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.

Ignorance is bliss. Sort of glad I don't have a tester, as I think there would be much anger within me from seeing the results.

Their customer service is literally pathetic. I'll never buy from them.

Thanks for the heads-up.

@thecarpathian - I've bought NOS from a very reputable dealer and when I put then in and turned them on, it sounded like gunshots, and I turned the amp off in a hurry. Sent them back, got another pair of the same kind, same thing happened, and I just got a refund. 

On the other hand, I've got Ray Reserve 6SN7's and put them in the same amp and no problems at all. 

I like NOS tubes as well, and have a number of them, but it's a bit inaccurate to imply that there would be no problems with them while avoiding fully tested and matched tubes like Ray Reserve. 

@marco1 +1 "private online sellers of …. tubes are really the problem."

I have good +++ experience buying tubes from https://peavey.com/product-category/accessories/misc/tubes/

I had issue w/ one tube of bunch short, and Peavey sales sent me new good tube immediately! 

Isn’t it the same golden-ears who routinely experience stunning improvements from rhodium fuses and $1000 Ethernet patch cables who also presumably run grossly out-of-spec tubes in their gear, yet notice nothing?

"I paid $1000 for a pair of EL84! They must be the best EL84s in the world! You get what you pay for!"

Indeed you do.

 

@thecarpathian 

I agree with your assessment of shopping with a reputable dealer... but NOS tend to be a world of deception. Emphasis must be on the reputable dealer. That I agree.
