Does anyone recognize this tube tester? I am starting to repair a Brunswick BJ-6836 that belonged to my grandparents. Some tubes where missing but a couple of the tubes where still in it. This tube tester belonged to my grandpa on the other side of the family. I was pretty surprised when it actually powered up and tested a couple 6SK7 as good. Now I realize a tube tester only really can only prove a tube is bad not prove its good. But hey it did not cost me anything. I would like to test the 6U5 "eye" tube but the chart does not include any settings for it. Im hoping to find updated charts for it.

I cant find any sort of brand name or model number on it anywhere. The only number I can find is engraved on it like a serial number. AK324RB

You would have found one like that in a pharmacy or hardware store back around the late 50's to maybe the early 70's. There was usually a cabinet beneath them that actually was used as storage for the more popular tubes. Cool find!

Maybe if you look for a 6G5 which essentially the same tube on the chart you may find it. I know for a fact that some tube charts have the settings for a 6G5 and not the 6U5.

Don't think there are sockets for the old big pin tubes like the eye tube would use, six pin.

Ah you are correct. Still would be nice to find any additional information out about it. At some point someone stuck a small piece of paper with a dozen more settings on the face plate. That piece of paper has 11169 on one corner and M96 on the other corner. I also have seen Model 96 mentioned on the edge of the roll chart. But no brand. I do not recognize the Diamond shape logo with the oval in it.

Can you post a picture of the meter, that could give us more information.

There are no identifying marks on the meter. Most testers I have found online that are "drug store" testers and not professional electronics tech gear seem to normally only indicate good or bad. This has a scale with the corresponding "good" number listed on the chart.

Not sure if it might be some sort of local brand or company who made them. It came from the Milwaukee Wisconsin area (United States). Since this was long before the internet I doubt it traveled all that much.

There probably won't be any more modern chart than 6-72. If the 11169 on the update means 1/11/69 then those numbers may already be on the larger chart and if so you could remove the update. Does the chart pull out? Maybe there's a maker's name at the top?

Anko Mfg. Co. made tube testers in Milwaukee in the 1950s. That logo might be read as an A and an O.
