Most people would rather give out their ATM pin than their favorite tube seller.
 
Ebay is a good place to look since there is a wide variety, but you you still try to get to know your sellers there.  Other than that, there are a handful of sellers, many of whom are mentioned here.  Upscale audio, vacuumtubes.net, audiotubes.com, tubeworld.com.

OK--LOL,
 
You forgot one

IMHO, at the absurd prices the GEC tubes go for you are better off getting some Chatham 6AS7 in their place unless you have a lot of money and a burning desire to spend it on tubes.  The Chathams are good sounding 6AS7s and still go pretty cheap if you patiently wait for the right deal to come along.

The Tung Sol 7236 is a completely different internal structure than its other brand relatives....looks (and sounds) nothing like the Sylvania and GE variants. The Sylvania and GE 7236 and 5998A are similar IMHO, with the 5998A suffering from more microphonics than the 7236. 5998 and 421....whole other game.

 
Conceded. I have Sylvania 5998A that look exactly like photos of the Sylvania 7236. If the Tung Sol 7236 and 5998A are both different from the Sylvania, that is understandable.
 
That being said, within each of the different 5998A / 7236 brands, I still see no benefit to spending more on the 7236. Seems that the TS 7236 is very rare though, which makes it a moot point.

The only reason I'd get one over the other is to have a higher probability of finding a quieter tube. I find the Sylvanias quieter than the GE and the TS quieter than both for 7236/5998A. From a construction perspective, the 6080WA made by TS seems to be the quietest of all of them. Do you have the speedball in your crack?

Yep, I have balls in my Crack. Several other upgrades as well.

Only tube noise I've ever had to deal with is a terribly microphonic driver tube, and a 5998 that pings as it warms and cools.

I've done some inspection of plates, as well as ear listening.  You and I agree.
 
The Sylvania 7236 is the same as the Sylvania 5998A, expect for the glass bottle.
 
The TS 7236 is the same as the TS 5998A, including the glass bottle.
 
The GE 5998A isn't a 7236 tube at all.

None of the 5998 are like the 5998A and the 7236. The standard 5998 is a different/superior tube.
 
But all of the 5998A and the 7236 are pretty much identical, save for the very minor variations between different manufacturers, and the computer rating on the 7236. The computer rating isn't something magical, except for the ability to hold the current to zero for long periods of time without degrading.
 
In any case, I maintain that the 7236 is probably not worth the price premium over the 5998A.

Woot. Placed more order for a TS 5998 and 7236 yesterday. Now comes the worst part.... I wait. :\

 

[GrindingThud]

I also put in an order for a TS7236.....shipped today.
@mike200, let us know how that 421 is with the speedball....

Mine just shipped today. I also won a pair of Tung-sol/Chatham 6as7gs on eBay. Not NOS but tested in the mid to high 90s. No complaints since it was only $10 shipped.

 

[GrindingThud]

Mine arrived. . Little bit of corrosion on the base, but otherwise a nice clean tube for $35. Tube sounds great being driven by 6cg7.

On the Russian tubes, is the 6N5C or 6N13C prefered?
