This may be homemade. It had a bad solder joint at the collector on one transistor. Working good now. Traded for this years ago for a Prez Jackson I had nothing in, got it DOA as a throw in.

Any idea what BTL means on the switch? I'm looking into adding bias next. A good regulated circuit. I've used it on SSB and got good reports but I don't know how well it sounds myself. Definitely needs a cap on the relay.

Haven't got around to the bias circuit yet, getting other projects done first. I did try it out on side band and got good reports.
