RE: two questions about 45 and 300b..............thanks

BB,

I can get 3.5W's out of a 45 (ac heaters) and about 5-6W from a VT52 (Has to be DC heaters) and about 12W out of a 300B with DC heaters.

All of those are less than 0.25mvrms noise.

With AC heaters on a 300B the minimum using all the WE tricks was about 1.1mvrms or about 4x higher than DC.

I guess the best way is just try it and see if you can do better. VT52 has to be DC heaters to work it has higher filament voltage than a 300B.

Thanks,
Gordon
