These are a pair of Siemens-Halske (RCA Labeled) 6DJ8 or ECC88 tubes. These tubes are one of the best in this family I've heard. They get you close to an Amperex 6DJ8 Bugle Boy D-Getter, IMO.
I bought these tubes not too long ago from Andy, Vintage Tube Service. Those who know Andy knows that he is probably the most thorough tester out there. He knows his tubes. He knows 6922/6DJ8's very well and he knows how to test and match these. I ordered the lowest microphonics testing category.
From his site:
"For those who have been around this tube for 30 years or so the exceptional qualities of S & H Frame Grid tubes are well known. As with the Dutch, the Germans worked well with the .00029 inch grid wire and other requirements of this tube. The good, early true S&H 6DJ8, 6922, 7308, have the highest transparency of any ever made plus more liquid than the Telefunken. For many the only contact with Siemens tubes has been the 1980 - 1990's Siemens–Rohr junk that is laying around everywhere, VTS avoids these like the plague."
I used them in a phono stage for about 20-30 hours.
Shipping depends on location, probably like 8-10 bucks (will need insurance).
250 for the pair. Buyer pays PP fees.
