Nicola what do you think of your Tung-Sol mouse ears?

 

[takezo]

any of the T-shaped black plates sound pretty darn good. the sylvania and raytheon
comes to mind.

 

[monsieurguzel]

I am looking into a pair of Sylvania 6SN7GT 1952 "bad boy" tubes and am a little confused. Some websites say that they need the 3 holes in the plates and others say that it is marketing and even the 2 hole ones sound the same. Does anybody know if this is true?

Sylvania indeed made a nice lot of 6sn7 tubes, i haven't heard a really bad sylvania...have heard quite harsh cheap chinese tubes though.

The tubes in the picture (above) are triangle, shaped (2 of them) and they have 5 holes with 2 ribs on the back of each of the 2 plates. If that helps.

I have seen the (tung Sol) Mickey Mouse ears on e bay recently pricey though.

I have never seen or heard of a Sylvania Mickey Mouse tube.

I dont'like Russian or Chinese tubes, but my friend use Chinese metal base say good tube.
This tubes is inexpensive but the sound is poor, hard, glass sound
7N7 is the good way, two adapters on ebay and good tubes from 10$, really there is no comparison

I search an 7N7 > 6SN7 adapter

Their are no 7N7 tubes on e bay for $10.00 unless I am blind,,Link?
OK there are 4 tubes no matched pairs. No tung sol.
No 7N7 tubes on audiogon at all. I would wait on the adapters,,LOL.

Thanks for the great info everyone. I just picked up a Darkvoice 336i and I've been doing a lot of searching today for 6SN7's and 6AS7's...Head-Fi, eBay, web... good stuff.

I think that I recall reading somewhere that the "w" designation is for low microphonics (e.g. 6SN7WGTA). Is that correct?

Regardless of whether the 2-hole tubes sound the same or not (and I can neither confirm nor deny this), only the 3-hole tubes are "Bad Boys".

I agree - I have yet to hear a Sylvania 6SN7 that sounded anything less than very, very good.

 

[KingStyles]

I have a tungsol black oval plate on the way for my driver tube. Is there any sound difference between it and the round plates that came before and after it?

 

[rosgr63]

There is also a Ken-Rad Black Glass Round Plates Oval Top with spacers.
Is it a rebranded Tung-Sol?
Has anybody heard this?

 

[KeeChoon]

I have some Sylvania 6SN7GTs that have staggered flat plates and date codes 7/13, 2/52, 1/26. The 2/52 and 1/26 have 5 holes on one side and 2 on the other side.

Are they rare?
