For sale are four separate matched Sylvania 6SN7 GTB pairs. I bought them to use with a Schiit Freya, which I had ordered from the Headphone Bar, but after months of not shipping any product to their sole Canadian dealer, I was given a refund. I've since decided to hunt down another Ayre preamp (I need home theatre passthrough anyway).
The first three pairs were purchased from the excellent eBayer 'brhines2012' (who doesn't normally ship to Canada, so you won't be able to find any of his listings on ebay.ca). Each tube has undergone the following tests:
-Sound tested for noise and sound quality
-No shorts, gas, or grid leakage
-Rock solid bases and spotlessly clean pins
-Pins protected with a light coating of DeoxIT D100L to prevent corrision
Average 6SN7 new old stock mutual conductance is apparently Gm 3000/2600 on his tester. The test results for the following three pairs and their respective triodes are as follows:
1st pair, 1958: 3200 and 3350; 3200 and 3350 - $75
2nd pair, 1952: 3700 and 3550; 3650 and 3675 - $80
3rd pair, 1952: 3900 and 3800; 4000 and 3850 - $85
I also am selling a fourth pair for less which was purchased from another eBay seller (mjl4154), but I can't verify that that pair was tested by ear. They are from the 29th week of 1958, and were tested as being 109 and 106; 109 and 107. Price - $50. These do not come in a box, but will be packed well for shipping.
Thanks for looking.
