For those of you who want to hear tube rolling options, these are available for the summer. Too hot in Florida, I go straight class D figuring less a/c is going to impact the sound in my room more than any benefit from 'tube sound'.
If more than a handful respond, I am open to dividing this into two groups. There is also a Melz that says 3/51 and a couple RCA's. And a Westinghouse. And 4 tung sols of unknown lineage. None of these besides maybe the Melz ( I don't know what year it is) are fancy tubes, most of these arrived with the Lyr 3 used,
I've wanted to do this for awhile, and if this puts out the fire in tube prices a little, I'm going to save many monies!
If need the amp, I suppose I could toss that in for those without.
A Tung Sol 1626 NIB NOS were $50 a pair (Hytron were under $40 NIB NOS, but Tung Sol is thought to sound better. I can't really tell but I stay on the safe side). A Lorenz ez81 were NIB NOS $40 a pair. A Sylvania 6189 NIB NOS is $43 a pair presently on eBay (closer match for $5 more, I don't need it as my monos have independent levels).
The Telefunken in my ValiGruven is more than all six. (it was included in the Mjolnir I bought used).
None of those pictures are Bad Boys. The mica structure is a give away that they are not. Bad Boy has rectangular mica with 3 slightly downward turning triangular spikes in each short side of the top mica. None are present on the left tube and the right tube is a round spiked mica.
How many tubes did the military use? There's a guy trying to sell marconi's for airfare to Vietnam I mean, come on. Can't I just fly to Hanoi and source it myself for five bux?
The plan was simply to try a new tube in my Lyr 3, casually, just something besides the JJ 6SN7 that came with it. Started looking for info on tubes and found this place. So naturally...
I've now received 10 of the tubes I've ordered on the way down the rabbit hole. This is fun. Question. Two of the tubes I ended up with are Tung-Sol 6SN7GTB, angled black T-plates, top D Getter. These seem well regarded, albeit not the most popular or sought after tubes. What I'm really wondering about though, is the branding. I haven't seen either of these mentioned here:
Thanks for the articles! It's definitely easy to drop some coin on this stuff... I feel pretty well set at this point though, thankfully. Like I said I've got about 10 tubes to play with and just acquiring them has been a fun learning experience in itself. I've tried the stock JJ 6SN7, a 1940s Raytheon 6SN7GT/VT-231, a 1957 Tung Sol 6SN7GTB, and currently a 1954 RCA 6SNGTA (which I think may be my favorite so far).
