Lamp limiter

[Mike Watterson]

For a moment I though Mike Watterson was making a "death cable" with a 13A plug on each end.  I think I did something similar to Mike's rig many years ago when I used a 1kW heater as ballast for some kind of discharge lamp.

Where would the lamp and the radio plug in? It's a rubberised trailing socket, but with a very short mains lead. So one plug and two sockets. It's still a bit evil.
I don't do old TVs, not since about 1972. I've not even seen one in real life since then. So I've only resorted to the "limiter" once. It was for the HMV 1507.
https://www.radiomuseum.org/r/hismasters_1507.html There is a veneer version. One of the few radios I've bought at an Irish auction. There was a big collection. Some stranger saw me puzzling over the HMV 1507.
"It's a radiogram! Open the back!"
It was still erratic but not blowing fuses when I put it in the vintage radio store part of the attic. I meant to use two cheap ceramic cartridges, one with 78 and other with microgroove by cutting off the tabs and casing in thin black plastic. It uses a huge isolation transformer for the pickup as the chassis is live, but the deck / arm is sort of earthed. Strange 3 pole mains plug on the side. The last photo shows the audio in transformer.
Someone sent photos of the dual cartridge (often missing and usually dead). About 1/2 down scroll list. Seems a mad idea compared to a flip over needle. Perhaps different compliance and sensitivity. A flip-over needle may be a compromise solution? Some early 1950s models used two interchangeable heads, one "docked" on the other rear corner (one Pye and one Pilot I know).
