Russian tubes if I ever saw them.
Follow Ups:
There are many incarnations of this Russian 5Y3 type
The boxes look like the genuine plain Mullard boxes that can be bought from Langrex . The tubes on the other hand... Any ideas who did all those dodgy reprints ? I believe it was someone in the US about ten years ago . I still see these 'Mullards' on Ebay . Some selling for top dollar

Way back in the 80s when I first started collecting tubes, I saw lots of Russian and Chinese rebranded Mullard, RCA, GE, whatever. It was in that time period when most NOS tube stocks were depleted and the remaining tube dealers like IEC Servicemaster who were probably the worst offenders, would happily sell you Matched quads of Russian or Chinese EL34 Mullards in the correct box but with painted on labeling. They would also cross reference any tube in the substitution book and sell it as the one you wanted. stuff like 5691 or 6188 would be painted on a Sylvania 6sl7 and sold as such.
Getting back to the problem at hand, It is my opinion that during those "lean years" when only Russian and Chinese tubes were available as new, many tubes were rebranded by Mullard and sold as made in UK when it should have said otherwise. I don't imagine they thought they were doing anything bad and thankfully such practices are no longer tolerated. It is unfortunate that these tubes are still rearing their ugly little heads. So, do you due diligence before you hit that "buy" button! cheers, Dak

Buy Chinese. Bury freedom.
These particular tubes and many fake Mullard prints was handiwork from Hong Kong.
I have seen other Servicemaster International, Russian made, "Made in England" labeled tubes.At $60 each, quite a bit more than you can buy an NOS 5Z4.

is a bit of a pretender.If he really was the expert he says he is he would not be selling 6881/6su7 as equal to the 5691. The 5691 draws twice the heater current therefore they are not equals/direct replacements.
He also would not be selling 5687 as equal to the 7044. They are similar but the mu of the 5687 is 17 and the 7044 is 21. The plate curves are different, therefore the optimal operating points are not the same.
Just because everyone else is doing it doesn't make it right for a true expert to do it.
A true expert should be above that type of behavior.
A true expert should take the time to explain the differences not falsely claim that two tubes, that are not equal, are equal.
Edit, One more example.
"THESE 6SU7 TUBES ARE A DIRECT REPLACEMENT FOR ANY 6SL7 / 6SL7GT / 5691 / VT-299 /ECC35"
"DID YOU KNOW THESE CAN BE TURNED INTO 12AX7 TUBES WITH AN ADAPTER"
How in the hell can an adapter turn a tube with a mu of 70 into a tube with a mu of 100?
I don't expect statements like that from a true expert.

That's a bummer I picked up a quad of really beautiful NOS Tung Sol 6SU7s some years ago. I was told that it was just Tung Sols peculiar naming and that they were exactly equal to the 6SL7! I still don't have an application for them so I thought I would sell them at some point. Do some people use them as 6SL7s?
Steve
They are 6SL7s. Just really nice ones. Tre was talking about 5691s and 6SL7s not being the same.
They are really nice and I'll take half of whatever Mechans gives you. :-)

The 6su7 is a 6sl7 with higher vacuum and low noise and matched triodes.
I have 3 tung sols, rebranded, that I bought off ebay when no one else recognized what they were.
The seller was calling them 6sl7s.

Hi Tre, it seems that there are a quite a few incidents where mil-spec tubes were relabeled to the civilian designation. Many years back on the bay, a seller was liquidating 6V6 tubes that were actually 5992s. I scooped up a bunch of them and they were not that cheap but they are worth a whole lot more now. They came in nice original Bendix boxes stamped 6v6gt on the end flaps. I surmise that in the tail end of the tube manufacturing business when the production had shutdown and the wharehouses were selling off their remaining stock. Relabeling milspec tubes as civilian types was not unusual. cheers, Dak
....IME, those rectifiers are not very rugged. They won't survive 5Y3 apps let alone GZ32 or 5V4.
"We sell 200,000 tubes per month. We have a combined 165 years experience among the 4 owners. we have 13 stores worldwide. Let me ask you
Would you be wanting to bet the disk was only made in Russia. Then why do these tubes has vintage mullard English bases? .
By the way . One of the owners was there. Do you know who DeForest is?? He is the grandfather of one of our owners.
I myself worked for western electric KC for 18 years .
So would you bet your life on it? These are not made in England.
Where do you think Russia got the design from?
Do me a favor prove it.
Many people have been selling these disk English tubes as Russian. That's not proof. Really the only one that will have the facts. Are the people that were there at these factories.
You do know more then the average tube seller on eBay.
Really now. Think about it. How do you really know this for a fact.
Please elaborate! Love to know . There is a lot of wrong information and assumptions out there.

I got the same initial response, which prompted my post here.
Subsequently, I got a much more conciliatory response from a guy named Andy. He basically thanked me for watching their back, and indicated that the tubes were sold.
The original listing has been closed, so I have checked the completed Ebay listings and the original listing does not seem to appear there.
This seller has some interesting tubes form time to time, but they are generally priced out of my reach.
In any event, for as many tubes as they sell, they should know what is and is not a Russian tube.
I have had similar exchanges with this seller , to put it lightly , he is a narcissist . Looking at what he has advertised , probably destroying 200,000 tubes a month , having gazillions of tubes that no-one uses must take up a lot of space . I very much doubt he will get much interest , it looks very over priced too . £249 for 100 subminis for push to talk sets ? I think I'll pass...

I have never seen a "disk" getter holder on a tube other than Russian.
Has anyone?
I have also never seen a Mullard tube without an etched date code.
He doesn't say that the tubes are Mullard made but he does say they are Mullard bases.
Has anyone ever seen a tube not made by Mullard using Mullard bases?
I haven't but I haven't seen everything.
Don't all Mullard bases have a hole in the bottom of the keyway?

noted as being from Russia (on the tube and/or the box).
I recall the brand as "Edison", or something like that (Google didn't bring them up).

Let's see if he does.
Who knows? Maybe he can teach us something.

If these are truly British made tubes?
There were other tube factories in England besides the Philips/Mullard plants. Notable I know the Brimar stuff was made in eEngland but had no acid etched codes
Brimar did use codes but in a different format to Mullard and not on later UK production
Al
Stu, weren't Brimar GZ32s coke bottles? Don't think I've ever seen a Brimar or Mullard GT-shaped GZ32.The tubes for sale are prolly closer to 5Z4 specs.
