Hi all

I am looking for mini pushpull audio output transformer , exactly like the
same type used in vintage transistor
portable radion in the 60 and 70's .

Does any one know good siurces for this ?

Thanks
EC

An example might be the Mouser/Xicon 42TL013, 1K center-tapped
primary, 8 ohm secondary.

There's a whole bunch on page 998 of the Mouser catalog.

My gut feeling is that these won't be available for a whole lot
longer, in fact I wonder why they're in the Mouser catalog, they
haven't been used in consumer equipment for more than a decade now.
But for replacement and the oddball case where you just need an audio
step-up or step-down transformer it's nice to have them available.
I've been known to use tiny off-the-shelf audio transformers in
production designs for pulse transformers.

If worse comes to worse, small AC power transformers make poor to
passable audio transformers (depending on standing DC current and core
saturation).

Thanks

Just what I am looking for .

Be Well
