I've got an operator that gives me his unused tubes. Sometimes I get good ones....a lot of times I get garbage. I test them with the rejuvenator and trash them, or shelve them if they're still good. I've got one that isn't in my set up book. The tube number is #A63PNT14X. Anyone know what CR adapter this takes?

Thanks!

Hi
Apparently its from a Pentranic monitor chassis...model 1125 , thats what i have been able to find, aparently its chassis and tube base picture is here

looks like a CR-23, been unable to find a circuit diag so far with tube pins on, give the CR-23 a go, you know if it isnt the right base as alot of neons on the BK crt tester light up and no tube heaters!

There are actually quite a few adaptors that have that base, but I don't know of a single 25" arcade monitor that doesn't use either the CR23 or CR24. Either of these would have shown some signs of life with a CR23 adaptor. For future reference, the CR24 tube key would have to be removed in order to use the CR23 adaptor and two colors would be swapped but you would have gotten something on the meter.

Hi your quite right, there are a few with that same type of adaptor, CR-23 CR-26 CR-27 CR-28 CR-29 CR-41 CR-43 CR-44 and CR-45
 
use a meter on the tube base to determin tube heaters, its the only pins that give low ohms to each other, CR-23 is pins 9 and 10 CR-28 is pins 5 and 6

Thanks guys.....the heater matches up with a CR23. I'm thinking it's just dead. Wouldn't be the first operator tube I've seen be totally dead.

wack up the heater volts a bit, that can help get some emission going!
