You seem to be a discerning consumer. Can I interest you in a Dumont (GE(c implied) dots of quality) 6as7? Tested a wee bit better than nos and very tightly matched. Any chance you are interested in wege high pricing?


Sarcasm aside this was the stock tube in my BHC kit. I have made some upgrades since then but this was the tube that got me hooked on vacuum tube amplification.

LOL! It's as hard to fake (a lack of) dots as it is a UFO getter, even for Bangy Bang and Wege_is_high_tubes.

I agree some vendors lack scruples, but it is likely the tubes are legal and legitimate
For tax reasons companies could legally claim "Made in X" simply by handling or re-boxing imported product

It is true that some tubes were marked with a different country than origin for tax purposes. Often imported tubes sold in Germany under German labels (Siemens as an example) were marked FOREIGN as country of origin.
Rebranders like Haltron and Zaerix used tubes from many sources, including GEC and Russian tubes, but the rebrander would never put on a name brand like Amperex or Sylvania on the tubes and boxes.
To sell a Russian made Svetlana tube with the inverted saucer getters as a Telefunken tube made in W Germany and giving the impression that you are buying a genuine Telefunken tube with the concomitant sky-high prices is not legitimate.
This current ad shows a Haltron Russian made 6AS7G, but it is advertised as a German Telefunken tube:

He’s definitely high on something.

Thanks for all your help...my Thomson just arrived. So far it's working fine, hoping it lasts a long time

Some help with TungSol 5998 codes please.
4 tubes all read 6648 under the JAN 5998 markings.
On the other side 3 read 6635 while one reads 6637.
Any ideas on what they mean?
Thanks

The date codes indicate a certain week in 1966, which suggests that they were all manufactured at about the same time. Why are there two date codes? My best guess (and again, this is just a guess) is that the vertical date codes indicate the date the tubes were first labeled and warehoused, awaiting shipment to a customer. At this point they could have been sold to almost any customer. But perhaps at a somewhat later date, the tubes were selected to be sold to the US military. They were pulled out of the warehouse, the JAN code was added and the date indicates when this happened.

In the end they were all manufactured at about the same time, and I suspect that the later date codes, 6648, would only have had meaning for government bean counters. But again, I'm just guessing.

Thanks for the explanation!
These appear to have flashing on the bottom, they seem different from others I have.

I have a pair of 5998 manufactured in 1968 and they have a halo getter above the top mica and another below the bottom mica. So check to see if yours have a halo getter on the bottom.

I just received a pair of WE 421A and one tube has double D getter on top, the other has a halo getter on top and a halo getter at the bottom as you described with your 5998. Both tubes have code 813.

Post up some pics. Looks like yours are from 1981. I also have a pair of 1980's WE 421A.

You are right, they are from 1981. I will post some pictures tomorrow.

Here are pictures of the WE 421A. Both have chrome top, the one on the left has flesh halo getter on top and bottom and the one on the right has double D getter on top

 

[leftside]

I also have a pair with 813 code. And also an even later pair from 1985 (these have the bottom getters). As stated above, these tubes could have been manufactured much earlier and simply "restamped" by WE. I'm not sure to be honest.

Posted WTB — looking for a power tube for this BHC w/ Speedball.

I’m hoping there’s someone out there with an orphan needing a good home.
