I was rebuilding a small antique guitar amp from the early ‘50s, and found that they had substituted the case and thus the speaker, and thus the output xformer (because it was mounted to the speaker in this amp). I wondered if a different transformer would make a difference in the sound output level. The power tube is a single ended 6V6. Others indicated that this transformer should work for a 6V6, so I ordered it. I’m happy to say it works very well with my 6V6 circuit, with no modifications necessary. This xformer had a different primary winding resistance than the one that has been substituted. Since it did boost the output volume a bit, I think the 6v6 output tube had been trying to feed a mismatched transformer.

Since repairing old tube radios is just a wintertime hobby, I do not like to get much invested in it. I found this transformer to be a cost effective replacement for most of the 30s and early 40s radios. Performance is great.

This output transformer worked fine on a Majestic 1770 with a single 6K6 output tube.

Perfect for single ended el84. Dave Gillespie spec'd this into the Magnavox 8600 "flea amp" project (AudioKarma)

The perfect replacement and value for my HeathKit Mohawk RX-1 receiver!

Excellent supply of products & excellent service.

This output transformer was a great replacement for a 1930's Stromberg Carlson Model 61N which had an open primary. This model had a single 6F6 audio output tube.

Works great on old Philco 48-482 output.

Great little transformer I use them on 6aq5 and 6v6 tubes at 8 ohm and they work great but I think you could use them on a 50l6 at 4 ohms
