Recovered transformer 0-310v (200-250mA ???) - 7v 2A - Any idea ???

[kagliostro]

From a small Tube Linear Amplifier for RF I recovered a transformer (about 100-120W) with 0-310v and 7v 2A

I consider the 7v as a 6.3v winding, if it diden't drop by himself during function, a resistor will do the job

in the original schematic the 0-310v winding was used with a voltage doubler, but considering to use it with

a full bridge I think I'll obtain about ~430v for tube plates (I think that there are ~200mA disposable)

Any idea about the reuse of this transformer ?

Thanks

Heavy duty B+ but light weight filaments. Probably perfect for a one or two tube RF linear amp.

Yes

but something around 18W audio with which tubes ??

You may consider Mark Huss's Plexi 6V6. Three 12AX7s and two 6V6s. Filament current is 1.8A and the 6V6s can take the B+.

443v at node A !

That seems really perfect 

Grazie Steve

My plan failed

I received the transformer today

and it hasn't the specs I told

I referred the 310v (with doubler) and 7v to a model of Linear amplifier that used 1 x 6KD6 tube

but the donor linear of the transformer uses the same 1 x 6KD6 tube

but a 500v (no doubler) winding instead of 310v



So I think this thing will be usable only if I rewind it

Thanks for the idea

solution may be also that way
