anyone ordered the tube with Cryogenic treatment?
anyone bought tubes from upscale audio. what's the difference between Platinum grade and gold grade.
Yes, they can be removed, though it can be a bit of a PITA. I managed it by wiggling them to loosen them, and then carefully using needle nose pliers. That them up, but no harm done. No doubt there are other methods.
Use DeOxit Gold on the savers pins, mine come out without much issue.Thanks.
Anyone else?
The Platinum are quieter for very sensitive phono pre-amps. These are very sensitive to noise, as this signal gets amplified twice. Once by the preamp, then again by the amp stage. They also have tighter matching between sections. I bought the Gold, and they are fine noise wise. They were matched to within 6%, that's pretty tight.anyone bought tubes from upscale audio. what's the difference between Platinum grade and gold grade.

As for cryo treatment, I have bought many tubes from CryoSet and TubeWorld (Kuhl cyro) that were treated. They usually shortened the life of the tube ( I know the treatment is supposed to increase it - theoretically). I won't get any of my tubes cryo'd anymore because of this. On cables it's great...they last forever.
Maybe Pinkled could get one of the 3 pairs he ordered with the treatment to listen for a difference.
My experience with cyro sound wise, it kinda jumps ahead of the burnin process. In other words, straight out of the box, they do sound better, but after around 200 hours they sound about the same. I was just getting tubes failing way prematurely. CryoSet will cyro your tubes for like $8 a tube, if you send them in. I toyed with trying it with the Russians, then thought twice about it. I bought a lot of new production Russian and Czech tubes there - still have an almost new pair of EH gold pin 6922s with the Super Cyro treatment for sale on ebay - $25 for the pair.Thank Rb~ I wont get the cryo one.
yeah, I think i'm getting amperex 6922 and tele tubes...however, I can't hear until month from now, i'm in family vacation.
I have to wire me up a pair of those! If you know anyone selling them wired to plug and play let me know.
I threw a '74 SWGP Silver 6n23p into the mix tonight! Whoaa! Right there with the Tele E88CC!
