6C6 Sylvania true NOS/NIB, milspec tubes, immaculate condition, premium pair

Description

We found 3 more pairs in a box, so here we go again…

One excellent pair (2 pieces) Sylvania 6C6, special military quality tubes. Early version from the 1940ies with light blue Sylvania print, US Navy provenence.

All three pairs have very close values, call them matched if you like (less than 5% difference)

All tubes are tested and are guaranteed to have 100%+ emission. 

These came in a military bulk crate, hence no orignal box.
