At 90mA you had better keep the plate voltage biased to 110V or under. That'll provide about 0.5W if you do so. That's non-optimal for all 45's, including the Vaic, by a long margin, unless I'm missing something interesting here when 0.5W will do. But 90mA is hard on the tube at any voltage.

- 45's in AES SE-1... what's a PP amp doing with the label SE-1? nt - Kurt Strain 23:03:48 05/12/02 (0)
- It's really SE. I guess they tie both cathodes together and bypass everything. nt - Kurt Strain 23:07:17 05/12/02 (0)
