2 Vintage Matched
Tung-Sol
6550
Solid Grey Plate
Audio Tubes
Buyer gets both of the tubes in the photos. These tubes were tested in my Maxi Matcher 2 tester & a Hickok Cardmatic tester to make sure these were great. All the tests were excellent, exact match and both tubes test as new. Both of these tubes were made in the USA, by Tung-Sol, in 1960's. These are the solid grey plate, coke bottle version.
These are getting scarce and are a high end tube used by most of the professionals. Great for any audio amplifier. These tubes are what audiophile & guitar enthusiasts are looking for. The tubes will come in the new production (vintage replica) Tung-Sol boxes, as shown. These tubes are used, testing as NOS. Please view all the photos carefully, as they are a big part of the description of all vintage tubes. I will pack carefully & ship very quickly.
Tung-Sol codes: 3226028-3 & 3226104-3 (1960's)
