COUPLING TRANSFORMER 600:365 OHMS

These will probably find the most use in soundcard-to-ham transceiver interfaces. But I bought them to use as audio inductors in L-C filters. The TCTX-16 measures at about 2.2 Henries with a Q of 15 at 1000Hz with both windings in series. The TCTX-17 is about 2.9 Henries with a Q of 12. The Q is not high, but it is much higher than using power chokes with Q = 2 to 5. Both appear to have gapped cores so they would be useful as tuned plate loads in a c.w. regen receiver. A useful item at a cheap price.
