Best 6DJ8 tubes?

Colomor Electronics (UK) has an Ebay Store and still lists "grey pin E188CC 7308" tubes at $40/pair. Claim they were surplus military stock for Polaris subs. I bought a few pairs a while back and, while the acid etched code indicates 6DJ8 and not 7308 (and 7308s s/b gold pinned), they are Amperex Holland manufacture. Given the insane prices asked for vintage 6DJ8 family tubes, these may be a bargain. I've not used mine as I've moved on from gear with such tubes, but may sell them of in ten years to help fund retirement.

I use Orange label Amperex and Amperex Bugle Boys. Agree with Larryken - they are excellent.

I've tried Philips tubes, JJ, Sovtek and RCA. Now I have to say that the differences TO MY EARS (disclaimer: personal experience, no universal truth) are fairly small. I was lucky enough to stumble upon a Philips E288CC SQ. That is indeed the best sounding tube I have, but the difference with the standard E88CC from Philips is subtle. So don't start spending fortunes on very rare tubes - first try out the cheaper ones so you get a feeling of what you can achieve with tube rolling.

Go over to Audiocircle.com and check out electronic engineer Roger Modjeski's exposition about 6DJ8/6922 differences in the Music Reference section of postings. Basically, there is not any substantive difference. Depending on manufacturing tolerances, a batch of tubes can be labeled either 6DJ8 or 6922. Aural differences exist within this family of tubes of course, but don't focus on 6922/6dj8 as a factor of sonic differentiation.

Hi already have a Carver SDa490t in mint condition, I buy it in a dealer new one in 1992. Well I just fin a pair of Philips E88CC SQ special quality, not to expensive, with this tubes your Carver run magical ok, deep bass, excelents mids and extended highs, is just a dream, I put some acoustic parts inside the Carver and a nice foots, please put some rubbers on the tubes.
