Here is an LPB 6a Carrier Current Transmitter for someone, and oh by the way there is also a coupler listed:
It has been a very long time since I have seen one in such great shape.
Very nice.
I guess I should fess up that the LPB 6A on ebay is mine! I've been trying to reduce the mountains of equipment on the shelves in the basement, attic, and well, all over the house. Most of it is ham gear. I picked up the LPB several years ago thinking "you never know when you might want to try...." and I never did. And my station is pretty well established now and I'm not going to be messing around with other options, so out it goes. I've done zero work on it, and no more testing than mentioned in the listing. But it is super clean. I would expect it to possibly need caps down the road just due to age, but that's about it.

A very lucky radio guy is going to get that Transmitter.
You must have quite the collection Tim!
Something I have always done in the past on vintage radio's and transmitters is , take it apart, clean it and inspect. Write cap values down and start the process of obtaining those replacement parts.
Once that is all out of the way, fire it up for a smoke test. Those old parts dry up as you know, not following those steps can create a big headache.
Too bad you can't plug it into a standard AC outlet. It would be cool if it was that way. It could have more range than my Talking House V5.0 (iAM). And in a complex it would get you some listeners.
TheLegacy it IS possible to do carrier current on one standard AC outlet.
There is a link floating around to a carrier current tube transmitter that uses the AC cord to achieve carrier current, and the baby monitors used the AC cord to get the signal to receivers down the line.
When my carrier current equipment is repaired I'll do some tests using only a single branch of the AC service to see what happens.
The equipment on eBay now could easily be wired to feed a single AC outlet.
I'm not good at wireing up stuff like that. But if I had a carrier current transmitter that I could simply plug in and go that could work here. At least the buildings near me would have clear reception of my AM station. Also it would get over the noise level.
TheLegacy said: "I'm not good at wiring up stuff like that."
That is very wise because AC power is a killer and never forgives a slight slip-up.
Probably most manufacturers stand clear from selling carrier current products because of the danger to their customers.
If only fireworks makers were so cautious.
