I would like to calculate an output audio transformer based on a R20 r-core.
However, I could not locate any data for it like core length, area etc.
One Japanese web site shows the physical dimensions only. Where can I find
the core properties and manufactures web sites?

Good luck to you.

** This page has all the dimensions, is in the USA and offer assistance.

** The core is GOSS, with saturation at about 1.6 T.

DC offset in the windings will not be tolerated well.

What sort of audio output tranny are you making ?

SET tube amp maybe ?

Then forget it.
