For those of you who has equipment that uses 5687/7044/7119 types, which ones are your favorites?I found that overall, the most pleasant sounding of the bunch are the Tung-Sol ribbed plate types (from the late 40's until 52 or so). The Tung Sol 50's type with the D getters are also very nice.
Surprisingly, the Sylvania 5687's are the next best bet. The difference between the GB and standard mil spec types are very little.
The 7044 is a very nice tube as well, but it's not as warm as the 5687. The GE seems a bit warmer (compared to the Sylvania), while the Sylvania seems neutral and clear sounding. Neither one sounds like the 5687.
The 7119 is harder to classify. It has more gain, which may not always work to the benefit of the application. It seems warmer than the 7044.
Lastly, the tubes that these are paired with play into the equation as well. With most KT88 types, the 7044 seems to really shine, while with 6550 types, the Tung Sols and Sylvania 5687 are magic.As always, YMMV.

Here-here for truly rich and detailed flat plate 5687 Tung-Sols !
I also have a pair labelled GE which are otherwise identical to the pair of NOS NIB Tungsols I miraculously just acquired.
Mind you the early 50's Blackplate Tung-Sols with horseshoe getter are very decent sounding, a little richer than the 80's JAN 5687B's, which are quite resolute and perhaps more neutral with great top end extension.
I've got some NOS Sylvania Gold Brand arriving soon, so I'm keen to see how they stack up....BTW, I use these tubes as drivers in my Silbatone JI-300B Mk.II.
You will really like the GB 5687 sound. Very smooth and detailed.
By the way, if your system sound could stand to gain from a slightly brighter signature, the 7119 may be just the ticket. Using the 7119 driving GE 6550A, a very detailed and open soundstage is presented. combine that with a Phillips or Amperex 6DJ8 preamp, one can obtain some excellent results.
I used one section of a single 5687 per channel in a simple linestage. Goldpoint volume control, Elma switch, wirewound plate/cathode resistors and MIT RTX coupling caps. It was a good sounding preamp but on a whim I decided to try the cheap Russian 6N6P since they are supposed to be quite similar.
Note - pin connections are different - 6N6P pins out like a 6922. I had to rewire my sockets to try these tubes tube.
In the end I really preferred the 6N6P (at least in my system). Less dark, it has more transparency and a 'faster' sound. To my ears it seems more neutral. For $5 a tube, its a heck of a steal.
Sounds like a good deal indeed.
See, I think to some extent, it depends how the tube is used in circuit. In the application I use, it's the driver and phase splitter feeding a pair of GE6550A per channel. The input is from the preamp (7308/6DJ8 Amperex).
I would think the 5687 is best suited as a driver tube, not necesscarily as a preamp (line stage) tube.
My buddy made a 15/20 watt integrated amp using old Dyna iron, with 5687 as the front end driving 6BQ5s, and that little guy kicks butt!! It's got a lot of drive for the power, and the 5687's sound great.
I have quite a collection of 5687s, but the early Tungsols have evaded my greedy grasp.

No need to be jealous. I'm sure you have a similar enjoyment factor...
I vote Tung Sol 5687 ribbed plate. I do not want anything else, so I have no second best.
I agree! However, they are very hard to come by. I only have the four I'm using in my amp right now. I've got a lot of the 2nd generation D getter types (from 53 until the late 50s). They are similar to the Sylvania of that era.
