Why Don't Local Audio Dealers Provide Tube Testing Services When They Sell Tube Gear?


For over 40 years I have supported my local audio dealers. I gladly pay more for their expertise and service. Some of my dealers have a store front, and some work out of their home. In either case, I always support them.

I have an "all tube" system, with 19 tubes, including my DAC, Preamp and Amp. Most of my tubes are NOS, and I like to "roll" many tubes. When I need to test a tube, or want ensure that the tubes I've purchased are indeed a "matched pair," I would really love to depend on my local dealer(s) to provide that service. 

For the most part, I have been very fortunate to buy NOS tubes from reputable dealers. Not always though. And when you are buying hard-to-find expensive NOS tubes, you sometimes have to take your chances.

At a minimum, audio equipment dealers should be able to provide "on-site" testing for the tube equipment they sell. Ideally, equipment dealers should be able to do "on site" testing of other tubes as well.

If a local dealer were able to service my audio tube testing requirements, I would seek them out for any new equipment purchases (including non-tube gear). That's part of having a mutually beneficial dealer/customer relationship.
Getting (and maintaining) good testing equipment isn't cheep, but it seems like a good business decision for maintaining and attracting new customers?

No new tube tester available, relatively speaking.

People who need tubes tested are as rare as collectors of ww1 memorabilia, or thereabouts.

Probably not going to be much in the way of even basic tube testing going on, at most dealers. I’ve got a B&K 707 in minty shape, but I went out of my way to pick it up almost 30 years ago, when they were much easier to come by.

Went and checked on eBay, seems like a lot of good testers still coming up for sale, but with commensurate rarity pricing. They can be sensitive to needing service and service intervals, so some limited tech skills might be needed if one is to keep a unit up and functional.

Most guitar shops sell tubes, but they don’t have tube testers, either.

Note that back in the day, you had to go to a tube testing place or location, as most did not have tube testing hardware, even when tubes where the norm. Now that tubes are relatively as rare as aforementioned WW1 memorabilia, it makes no sense to think that tube testing hardware would be more common then back in the tube heyday.

Moreover, I think that some are kinda cheap-ass, and would come to test their tubes, but buy elsewhere -like from the guy who has no tube tester, as the tubes are cheaper there. And view the tube testing gear in the one guy’s shop...as akin to some sort of public bathroom. They would be drawn to it.

Which leads down the road to abuse of the dealer and the tube testing hardware. Think it through. Humans and lowest common denominators, is what usually happens.
