Svetlana Tubes Winged C 6550 2001/2002 Date Codes NOS [Expired]


no longer for sale

I am selling most of my personal stock of Winged C NOS vacuum tubes.  This is the last of my 2001/2002 date code flat getter matched tubes.  After these, I will be selling only individual Winged C tubes from the 2001/2002 era both angled and flat getter.

This pair is mid-late 2001 and mid-late 2002 date coded, flat getter design.

Tube 1
Date Code 0233
Plate Current 76.2
Gm 6.07

Tube 2
Date Code 0137
Plate Current 79.7
Gm 6.16

This pair are tightly matched at 4% plate current and within 1.5%  transconductance [Gm] (please view pictures of the boxes).  Tested on my Maximatcher tube tester and double matched on my Orange tube tester (they test as 12/11 matched pair).  5% or less is considered "platinum" matched.

All of my Winged C 6550 tubes are NOS and as perfect as perfect can be!  All test brand new (as they are NOS), and have been stored in a temperature and humidity controlled storage room.  Please view the pictures.  These are simply sublime in every way. All were selected for me by the dealers for matching and top performance.

I am selling mine at about the same price for matched pair as many tube retailers are charging for new stock 6550 vacuum tubes.  Get these magnificent beauties while you can. 

My price is, for obvious reasons, not negotiable. 

I will pack securely with bubble wrap and packing peanuts and ship in the continental USA only via USPS priority shipping, insured, and signature required.  Shipping fee is $18.

PayPal fee is included in my listing price.

If any questions at all, please contact me at any time.  See my feedback and buy with confidence.
