Title: CRT tester help!
Post by: Grauwulf on April 20, 2005, 11:30:15 pm: Does anyone out there have a CR-XA universal adapter for a BK Precision CRT tester? I'm trying to build a CR-31 and CR-23 adapter for my BK 470 tester, but I can't for the life of me figure out which wires go where. If someone has a CR-XA could you please map the wire colours and locations in the connector for me so I can cross reference to my adapter chart to make my adapters correctly?

Thanks a bunch!

Dandy Manufacturing Company
Dan Randall TV Service
2323 Gibson St.
Muskogee, Oklahoma 74403
Phone: 1-800-331-9658 or (918) 682-4286

Their unit comes with several universal sockets and it does projection tv tubes, too. It comes with a tube setup/cross reference chart also.

Ken> I really don't want to buy an adapter, I have all the componenets to make my own, I just need to know how to wire everything. I tried to map the wires from one of my other adapters, but I didn't have much luck.

Post by: menace on April 22, 2005, 07:32:08 am: ok--if I'm understanding you right you have the 470 pinout (i.e. what color wire has what function) but not the cr-23 pinout?

here's my thread:

http://forum.arcadecontrols.com/index.php?topic=35351.0

inside is the cr-23 pinout, the corresponding function of each pin on the crt and a link to the B&K manual showing what each wire on the 467/470 does--so between the two you can corss reference and make up the adapter.

Post by: Ken Layton on April 22, 2005, 11:43:25 am: For everyone's information, this is taken directly from the "FAQ" on bkprecision.com

"Do you still supply CRT adapters for your older rejuvenators?

Yes, B&K Precision's Parts and Documentation department sells 'CR' adapters and Set-up Charts for models 467 through the 490B".

So the oldest unit they provide adapters for is the 467 (30 years old). The 467 is still a great unit and I use mine all the time.

Post by: Grauwulf on April 22, 2005, 11:46:25 pm: I know what each wire on the CR-23 is supposed to do, what I do not know is what the pinout on the connector on the tester is. The 470 does not have the same connector for the adapters as the 466 does.
