As you know from the thread where I'm testing the latest TV's I need to get an A51 580X on the tester. I was unable to ascertain what adapter I need as my testers data book did not have the tube listed.

I found online, a more comprehensive data chart covering many more CRT's, including the A51 580X, its now in the library. I need adapter CR-23, sods law plays out! I have almost all the adapters but you guessed it CR-23 is missing. Anyone here got one?

CR-27 and CR-31 seem to fit but from what I've found elsewhere online, I've no idea if the wiring is correct for an A51-580X. 

Model CR-27 Adapter: Tests color inline/delta types 370ELB22, 470HMB22,
670DB22, others

Model CR-31 Adapter: Tests color in-line types 320CSB22, 370KSB22,
370LGB22, others. Video arcade game monitors with 8 pin tubes.

Hi Chris,

I'll check for a "23" for you once I'm back home

Well as luck would have it I have in stock a new A51 580X CRT PCB socket (right of picture). I also had a spare fully populated duplicate adapter (left of picture).

I also found someone's CR-23 wiring diagram, armed with all this I might be able to make my own CR-23. However I'm a tad confused as to what to do with G1 red G2 red and G1 blue G2 blue? They appear floating!

I should have a base to fit if you get stuck, Malc.

OK I've think I've got this wiring sussed now. 

final23

I'll wire it all up tomorrow as doing it at this late our with tired eyes and mind, is a recipe for mistakes.

Hopefully I can give the poor old Grundig's tube a little help, amazed I had a CRT PCB socket in stock, all those years of e-bay stocking is now paying off.

The adapter was a success it works, the CRT however is another matter.

That's a shame....not even temporary success.
