'North American shipping only - no international shipping '
Selling Qty-4 SED 6550C that are unused spares. I came by these when I purchased an Audio amplifier on Audiogon about a year ago and the seller provided them as spares NOS NIB. I have tested them on a Mighty Mite Sencore Tube tester to ensure there are no shorts and to confirm Emissions and Grid Leakage are to specification and can confirm they are all good. Since they have not been out of the boxes until recently I also tested them sonically in my amplifier and can confirm they sound wonderful without any noise, hisses, pops or microphonics. Please contact me for any additional information and/or if other testing is desired. The only reason for selling is I do not need spares as I no longer need 6550 in my system and they are sitting idle so I hope someone can enjoy these hard to find tubes. Photos show one example for a reference of one tube under test to show testing process to confirm there are no tube shorts and that Emissions (incl. life test ref. finger on life test button) and Grid leakage are good. Top scale on Sencore screen measures Emissions and lower scale measures Grid Leakage. I am listing these as 8/10 only because I have installed them in my amplifier for sonic testing and in my tube tester to confirm performance as best I can with the equipment I have. Date codes are 06XX.
