Taken out from an old Technics receiver, has center tapped secondary of about 2x20VAC. Could someone estimate rougly the power of this device?
Thanks

What was the power output of the amplifier from which this transformer was taken?

That should provide an estimate of the transformer's rating.

IIRC it was 2x25W but delivered by a single STK4042 (or similat) mounted on a miserable heatsink...
Btw this trafo isn't so small, weights about 2kg
