Little Dot Tube Amps: Vacuum Tube Rolling Guide

  Any comment on later Sylvania 6SNTGTBs?
 
They look similar to earlier ones...but...the "chrome dome" is smaller, for sure.
 
I just picked up a "tested good" pair for $7...figure it was worth a shot.
 
I'll stick with these and the TS Mouse Ears, for now, for preliminary testing with my 6SN7/C3G adapter plate.
 

 
For $7 you can't go wrong! :)
 
When purchasing 6SN7, I try to stick to the 1940's and very early 1950's, as I think they sound slightly better. So if you really like these GTBs, you might want to try some earlier ones later.

The Tung Sols appear to be '49s, so it should make for a decent contrast.

Total noob here when it comes to tubes. I would appreciate opinions on these:

http://www.ebay.co.uk/itm/251789963059?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

and whether they're a decent upgrade from the standard Little Dot 1+ tubes?

I listen to pretty most music genres but I probably favour classical and electronic at a push.

Thanks in advance.

I am not familiar with the Svetlana version of this tube, but the Voskhod is a favorite. However, I believe the Ei (Yugoslavia) 6HM5 is significantly better

Thanks for your reply gibosi; I'll take a good look at those links.

I've also been looking at these, which may well be to my taste, after reading the guide at the beginning of the thread:

http://www.ebay.co.uk/itm/M8100-CV4010-5654-MULLARD-VINTAGE-MATCHED-PAIR-VALVE-TUBES-SQUARE-GETTER-/261733284625?pt=UK_Sound_Vision_Valves_Vacuum_Tubes&hash=item3cf084fb11

Is there anyway of telling whether the advertised tubes are indeed matching pairs and from the dates advertised without actually buying them?

Many thanks

Personally, I would skip the EF95 family, other than the 6HM5/6HA5/6HQ5...IMHO.
 
If you like the "Mullard sound", have a look at EF91/8083 or EF92/8161 (or even CV131).
 
I would +1 what gibosi said though...grab some Yugo 6HM5s or maybe try these (I like them a lot):

Also, there is no need for "matched tubes" on the Little Dots...As long as you are using same make/type, you should be GTG.

I've been rolling these Mullard 8083s tonight...Probably up there with the GE 6HQ5s, for me, so far.  They deliver a little less on the bottom end...but...they are very revealing...very smooth.

Hey Guys...I received one of my Tung Sol (nee Rad Tel) Mouse Ears 6SN7GTs today.  I was just wondering how they came to have zero getter flash/clear glass???
 
I won't have a chance to run it for awhile...still waiting on the 2nd one and the sockets from China...but...it tests good (84) on my simple Pacific tube tester (assuming the numbers from it are legit!)...with no shorts, and good gas reading.  The black body has no markings printed on it, and the glass only has the 6SN7 over GT from what I can see.
