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
