Yes,
You would have to make a short conversion cable from 6.3 to 4-pin XLR. It won't bring something different than the 3 pin cable you are using now though. The 4 pin XLR is for balanced drive but it could have an advantage because of the low impedance when the 3 pin cable has only 3 wires in it. I reckon though that even the 6.3mm cable has 4 wires in it connected together in the 6.3 mm plug. You would be doing the same with the conversion cable. Theoretically (when the 6.3mm cable has 4 wires in it) that cable should perform better than the 4 pin XLR with a conversion cable.

The code for sylvania is 312 for the manufacturer follow this link..http://www.triodeel.com/eiacode.htm Hope it helps some. This does not cover all tubes however. This page has a lot of useful info also....http://www.triodeel.com/tubedata.htm Thanks I will check it out. The tubes am getting should be here Saturday. I think they might be 50's or early 60's. Last night I pulled a Sylvania 6SN7 from my tube amp. Green label. Great open sound and very clear as well. Made my HD800 still revealing, but without the treble bite.

ronzo56 have you tried the hd650's? I was wondering as you use the hd800's and wondered how they compare. Have looked at the 800's (with envy, I am sure!)but have not seen a comparison between the two. I am selling one pair of my 650's and maybe can take enough bottles back to make up the difference in price! Thanks.

I am selling one pair of my 650's and maybe can take enough bottles back to make up the difference in price! Thanks. Yes I have, but they are the older driver, had them for years, and they do sound a bit veiled IMHO definitely a darker sound but still good with the Ember. A comparison. They really are two different headphones. My particular pair of HD800's have drivers that don't have as much of the treble issues that have caused many to try mods. Most of the HD800's I have heard are very very revealing. You hear everything good and bad on the recording. They have to have a very good source which the Ember is and really IMO benefit from tubes in the circuit. The 650's are much more forgiving and tbh switching between the two I really hear the veil and dark signature of the 650's. They don't get much head time. The 800's are very clean and clear sounding with nice bass but not a lot of sub-bass it's there but balanced not lifted. I would suggest if you are thinking of an HD800 consider looking for a good used pair. Many owners seem to tire of them and sell them. Then buy another pair later. Most people I know here in California have done some version of the Anax mod on them. Best if you can listen to a pair first. They aren't for everyone.

Thank you for your input, this is about what I have read on the net, and I am looking at used as opposed to new. Don

It depends on when Jeremy has run out of Ember boards. The new batch will be made with the revised board.

Just to let you folks know, Jeremy has some 6SN7's for sale, they are not on his website, but email him to inquire as to what he has and pricing. Just bought a Ken-Rad VT231 6sn7gt black glass and a Chrome top sylvania from him, getting all geeked up waiting to hear the Ken-Rad. Lot of good things said about this one, best bass of the 6SN7 tubes is what I have been reading. Tubes have all been checked and knowing Jeremy is a reliable and honest business man should help put to rest questions on the tubes bought from him. Good Hunting.

Oh no! I'm in trouble now. Really hooked on this tube. Classical, acoustic, classic rock! With this tube there is a difference in manufacturer and era and type GTA, GTB etc. at least with the Ember.

Would also be interested in the price for a Ken-Rad VT231, I've just received my first VT231 Sylvania tube and it's a bit big isn't it ? looking forward to my adapter arriving so i can give it a listen ! What about 6F8G tubes, do they have the same fitment as the 6SN7/VT231 ?

Well, this is going to be short as I am busy playing as much music as I can, to finds as many varied and interesting pieces as I can, have had the Ken-Rad in for an hour now, and well what can I say, this is the most expensive tube I have owned. It was made in 1944, and the TOTAL sound from this amp is phenomenal! Orchestrations are bewildering, the amount of sound, the placement of instruments, the tone, the depth, is almost overwhelming. I had Wagner's Ride of the Valkyries on, and by time the end was near, I was ready to run outside to the barn, grab a horse and ride out into the night. Oh yeah, don't have a barn, horse and it is daylight! Talk about all encompassing, I am completely sold on this amp with the 6Sn7's now. I may die from hunger tonight as I don't want to leave the music. Over stated, may be but, I have bid on this Ken-Rads in the past, but when the bids hit $60 plus, I always dropped out. Jeremy had one and offered it to me, a little more than that, but because it was Jeremy, I trusted him, and figured if it was not all it was cracked up to be, I would stop the madness right here and now. I have couple of real nice sylvania VT 231's and a Tung-sol gt and a few RCA smoked glass and clear. I liked them all, the VT 231 the best. But now, wow, this Ken-Rad is everything that I have read. Did not think a new old tube would sound this much better, on Jeremy's tester, it was 88,89 90 was considered new, this thing is amazing. Only problem is, if it breaks, or dies, or is stolen, oh what will I do for music then. Good luck with the tube rolling, I am glad I kept at it. Found what I was looking for now.

In line with the 6SN7 "current" thoughts but to deviate slightly--I just got my Ember back with the SC added by Jeremy.
It works fine, however, it flashes several times before it stays on, even with tubes like a 6DJ8. Is this normal?
Also, my PS2 has started doing the same thing since Jeremy replaced the LM317 which died.
Cheers!
Edit--pardon the font size--don't know what's happening here

Definitely not normal. I am thinking the power supply may be to blame ? It may be having trouble with the higher inrush current ?
Contact Jeremy about it.
Playstation 2 ?

Finally got a chance to try the Chrome top sylvania I bought from Jeremy, another nice tube, try this video, starting at about 14 minutes in great distortion on this guitarist, for $20 or so this is solid buy.

Ron has two super early amps / silver board Ember His Ember supply was the one from the silverboard proto which was a GS18A series. We bumped the size up to a GS40A which is over double the output. Sending him a larger one to stop the flashing from happening And his Sunrise also is an early unit when we were using dual 4700uF caps in the PS section. With high current demand tubes, the powersupply stutters trying to start up. Sending him a pair of current 2200uF caps which will cure that prob
