I had a quad of the '75 "grails". It's a nice tube, just depends on system matching and sonic preferences. I found it to be very detailed, clear and transparent. More of a "solid state" squeaky clean sound imho.

Since I moved to the Telefunken G73R's, my former #1 Telefunken ECC801S's (matched pair) are now available in the Classifieds. Great deal.
PM me.

My testing standard for tubes is the behavior in a microphone circuit, so far most stable among the ECC88 series are the older Reflector tubes up until 75', while with most samples of Amperex \ Telefunken \ Valvo - I'm getting higher noise floor and random noises - this is due to lower input resistance and current leaks,

If shameless plugs are allowed here
Got a matched pair of NOS Reflector 6N23P 75' SWGP Silver shields - tested strong and noise free - open to reasonable offers

I recently bought my first tube amp (Schiit Folkvangr) several months ago. I have been reading about the 6922, 7308, and 6DJ8 tubes that are installed in the Schiit. One tube I keep coming back to is the Tesla Cross Swords blue tip built in factory 32. Recently I came across a red tip variant of the Tesla with Cross Swords. I am looking for a warm tube and not that sounds like a solid state amp. Will the Tesla blue tip provide a warm sound? Thanks in advance.

If you seek a warmer sound then Amperex, Mullard, Philips Holland are all safe bets I think.

I think none of my Eastern European tubes have a “warm” sound. Voskhod, Reflektor and Tesla are all more SS-ish.

Thanks for the input. I recently changed out the stock tubes which were two different brands due to a static noise when turning the volume knob, it could only be heard when no music was playing. I installed some Amperex 6DJ8 / ECC88 that I purchased on Ebay for $42 for the pair. The static noise is no longer present and I have about 20 hours on these tubes. Any thought on these tubes?

That looks like late 60s / early 70s A frame construction type, I confess I haven't heard that type before but you can read some info about it here: https://www.audioasylum.com/audio/faq/joes-tubes.html#6DJ8

Those are quite nice. I have ‘rolled’ them in Liquid Platinum, Woo WA2, Woo WA3.

Those are quite nice.

Agreed, I rolled some in the past and recalled liking them, but Amperex is my definitely my preferred tube for this type so I like the Amperex house sound.

Having recently picked up a VAC preamp that takes the 6DJ8 and 12 DJ8 families of tubes, I was pointed to this thread, which has been very helpful in getting started (and maybe ended, having picked pairs of Philips Holland and Reflektor 6N23P 1975 tubes).. One question I’ve had for reference, Was the evaluation of tubes done entirely with headphones or were loudspeakers involved too? The latter seem to be mentioned in the system presentation, but the write-ups for the tubes only refer to headphones. Thanks,

Came across these interesting E88CC tubes. Labelled as AEG but construction is clearly of the Telefunken... diamond stamp at the bottom and 45 degree slanted getter post. I couldn't find any date mark unfortunately.

Woohoo!! Out went the JJ 6922s, in went a pair of ....

How does everyone store their tubes? I have cigar boxes and others with a bunch of tubes in foam, box, bubble wrap, pairs in elastic bands, etc... What a mess. When I was a kid there were large square compartment type on the tube testing machines. I can't seem to find anything suitable and was wondering what others where doing.

Thanks.

I say store your tubes like a pro:
