I bought one of these:
(http://jean-pierre.mbeck.ch/chronik_gross/3/Mueter_BMR80_gross.jpg)
I saw one at the recent German arcade party and talked about it with Speleo.
He suggested to search for this brand, and actually the "intelligent' version BMR-95
However, the prices I found were pretty high for those, and all in Germany. By doing some searching on Marktplaats I found one in Holland but it was this model, the BMR-80. This is a "manual" rejuvenator. Much like similar B&K rejuvenators.
For those who don't know what you can do with them: You can check the condition of CRTs with it and (if needed) you can rejuvenate ("renew") them.
Works on any B/W or color tube.
Will give it a test drive tonight on a "spare" tube (the burnt Ms.Pac Man tube)....
Only thing missing is the original manual but Speleo already mailed the German one (which is a bit hard to read because of all the translated terms, but I'll figure it out).
The one I bought was from a pretty old friendly guy who said he bought it when it was new (!) and did use it every now and then but that he was now mainly working on jukeboxes. Haven't checked it very thoroughly but what I saw is that it looks like BRAND NEW !

You should expect a lot of visitors from this community! ;D

It's easier to move that suitcase than moving a monitor, so I suggest a mobile rejuvenating service right across europe ;D
-
There of course will be a fee.
One Paul's 50's cab per rejuvenated CRT.
;D ;D ;D ;D ;D ;D ;D

Cool ;D
thank god you live in ridderkerk :wink:

yeah, here's mine! (https://www.dragonslairfans.com/smfor/index.php?topic=1977.0)
do you also need different adaptors for the individual models?
-
Yes I do,but they are probably not the same as the B&K's.
Forgot you had one. Pretty funny I got a German rejuvenator and you have a US built one.
I did also see a B&K 470 but that has only one meter (need to switch between the three color guns) which I didn't like.
The 467 is better because it also has 3 separate meters.
-
OK I played around a bit with a VERY gone tube (Ms.Pac's very burnt one).
The guns measured out pretty good still. Only the green was a bit weaker then the others. The Muter offers rejuvenation in 3 "levels". Tried clean first (just to play around, this tube is already written-off because if the burn-in). Didn't have any effect. Next tried the second level. Now the gun measured out MUCH worse than it was (I did like the micro-fireworks in the neck though ;D) . With the 3rd (highest) level I managed to get it back in the "good" range again, but the lesson learned (what I already knew): don't rejuvenate when not ABSOLUTELY necessary !
There's some calculations and graphs going on to fully measure the guns. I will create an excel sheet that will do the work (like creating the graphs for all 3 guns).
Wanted to test-drive another tube but had no luck. The tube is a A 51-211 X. The Muter table (thanks Speleo !) says I should use adapter 813. I've got it BUT the neck connector is of a different type. (For Speleo: it looks like the 803 connector).
I think I should be able to remove the connector to work straight on the pins, but still I found this a bit weird...
Stupid Hantarex ;)
Anyway, went through the entire manual and it's not hard to do, but you do have to know WHAT to do.
I'm happy that I already have the right adapter for the Amplifone tube (808). Not that I would even consider playing around with that one, but IF it will go bad in xx years......
-
I have a tube with a short (hantarex)from my vanguard
Can you help me :)
-
Yes yes of course !!! How about next wednesday evening ? Will be nice to actually use it for a change :)
-
Robin, please let me know the tube nr. so I can check if I have the right adapter...
-
Its from his zacc, so 99% change that its the Hantarex MTC900

I need the TUBE nr. my friend, not the monitor model.... ;D
-
:oops: my bad, thought they used the same tubes
-
AFAIR the Hantarex manual lists about 5 possible tubes.... ;D
-
Saint Nicolas is passed earlier this year
I have just one tube Hantarex very very tired, ideal for testing the device :D :D :D
I had 2 but I have broken one the other day ... shame on me :oops:

WHAT !?!?!?!? Shame on you ! ;D ;D ;D ;D ;D ;D Hey man it happens, there still are tubes left in the world.... ;)
As mentioned, Hantarex tubes don't exist. Hantarex is a monitor brand and they used various components from various manufacturers, among them several tube brands. Please look at the tube itself and see if you find a sticker with a number, usually starting with an A. Let me know that number so I can check if I have the right adapter...
I can check/rejuve it for you but you have to get it over here somehow...(and back)....
Maybe it is something for the Arcade Technical Party that has been running around in my mind.....which may happen in the future in the Arcade Capital of Europe.....
-
That won't be a problem for berny, he was in my place last week
That techie party sounds interesting...
Can i be part of that ? ;D
-
héhé Etienne!,And now i already know 90% of the way to the arcade capital of europe
my tube is itt A51-231X is a 19 or 20 inch?
neckboard hantarex HFB S4 - 1
To the other tube " shame on me " because I had my platine mtc900-e repaired and now the other party is broken :evil:

I found today a Nokia tv with a very nice (no burn) itt A51-231X tube , it's 20 inch
Lucky me :D
-
Andre do you have an foto of the adapter 813 ?
-
No....but I do now :)
(http://gallery.me.com/andre.huijts/100937/DSCF7520/web.jpg?ver=13214829210001)
(http://gallery.me.com/andre.huijts/100937/DSCF7519/web.jpg?ver=13214829740001)
For the record, I've got following adapters:
801
802
804
808
813
861
And one that is missing it's number. Would sure like to ID that one....so I took some more pics which I will post in the next posting...
-
Here's the one I need ID-ed.
If I have some time tomorrow I'll beep it through to see what connections it has. That should ID it for sure...

Bingo :D
I think it have the same connection as the 813
Your 813 is for my A51-211X have the 813 but have a red adapter instaled for use with your missing number adapter (pic later)
-
you mean the unidentified i think.. ;)
-
Pictures of my (short) A51-211X tube
-
YES i have a nice working spare A51-231X tube :P
-
YES i have a nice working spare A51-231X tube :P
I had one that worked well too, before I stupidly broke it,
Baahh, now I used as weights when I have to flatten something 8)
-
With a rounded tube face ?? ::) ::)
Anyway, yesterday evening Robin came'along and indeed it turned out that the pictured connector was the right one for that tube.
So, the one without label is also an 813 but with the different "Hantarex" connector....good to know ! :)
-
Well well....yes I said goodbye to my trusty and like new BMR-80. No, it wasn't that I didn't like it, quite the opposite in fact, I think it was one of the better toys to have in this hobby !!! Many tubes tested and some brought back to life ! The thing is also built like a tank. The craftsmanship is really perfect. I haven't seen insides of other rejuvenators like the C&K's but I've read people having trouble with them sometimes. If there's one thing I don't want is to be a rejuvenator/tester to be unreliable.....
HOWEVER, I started to like it so much that I went looking for gold.....I mean, the top-of-the range, best rejuvenator ever built this side of the ocean: The BMR-2005
Yes the year says when it was probably released. Pretty incredible to realize they built it around that time or even somewhat later.....of course, with the fall of the CRT TV, the demand for this costly piece of equipment (I think they cost a couple of thousand originally) disappeared.
SO they are pretty cheap to get now. Found one on e-bay Germany and my good friend Andreas was so kind to receive it and bring it to Eurocade...
Here it is:
(http://farm9.staticflickr.com/8437/7924221392_2c5ed125d3.jpg)
The biggest advantage of the 95 and the 2005 is that the rejuvenation process is done by a CPU so there is no room for making mistakes. With the BMR-80, the few rejuvenations that I have done went fine, but you have to watch for 3 possible things to happen with the meters when you should stop the process.
Again, the device is used mainly as a tester and only in a few instances to rejuvenate, but I thought it was worth it.
Can't wait to give it it's first test-drive...
The 2005 is on par with the Sencore CR7000 I believe. That one maybe nicer because of the LED bars instead of the meters, but I am not too sure about that, analogue meters do have their advantages in devices like this.
The 2005 can also do some extra things I haven't seen on any other rejuvenator, but I will have to toy around with that on a written-off (heavy burnt) CRT....
Anyway, if you have a tube you'd like to have tested and/or rejuvenated I can do it for a fair price, but I think shipping tubes is a costly and risky affair...
-
I have 2 MTC 900 Tubes that i would like to have tested.
One i am sure is good (it played again fine whole eurocade except for the whobbly image, but that is a chassis / fan problem)
the other i dont know, it came out of a zacc zaxxon but the guy mamed the cab, so i ended up with the leftovers ;D
I guess you only need the bare tube, no chassis right ?
Can drop it in the car and i pass the Arcade capital many times for work ;)
-
No problem of course !
Yes bare tube but it may be safer for the neck to transport the entire monitor....
The Tube/monitor on your CK looks great but you really need to fix that ventilator make it all wobbly, IMHO it ruins the gameplay, you have to time jumps very exactly on Kong games and that is very hard with a wobbly screen like that.
Get a new fan from one of your customers server racks ! ;);)
-
Yes i know, and maybe also a cap measurement / check while i am at it ;)
The reason i ask for the bare tube is that the other is now without the frame (tried to fit another monitor in it to mame the other cabinet)
So its bare now ;)
I can ofcourse install it in the frame again, the other project did not come through so the frame is empty.
Ill leave the chassis out then.
As for the fan........ ;D

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.de
I 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.....
