Got an RCA G2000 and a "salesman sample" RCA today

[Electronic M]

So today I picked up an RCA 2000 off of Craigslist.

The set was in a rural building that used to be an RCA dealership and probably is the previous owners home. The set was complete with the correct remote, hang tag and the sales and technical books, and also came with a spare chassis that had the velvet bag (full of knobs) that the remotes came in...The seller told me he sold 6 of the 2000 new out of that shop. While I was there I also bought an RCA 11" monochrome table set (the one that people on ebay mistakenly claim is a salesman sample) that appears to be an unsold display set(and a 7" electrostatic silvertone I plan to use as parts for an identical set). The little RCA he apparently would put on the floor in the empty space left whenever he sold a console to get a "What's that?" Reaction from customers.

The RCA 2000 works but has dynamic convergence issues and had a noisy picture from the DTV box feeding it (which he claimed was the antenna, but I know better). There's no battery in the remote so I need to figure out the voltage to test it at, and try and source the right battery.
Tomorrow I plan to variac the little RCA and start trying to combine the 7" electrostatic set with the one I got from Kamakiri years s ago.
I'm probably going to loan my Zenith Avanti to a friend and put the RCA 2000 where it was.
