I recently got an x-can amp and have been looking around at different 6922 tubes. There are a ton on ebay that look like tubes people recommend (Mullard/Amperex etc.) but I have no idea how tell if they are genuine, if they are in fact good tubes, what exactly to look fo apart from brand names (i.e. gold pin, getter info...) etc. I was wondering whether anyone can recommend some eBay sellers who are reliable and have good stuff?
Also interested in recommendations for good 6922/ECC88 tubes.
