CCCP was the band Russia was in before they broke up. Like the Beatles.

Ahh lol!

 

But the box said that they were London, England?

The box is nice and is worth a penny or two.

As for the tube, try it and find out.

 

There is a lot of miss marking in tubes, best go by what you see.

The flying saucer style getter is a give away.

Right. Don't ever believe the box. The tube itself is what matters, and that tube is unquestionably Russian, you can buy those NIB/NOS for under $5 each with ease.

Just received a pair of Tung Sol 7236. However, one of the tubes seem to have developed what seems like rust around the edges of the base. Have attached some pics of the 'rust' below.

Is this normal with such tubes or should I request for an exchange?

You can get such marks/spots in metal based tubes.

If it matches in values the other tube I wouldn't bother.

 

With Flitz paste they will come out nicely and the metal will shine like new.

Look like the plating is flaking and polish might make it worse but you need to get the loose particles off from it.

John is right.

 

First you need to remove loose particles.

Then you can try and polish a small area and see what it looks like.

 

Avoid the markings.

Quick question regarding Sylvania 6SN7s: I got some "regular" ones with my WA22, marked GTB. I also had separately purchased some "coin-base" ones which are also marked GTB type. The construction of both looks the same to my untrained eye. Other than the shape of the base is there any other difference?

post #2609 of 4081
Not that I am aware of, no. But I like the look of the coin-base ones!

Thanks, and so do I, so do I! And they may add an interesting contrast to the other tubes depending on one's setup.
