HTR-1005B-1S: Tired CRT and Looking for its Part Number

[rohmell]

Hi all,
I have a HTR-1005B-1S with a tired CRT, it takes a while to obtain a trace, and the intensity is low. All CRT and power supply voltages are in spec, so I would like to obtain a replacement CRT for it.

I know Huntron has discontinued support and parts for this unit, but does anyone know the part number for the CRT, or a cross-reference part number?

Yes, I know I could disassemble my unit and find out the CRT number for myself, but it is in daily, constant use, and I would like to minimize its downtime.

Thanks all.

What is the serial number of the unit? Different CRTs were used depending on when it was made.
Thanks.

Serial number is: 214 03221
Thanks.

According to part numbers, the CRT was a Toshiba P31. Can you verify this? Huntron still has them at $250.00 each (!).

P31 denotes the phosphor being used in the CRT

There should be a longer parts number for the CRT, such as 12ACP31, 3ADP31, 5BHP31, 8CP31.
Usually the first one or two digits indicate the heater voltage.
I will open 'er up and see if I can find the exact part number for my CRT.

The last MFG number I can find is 85DB31 from  Toshiba.

OK, Thanks for all of your help with finding the part number for me.
