2 NOS TUNG SOL ROUND PLATE 6SN7GT BLACK GLASS 1940'S [Expired]


no longer for sale

2 Beautiful NOS special application grade TUNG SOL ROUND PLATE 6SN7GT. These are unused stock from a collection of industrial grade electronics I recently acquired. One tube is the oval mica variant, the other is the rarer round mica on top tube. Offering them together or separately. Having owned and listened to dozens of both of these over the years, I can tell you there isn't any difference in sound between the 2. Plates and grids are identical, just the top mica which only firms up the tube at top is different. Still you may have singles your matching or collecting a certain one etc.. So, price is 200 for one, or 400 for pair. Round mica tests: 2750/2875 Oval Mica tests: 2900/2900 on a calibrated Hickok 539C where 2550 is NOS and min good is 1640 They come in old white military boxes they were re-boxed in after testing. They have been listening tested in a high resolution system and sound excellent! Please DON'T BIN for one of these. Only BIN if buying BOTH. Please EMAIL if wanting just one. THANKS! Please see my other items for top quality tubes from this collection. Thanks for viewing.
