite what RF Parts
spec sheet says. For one thing, the plate diss is only 600 watts, not 800.
