Default FS: Audio Transformer Fire Sale

It's time to sell off parts from some old projects to raise money for some new ones.

All prices are reasonably firm and include PayPal fees. Shipping is extra. PM is fine, or email my user name at ecp.cc



Electra-Print plate loading choke.

An externally hosted image should be here but it no longer works. Please upload images instead of linking to them to prevent this.


These are 100H of inductance, M6 cores, and are gapped for 20mA -- slightly higher than their standard.

$75 for the pair.




Electra-Print phase splitter chokes

An externally hosted image should be here but it no longer works. Please upload images instead of linking to them to prevent this.


These are a little different than the standard fare. They are on 80% nickel cores as opposed to the 49% EP usually use. As such, they have about 2x the inductance of the regular ones. Additionally, they are not varnished meaning that you can restack the lams to play with different inductances. The more interleaving, the more inductance and the easier they are to drive, but the less linear they are. The less interleaved, the less inductance, the harder they are to drive, but the more linear they are. These are currently fully interleaved. Details on how to stack lams here intact audio and an example of how to use them here http://electra-print.com/docs/6bx7pp0001.pdf

$125 for the pair




Electra-Print line level push-pull output transformers

An externally hosted image should be here but it no longer works. Please upload images instead of linking to them to prevent this.


20K:600 line level push-pull output transformers gapped for about 15mA per side. Use them for 6H30, 6N6p, 5687, 7119, ECC99, etc in a preamp or differential DAC output stage.

$150 for the pair



Electra-Print Parafeed Headphone Output Transformers

An externally hosted image should be here but it no longer works. Please upload images instead of linking to them to prevent this.


Custom made 5K:32 2.5W output transformers. Use them with a CCS loaded tube, or use the above chokes for choke loading. Great for a L'espressivo type build.

$115 for the pair




Lundahl LL1517 line output transformers.

An externally hosted image should be here but it no longer works. Please upload images instead of linking to them to prevent this.

The TVC with switch, the Elma switch, the parafeed OPTs, and the push-pull line level transformers are still available.
