This is the match for the top left tube:
Total cost for the pair: $12. eBay was looking the other way... Very happy
For example:
The first pic is from a lot of 5 6SN7s I bought for $35. These two tubes are both black glass NUs, that sell for $70 to $90 a pair. All were reported as 'test good'. A great deal.
The second two are a Ken Rad VT231 and a grey glass Sylvania VT231 I picked up from an estate auction for $15. A great deal... And fun finding a match for each on the cheap!
It is important for everyone to know that very good deals are out there. Perhaps not all NOS tubes, but still testing 'good'....
Sorry...think I got the postings the wrong way round!
Anyway, MMMan, your examples (and gibosi's...not to mention mordy's results after patient searches) have shown that 6SN7s
can be found for reasonable money...which brings me to an update on my suggestion to the Feliks-Audio Espressivo-E people, in Poland, to consider changing those mediocre tubes for 6SN7 drivers and 6AS7G/6080 powers...AND THEY'RE GOING TO BUILD A PROTOTYPE!! ...WOWEE!...If they can manage to keep the price below the LD MK9 and LaFigaro 339, that should be a giant killer to say the least!!
.
Will keep y'all posted...
Mordy,
I too am curious how the Sylvania 7963 and the Sylvania 5687WA compare in your rig. In my LD+, they are very, very close.
Well, gibosi, I can see why you love the 5687...I have only just finished cobbling together (much against my usual principles, lol!
) your (and mordy's) "flying" monstrosities...my excuse being I needed to make sure they would be OK in my new Little Bear!
Given that the amp hasn't many hours on it, and the tubes/masses of wires even less...plus only my HD598s to test (until I patch into my 650s), to say I'm VERY impressed is understating things at the very least
. With one of my GEC 6AS7Gs in the hot seat, I am fairly confident already that this cheapie chappie will almost be a match for the LD III & IV with modded upgrades. And for less than $200 (free shipping), this is quite ridiculous!!
I am sure the 5687s are a major help here...although I was very UNDERwhelmed by their appearance (especially compared to the C3Gs!), I can tell already that they are all you say they are...EXCELLENT. The full potential is a ways off yet...but I am getting really excited at the prospect of what may come, after proper burn-in/proper (silver-wired!) adapters/650s in tow
.
And then will come the shoot-out with the fully-loaded LD...can't wait lol!
