Selling Qty-4 SED 6550C that are unused spares. I came by these when I purchased an Audio amplifier on Audiogon and the seller provided them as NOS NIB. I have also tested these on a Mighty Mite Sencore Tube tester to ensure there are no shorts and to confirm Emissions and Grid Leakage. - 4th photo shows actual tube under test and that there are no tube shorts. - 5th photo shows Emissions leakage = "GOOD" - 6th photo shows Emissions leakage with 'life test' (ref my finger on life test button at bottom of photo) = "GOOD" - 7th photo shows Grid leakage = "GOOD"
