A B&K CR-30 Matsushita rejuvenator adapter using a GO7 neck board.

I just completed this. Unfortunately, I did not have an extra neck board for a Matsushita but I have a bunch of GO7 neck boards and also an extra B&K adapter that I could use for the plug end. Not wanting to order anything or spend any money, I figured I would see what I could come up with. Here's the results:

This worked great and only took about an hour to make. I could probably make another in 20 mins now that I know what to do. I should note that using the GO7 neck was a little tricky. It will not mate up at all with the Matsushita without being modified first. This is because the Matsushita neck is keyed differently to prevent something like this as it has a different pinout. To get around this, I carefully dremeled out pins 3 and 13 of the GO7 neck board connector. Now it fits perfectly on the Matsushita tube. The next trick was to open up the GO7 connector and remove terminal 11 and place it in terminal 4's slot which is not used on a GO7 (terminal 11 is not used by the matsushita). Opening up the connector required the dremel again to grind off the plastic weld points. Super Glue holds it back together again. From there it is just following the pinout Ken Layton suplied me with.

The Matsushita monitor I need this adapter for is for my personal PPII (one of my all time favorites!). I have wanted to do this for a long time but never made the time. Well, that PPII monitor really needed this. All three guns had almost ZERO emissions. Now the emissions are right where they should be and the monitor looks incredible. I knew it would look better after a clean and balance but I had no idea how much it would improve. This was well worth the time... I just wish I would have made it sooner.
 
Nice! I kinda wish I would have went this route because I took the neck board off my spare, but non-working, Matsushita monitor to make the adapter. I think only 1 of my guns had any life in it, but all 3 are solid now and the picture is pretty damn good.

I know this is an old thread but could you possibly share the pinout of your adapter? There seems to be a few different available pinouts on the web.

Thank you
His adapter is wired exactly as indicated by B&K, I posted this picture in your other thread.
Since he used an original plug you can use the color code of the wires and match up to the CRT socket.
