Red MacKay Posted April 15, 2021 Share Posted April 15, 2021 Double C cores. Very interesting. Might be a little more than the 10W you are looking for... Link to comment Share on other sites More sharing options...
Digital Man Posted April 15, 2021 Author Share Posted April 15, 2021 I need 15 watt, max, for the EL34’s, do you know any other specs for them ? There’s two of them, right ? Link to comment Share on other sites More sharing options...

There’s two of them, right ? This is all the info I have. Yes I have two. They are hooked up to a KT90 PP power amp. I believe the trannies are only good to about 12khz. The right pic is a 27kg (60lb) bass output tranny, fully balanced split bobbin. Yes you read correctly 27kg is possibly the largest output tranny ever constructed. This output tranny was constructed for experimental reasons. The Inductance was higher than the test equipment could accurately measure. The tranny is capable of delivering 1,000 Watts below 10Hz. However, the practical application is for 4 KT88s in push pull parallel 200 Watts. These large output trannys can be made available to valve enthusiasts who wish to have the ultimate active sub-bass valve amplifier.

Gremrock Posted February 19, 2022 Share Posted February 19, 2022 https://www.evatco.com.au/transformers/ These guys sell the Hammond transformers, I had a set in some amps, well priced and perform, not lundahl/tango level but a fraction of the cost Link to comment Share on other sites More sharing options...
Tax Posted February 25, 2022 Share Posted February 25, 2022 @Digital Man DM me with your what your upper price point is for OPT's with these specs. I may be able to help as I know a hoarder who may be willing to part with some of his stash but we only get one chance at an offer. Link to comment Share on other sites More sharing options...
