How would you adapt the 7963 for the Lyr? Build adapters?

 

I have tall-bottle metal base and short-bottle black base 6SN7W's. In my opinion, the metal-base version has more bass slam whereas the short-bottle has better base detail. I also have several TS VT 231 Black Glass Round Plates, both round and oval micas. Of these, I prefer the short-bottle 6SN7W.

 

The easiest way is to use two 9-pin socket savers and some 18-gauge solid core wire. Cut 8 pieces of wire, about 1" long, and strip one-half. Insert the 7963's thin wire leads into the appropriate pin holes in the saver and use the pieces of 18-gauge wire as "push-in pins" to secure the leads. No soldering is required. :)

 

Pictures are worth a thousand words, so a look at Mordy's posting in the Little Dot forum shows just how easy it is. He is rolling a Raytheon 6832, but the pinout is the same as the 7963:

The rockgrotto site has a nice graphic showing the different pinout diagrams for the 6DJ8 and 7963. One has to remember that these pinout diagrams are drawn as if you are looking down on an upside down tube. Looking at the top of a 9-pin socket saver is the mirror image. So looking at the 7963 upside down, the pins/wire leads are numbered 1 - 8 in a clockwise fashion. Looking at your socket saver, for a 6DJ8, the pinholes are numbered 1 - 9 in a counter-clockwise fashion. The 7963 does not use pin 9, so you can simply leave it empty.

Edit: My avatar is a tall-bottle metal base Sylvania 6SN7W. The metal base split and I am using a "high-tech" twist tie to keep it in place. lol :)

Thanks will have to give it a try!

I found the sly tall metal base had very airy highs, and was very transparent, I liked short bottle 6sn7w as well. But for me it was the rich tonality of the TG roundies that made my ASL Hurricanes sound incredible. I also liked the Mullard cv1988 brown base and '55 sly tall boys. Mullard Ecc33s and coke bottle Ecc32s.

Have you ever tried the Russian 6sn7 equivalents?

Nice tube collection!

That was bringing back fond memories! Thinking of those great 6sn7s is like remincing about old college girlfriends! And I went to UofF - hotties galore!!

The Russian equiv is the 6N8S - even has the saucer getter - but at the bottom!

Pretty cheap, but they'll work.

Looking to pick up some holy grail voskhods soon now. 

They are certainly less fatiguing then the early 70s Telas I received yesterday. Very mellow sound and balanced. They have a very natural sound to them. Great buy anyone looking for a cheep solution to their tube rolling needs. 
Good to hear! Not bad for $20 bucks! Wait until you hear the better '70s, the differences aren't subtile. Btw - the 'Holy Grails' come as Reflektors as well as Voskhods (same construction).

Cheers! :-)

Yes, I have one of these, complete with the Russian pentagon, bottom saucer getter and dated VI-74. However, unlike 6N23P of that era, it is just average, not bad, but not great either.

Yes, I'm happy to hear you like the '74 Reflektors SWGP Silvers. I rank these #2, below the 'Holy Grails' and ahead of the '75 Voskhod Plate Post Gray Shields. It looks like you would agree with that ranking? Those '75 VR Plate Post Grays where the previous king of the Russian hill - now tied for #3.

I'm always excited to get others take on these. Especially someone who has three , including the '74 Grays, of the top 6n23ps. You're only missing the #1 'HG's.

Cheers my friend! :-)

If I manage to get an extra matched pair, I'll let you know. The '74 Silvers will get better as they settle in, as you already know I'm sure. They'll open up and get even sweeter, the detail will increase, and the sound stage will deepen and widen.

Thanks for the ranking feedback. :-)
