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.

Very funny answers. But imagine a young person maybe not too experienced with things smashing the tube and having glass fly up and hit them in the face or what if I am in a wheel chair or vision impaired? I am just saying that is a really bad policy for a manufacturer to take not knowing anything about their customer. OSHA would be all over this here in the USA. I sent them the photos of the tester and tube showing the internal short which should have been enough. But I think the point was missed that they would only send one replacement tube. Based on the deviation in specs I saw with their other products the chance it would be matched to the other tubes is very low. I usually order more than what I need and then match them myself once I get them because they are almost never matched properly. But these were a little expensive to do that. Business practice in China is to ship USA customers their shit tubes and keep the better ones for manufacturers and preferred customers. Just watch the recent video from Decware about tube supply. |
