Picked up a nice B&K 470 and made a CR-23 socket for it. Problem is, the WG 19K4606 I was going to try it out on is missing the tube model sticker, and so are two or three other 4600s I have lying around. I have also noticed the model stickers missing from a couple of other models. So the question is, how does one know where to set the heater voltage on the rejuvenator? If it helps, the resistance of the heater pins on the 4606 is 2.05 ohms, which includes 0.4 ohms resistance in the meter leads. The only problem with the tube is too much of one color and not enough of another, so the heater is not shorted. Any help appreciated.
 
6.3v and 50v is the standard for every arcade tube I have ever tested. these have included many 4600 series monitors as well as K7000, 4900, G07, U2000, U5000, Sanyo, Sharp, and many others.
 
All the 4600's use the same tube. The tube numbers are called out in the manual and schematics.

CR23, 6.3 volts, 50 volts
 
Thanks to both of you for the info. Ken, I made the CR-23 adapter after seeing your tips in another thread. Removed the socket from an extra neck board just to save space and used one of the spare connectors I have lying around, worked out great. Looking forward to trying it out.
