Interesting Projector set.

[Eric H]

Seller claims it's from 1955.

Man that rig is spooky lookin. Reminds me of the equipment you'd see in those crappy 50's Sci-Fi movies!

You would have to update your breaker box just to fire this baby up! Not the most attractive thing to have in your living room but still neat anyway.

What the hey were they aiming to project on? The side of the Empire State Bldg? The Moon? <grin> -Sandy G.

This thing could really piss off the neighbors! HHHHMMMMMM! That is if you choose to play it on the side of their house.

I bet that's NOT a 40kv supply. Probbably more like 80 - 100kv (!)

RCA made some REAL bizzaro looking tubes back then to deal with the issues of flashover at those voltages.

I'm amazed the seller's selling it with no warnings - this thing's pretty honk'n dangerous! the HV will kill, there's X ray dangers, etc etc etc.

I wouldn't want anything to do with it!

Looks like Marvin the Martian's space demodulator

although the unit would probably seal my fate, I would LOVE just to own that thing

[Sandy G]

Shit, fire that thaing up & it would dim TVA...Or at least make the Steam Plant out here chug pretty good....<grin>-Sandy G

The projected image will probably leave a dent.

That unit on ebay is the big brother to RCA's TLS86A projector from 1948, which used a 5TP4 operating at just under 30KV. The 5AZP4 came out in early mid- 1950s, and had improved phosphors and could be operated up to 40KV. If I did not already have the TLS86A, I would prebably be chasing after it, as I love projection sets almost as much as early color.

Where, exactly does the beam come out? It looks like some of those wires would be in the way. Are these regular NTSC sets with standard scan rates?

[John Folsom]

The light comes out the front. The CRT and wires do get in the way, but all they cause is a reduction in brightness and resolustio, as they are not in tehe folca plane. Much like a speck of dust on a camera lense, which does not show up in the photograph, but if tehe lense gets dirty enough, brightness and resolution of the photograph will suffer. Ah, the magic of optics.
