hey Poinz,
The new production is octal. Reportedly it is made by the same folks who did the later production for the European market. What I like is the KT90-big 50Watt plate dissipation. If I weren't getting such good results from Thoriated Tungsten, I would have long since gotten a few quads ov them...
6k6 a-a, 400V B+, 30% U-L, and 125 mA idle ought to make one sweet amp!
cheers,
Douglas
