3A3 High Voltage Cup Part Numbers
Dose anyone have the RCA part number for these above chassis style 3A3 high voltage cups, or a generic industry equivalent? There must have been gazillions of sets that used basically this same cup. I've run across them by accident in the past, but now it escapes me where to even look.

IIRC Workman resold these. Someone must have an
old catalog & that would give you some numbers to start with. 73 Zeno:smoke: LFOD ! |
I think I have one or two that would work. If you need one let me know. Unless that one arced through somewhere it still looks usable (just not as pretty as new :D ) to me.

Sure it still works. I'm just trying to track down the RCA number, or possibly a sub for future reference. I can't find one on ebay for anything, which doesn't really surprise me because most folks that run across one wouldn't know what the heck it was for or what to call it. There has to be some laying around someplace. It's kind of like the elusive Zenith convergence cloverleaf.

I tried Googling "tube plate cap". Found this right away:
https://www.rfparts.com/tubes/tubes-platecaps.html There are three on the second page with different diameters, you should find what you need there. They're cheap too. |

I've got one here you can have for the cost of shipping. PM me if interested...

Maybe the guy Dubis7 could 3D print one from ABS or similar material.
In a pinch, make one from acrylic - one large cylinder, one base plate, and two standoffs, and a little MEK or epoxy. I have a plastics fab guy....:yes:.....I would just need rough dimensions, and the center to center on the tube socket screws.

They are identical in dimension, they just have that little angle in them which was necessary due to where they sit in the cage. If you don't mind the angle, I can send you that one since I don't really need it. http://videokarma.org/attachment.php...1&d=1487341271 |

I also ran across these Workman numbers last night on Ralph's Industrial Electronics, unfortunately without pictures so its a little difficult to decipher what they fit, but his prices look decent. http://www.ralphselectronics.com/Sea...est=%23%20Bolt |
