6 NOS 6SG7GT/JAN-CNU NATIONAL UNION Tubes; Tested Removed From Sealed Carton!

Description

6 NOS/NIB 6SG7GT/JAN-CNU NATIONAL UNION Fully Tested Vacuum Tubes Removed From Sealed Carton!
These six (6) 6SG7 GT tubes are new NOS in their individual original boxes.
I have sold many sealed cartons of 100 ea. and have received only positive feedback.
I am listing these in lots of six (6) as I understand most people do not always want to purchase 100 of these at a time.
They are manufactured by National Union Radio Corporation and are marked JAN CNU 6SG7GT.
Each box is also marked as “Accepted December 1952”.
The tubes are in excellent condition with all pins shiny as the day they were made.
Prior to shipping I will remove them from a sealed carton that was sealed sixty plus years ago in 1952 by the manufacture and tested.
All tubes will be tested on my precision 660 tube tester and guaranteed to be void of any defects or they will be replaced at no charge.
All tubes will be securely packaged and guaranteed to arrive safe!
Please email me with any questions prior to bidding. Also please don't forget to check out my other auctions as I find the time to list other great items.
I have a lot more tube types and other great items to sell.
As always, thanks for looking at my items and good luck bidding.
