Vintage 1960's, new old stock Harman Kardon XT3 mic transformer in original box. Primary is 600 ohm and secondary 50 K ohms. Line/line to grid - these are from the vacuum tube era!
Designed for use as microphone transformers but these make very nice moving coil step-up transformers for moving coil cartridges such as the Denon DL-103
They can also be used as input transformers for your vacuum tube amp projects. Add a pair of resistors across the secondary, ground the mid-point and now your front end is the phase splitter
The plugs on these fit rare-ish 9 pin sockets that have the same pin circle as an octal but for low level signals it is better to solder to the terminals directly. However, if you insist on sockets I can provide them at additional cost. Request a custom item.
Overall height - 2.25" Diameter - 1.25"
These are unused, in near perfect condition and in original boxes
