Hi guys!!

I have a pair of newly manufactured in a 1950s style SE output transformers. These are good old hand wound paper layered on 1940s-50s winding machines in the USA. They do a very good square wave and ramp. Nice interleaves for 40Khz before the a phase loop than flat to almost 100Khz. A 6550 triode wired at 70ma and 370V gives 5.5 watts to below 20hz. Excellent bandwidth and damping.

260.00 pr in the US only.

Here's some pictures, Like I said...they look like 1950s transformers. Endbells and pots are in the future.
