Vacuum Tube Snake Oil Salesmen


Just a mini rant to complain about vacuum tube suppliers (not all but most) and their false advertising.

I ordered a set of 4 matched 2A3 Acme tubes direct from PSVane for my Woo Audio WA33 as an upgrade. They cost close to $1k all together.

When I got them I checked on my MaxiMatcher2. The boxes said 65mA but with correct operating voltage and bias set on the tester I could only get 2 of them up to 43mA. One other read 39mA. And the last one was an internal fault short which could have damaged my amp had I not checked them.

I asked to return one "Matched" set for replacement. The PSVane customer service would only offer to send me one tube and not a matched pair. They would not pay return shipping to return one set. Instead they demanded I smash the bad tube and send them a picture. Has anyone ever smashed a large vacuum tube with a hammer and seen where all the pieces of glass fly to? I said no way. I will throw it out or return it but I am not going to risk cutting my hand doing that. So they refused to send a replacement. 

While I had the Maximatcher out I decided to go thru some other tubes I had in my spares box to check them (purchased before I had the tube tester). I could not believe the results. Some tubes matched by well known vendors were off by as much as 30% from each other.

It is really a good investment to get a tube tester if you will be a regular user of tube amps. 

If you must buy PSVane then get them from Amazon and not direct so you have some safety to return them.

If you want to roll the dice with PSvane  by purchasing direct from the manufacturer, then that is not the best way to go. Others suggested purchasing from Amazon because of their Return policy. I gave up on PSvane tubes a few years ago because they did not have staying power. I switched over to Ray tubes and find them to be fantastic sounding and battleship build quality with a dealer network so you can return if there is an issue. 

Yes, I have had great experiences with Audio Research, Upscale Audio, and The Tube Store. I run around 50 tubes on my systems an they have been absolutely no trouble over the last ten years.  

It would be a real shame to turn anyone off of tubes because of a bad vendor.  I mistakenly stayed away from tube amps for few decades longer than I should have because of the over emphasized focus on occasional reliability issues. 

I think the private online sellers of Psvane tubes are really the problem.  At least that’s been my experience.  Buying direct from the Psvane online service center has not been a problem.  Again, that’s a least been my current experience.

I gave up on tube sellers. I never got what I was told I was buying. 

I have gone to Audio research for their "overpriced" matched sets (and they are painfully expensive) but each purchase was fully matched, tested, worked flawlessly and I was assured money back or replacement (entire) set if i was not satisfied. Yes it's painful. Yes it's worth it considering all the junk out there posing as NOS and matched.

Aren't Ray tubes just relabelled Psvane or other manufacturer like TAD and Groove Tubes do?

Although I expect they are tested and selected for the best of the bunch.
