What to do with 10K OT?

[Phil_S]

That may be a tranny from an Electro-Voice A20C. Potted, light color paint? If so, it used 6v6 tubes, PP.

This is a black tranny, fully enclosed, with four mounting holes. The seller says it is from a Fisher 20-C receiver and was coupled with a pair of 6BQ5. There is a yellow stamp on the bottom: 539-117B Tec. Assuming the tube is correctly stated, this is a 10K OT. Size wise, it is surely in the 15-20W range and it might be good for 25W. I just didn't find anything about the unit it supposedly comes from, not that the lack of information would ever stop me from using it in a low power 6L6 5K application. I thought maybe some conversation about it might be worth having.
