I tried that errant pair of Sylvania's. One channel was a bit more prominent or maybe it was psychological because I knew they were different tubes. After a while, that didn't bother me too much. Xcalibur, you are right, the Chrome Dome GT is a very nice sounding tube - more resolving with greater inner detail than the NU Black Glass, I had in their place before. Piano notes are more vivid and more right and female vocals have that lilt to them which was engaging although not as warm as the NU's. Trumpet and sax were extended with the right amount of bite but smooth and not edgy - at least so far on the material I heard. I am going to switch the tubes around to see if the channel prominence reverses.
 
I will try to hunt for GTA's/ GT's to make up a pair for the "not true" Chrome Dome. Does these links have the right tubes?

(Seller says date codes are [size=10pt]Bendix - 312 4-52, Philco - 318 53-49, Sylvania - 448)[/size]
 
[size=10pt]As for the "true" Chrome Dome, do I presume that it will match a GT with the short base where the tube construction is clearly shown above the top of the base, with a heavy getter flashing although not full like the one I have, a chalky capsule shaped mica with or without teeth? See links below:[/size]

I would personally buy tubes with test results.
"Tests Good" doesn't mean much to me.
 
Lori (greengirl613) is a first class seller, and will look after you if anything goes wrong.

Ditto that on Lori.  And her prices are very fair.

 

[Skylab]

I too have had only very good experiences with her. Highly recommended seller.

 

[musicman59]

Where can she be found?

 

[dminches]

Could you guys help me a bit?
 
Which one of those is better ? It is going to be my first tube so that's why they are not the pricey ones. If any of those twice aren't good then could you recommend me any other for max 30 $?
[size=x-small][size=small]6SN7GT Tung-Sol Short bottle clear glass [/size][/size]
[size=x-small][size=small]  Clear glass tube with square plates[/size][/size]
 
[size=x-small][size=small]6SN7GT Tung-Sol clear glass
  Clear glass tube with round mica spacers (mouse ears) at top[/size][/size]
 

 

[rosgr63]

The mouse ears Tung Sol is an excellent tube for me and one of my favorites.
 
Ask if the base has a crack as they often do.

If they're both t-plate then they'll sound exactly the same.  I'd get which ever one is in better condition.

I'd been wondering about that seller.  Test results are often printed in Gm but the values always seemed off (way too high) to me so I had been cautious.  She must have a tester that reads on its own proprietary scale.

I am also pleased with the chromedomes, this is the pair I got in recently:
 

 
They are in NOS condition, and both micas appear to be shiny.
 
I haven't made a full evaluation yet, but paired with the GEC 6AS7G and my PSVANE 274B they sound quite nice through the HD800. I need to switch the Treasures back in to be certain, but my early impression is that they are quite good at getting out of the way. There seems to be another level of transparency available, but as I said some variables need to be worked out as I am also breaking in a new usb-spdif converter.

I am not sure what scale she is using.  However, everything I have gotten from her has been well matched and the gms have been strong as compared to similar tubes.

Now you and Xcalibur255 have got me curious... just what scale IS she using? Perhaps, one of you will ask.

 

[mikey8811]

Xcalibur, one seller has reported that the micas, while capsule shaped and with teeth are "[size=10pt]semi clear that I can see thru". The date codes on these GTA's are [/size][size=medium]3/26 and 3/39.[/size]
 
Would they match Tube 1 ie. the "not true" Chrome Dome?
