I've had 20 pairs Cryo'd by Moray James, one the originals in Cryoing audio gear and will offer them up here first for those that have the B-283 or it's siblings.
btw, we cryo'd (Moray calls it CryoGeneration and does it the way he has for over 20 years, manually) the whole B-283, took ages to break in and we thought we may have 'oops' it, as the soundstage had collapsed, but the bass was noticably tighter, so stuck with it (hooked up to the digital radio) and one day after about 4 months had the wow, thats different and nice experience. Sounds great.
With the 6J1's I found what I always find with cryo'd tubes is a blacker background for the soundstage to be painted on and a little less distortion or grain in the midrange. Nice upgrade IMO.
$30 pair shipped anywhere in NA, if you elsewhere PM me for a ship quote.
I'll be advertising this soon in all typical places.
Cheers,
Ian
