2 output transformers in 1 amp?

[PeteMcK]

This may be silly, but here goes....

Is it possible to use 2 separate output transformers at the output of a push-pull amp, 1 on either side of the HT centre tap?

I'm thinking of converting a small stereo amp with single ended output stages to a more powerful mono amp
(guitar use, so linearity isn't that important)

Cheers,

Yep, secondaries in parallel so the trannies share the flux, I think...

You can probably even go class AB (be sure your OPTs are rated for max DC current), I'm not sure.

Hi,

You can probably even go class AB (be sure your OPTs are rated for max DC current), I'm not sure.

On the primary side the current is divided over the 2 windings,the secondary is combined in a // way so that the 2 16 Ohm windings give a 8 Ohm output and so on.

Should work.
