Audio driver transformers

Someone was selling small driver transformers recently. They are used
as speech amp driver coupling to PP modulator grids in small BA rigs ,
Thanks W4PQW

I gather you want output from a single-ended audio stage, driving a
push-pull pair with a CT secondary?

Since you don't need to sink the sort of current that you would with
plate modulation, you can get by with just about any small low-ratio
transformer that can handle the DC. Maybe even a cheap repeat coil.

Or am I off-base with this?

Check the site (something like) Dealamerica, and under the "Boatanchors"
section. There's a guy who's ad is dated in January with what you might
be looking for. Sorry I can give you the direct link.
