Grid-driven in AB1, c. 100w with a 200? grid swamper. Cathode-driven in
AB2, c. 350w - - depending on anode VDC. An 8170 or an 8171 in AB1 costs
about the same, takes up half as much chassis space, uses a simpler input
circuit than g-g config., drives with c. 150w, is less squirrelly, and
makes more steam.
have fun, Jack
