Vr5 *60 USA is the only markings I can find on them

The "VR5" is the valve type
Most are "VR 7 or 9" I have to look.
The "5" might be a JAN designation.....
That's the code that say's it's a 9 pin base and a 6.3V heater.... pretty sure.
Top line is a "Star" "7" "E"
"Star" is the New York Amperex factory
"7" is 1967
"E" is May
wow i should consider this. it seems to handy!
Hopefully this will help track one down... http://www.ehx.com/dealers Has a drop down list of world wide dealers. Are you Military?
Hey i tried looking within my area, they do not carry the sleeve sadly. However they do carry some amps :D! I should definitely check them out.
I can't express how much I love those little guys.
You can line up the pins easy.
You have much better control of the pressure applied to the tube when rocking them out and pressing them back in.
When you take a tube off the extender it, the extender, rocks out a bit. Important. press it back into place with your finger before inserting the tube into the extender. Do not align the extender with the tube.
I have had zero problems with these. No noise, what have you. In fact mine we 2nd's that tubemonger had at one time for $10 off.
Hey Fearless1 thank you for your advice !
With stock tubes I feel I just lose clarity and speed comparing to EF5, but there is amazing soundstage, separation of musical plans, something like 3D, more coherent image combined with amazing power on Lyr
Great to know you have been listening to EF5 and you can advice tubes that sound signature can bring Lyr closer to EF5 (I would stay with EF5 if it had more power, but for he4 it was just not enough and had to find something more powerful)
But from my first rolling experience I can tell tubes are critical in Lyr
btw. Is schiit crazy to leave no room to grip the tubes in order to swap them ???? they sit so deep, there is great possibility to damage tubes or sockets trying to remove tubes, I mean come on what is this ? crap for me, total crap ;(
Rocking the tubes back and forth to get them out is not very difficult. Show some restraint and you won't end up with shattered tubes.
that's how I do it ... :)
but you have to admit this is some kind of misunderstanding having in mind future tube rolling
I had many tube amps before and there were no problems at all
I don't see the misunderstanding. If you get the socket savers it makes rollin' even easier. However I had no difficulties rolling them without.
Maybe with Valhalla and Asgard having their second iterations, Lyr will iterate to an even easier rollable design.
Tape is your friend.
I discovered recently how handy this type of gardening glove is, for handling tubes -- when they fit the hand right, it's like a second skin, and they grip tubes so nicely. It's very easy to stay clear of the labels and still get a crazy amount of grip. Plus, your tubes stay clean.
