The 913 is a 1" electrostatic CRT. It looks like a metal 6L6 with a glass
end, IIRC.










(running an hiding to avoid flames)

OK This is an all glass, flat-end envelope. Not much larger than a 50C5,
but a bit larger. Coated, can't see inside.
Yikes! they actually used magnetic deflection. I was hoping for
electrostatic, but with 9 pins that may be difficult. Been too long to
remember how many electrodes are needed for grid, focus & any more anodes.
Leseee.
2 fil
1-cathode.
4- dif plates
1-focus
1- accel anode

That's 9......maybe you need more...Oops, forgot the grid. Make the cathode
common with one of the filament lines or make it directly heated.......Oh
well. If it needs coils it'll make a nice conversation piece.

If it is from a camcorder, it should have a deflection yoke. How
about some pictures? It might trigger someone to recognize it.

Also, you can lay small parts on a flatbed scanner, cover them with a
sheet of white paper, and put a light over the paper to reduce shadows.
Yo can get good close-ups this way. I usually scan at 600 DPI, and
reduce image size to what I want. I would post a picture, an ask the
guys on news:sci.electronics.repair if anyone there can identify it.

Take a look at this little cutie! ;-)

Many early systems used separate cameras and a suitcase
VCR. My RCA camera had a removable viewfinder which
used a minature CRT with a yoke.
