Figured I'd better make at least SOME use of the 3 17" B/W TVs that I incorrectly bought.... at least one went to CKONG.
One of the others went on to become my Guinea pig for my new 2005

I ran through all the steps in testing AND rejuvenating using the manual I found on Andreas' (thanks !) website
www.andysarcade.deI found this manual much easier to use than the one for the BMR-80. It is clearly written with less words while still being effective.
I went through the entire process much more quick because of this. Oh and the manual is in various languages, incl. Dutch.
All the first tests showed the tube was in nice shape. I also did a life expectancy test (over 2 years of TV use = 10 years home arcade use I'd say...). I also made a little spread-sheet with Numbers on my iPad and with just one click had it made a nice diagram for the condition of the gun. I'll extend this and publish it here so everyone can use it. Just have to enter some numbers and you get three nice graphs to compare

Of course, even though it didn't NEED any rejuvenating, I was still very curious because HERE is the difference between the non CPRU and CPRU Müters....and I needed to know if it worked at all of course...
I only had to select rejuvenate, select between soft and strong (first did soft of course) and then hit the start button. A red LED lit on the tester and the fireworks in the neck started... the scales were going up and down and finally came to a rest, his was looking good too

After a while (actually a lot longer than I have been rejuvenating with the BMR-80) the LED extinguished and the process was done. After letting it run in emission test for 10 minutes as suggested by the manual, the tube seemed to have suffered barely from the process. So I thought what the heck and do a Strong rejuvenation after that.
The only thing that improved was the curve, it got a bit flatter which is supposed to be better, but again, I would have NEVER rejuvenated this very tube normally.
I tested the CRT back in the TV and it looked great. (Snow only, there are no analogue TV transmitters anymore in The Netherlands
All in all, I am very happy I bought this one, it made an already great instrument close to perfect...
I have plans on doing a step by step video and maybe STILL write a new manual in English because I have a feeling it can be done even more efficiently....whatever you do with these devices FOLLOW EACH INSTRUCTION IN THE MANUAL step by step...that's the only way to get a test result you can trust.....
