[dsavitsk]

Developed for the Torpedo 3 headphone amplifier, these are available on their own, too.

Is there a datasheet available? I'm interested in the physical dimensions..

They are on EI-625 cores, and share the pinout with the Edcors of the same specs (also made for me 🙂 ) except that the tap on the Cinemag primary is a center tap, not a 7K tap.

Am i reading that right at 1.5"x1.8" inches? Cute little guys, and ideal for the project i have in mind. Do they fit the OPT PCB's you have in your store?

Cheers,

Yes. The PCBs were designed for these.

Nice to see more choice in transformers for headphones.

Still, would you have some measurements on how much better they are compared to the edcor ?

Any word on a re-stock? I'm kind of itching to get going on a Torpedo III.......
