I've bought these tubes about 8 years ago NOS when I first got into tubes. I tube rolled several VT 231 and 6SN7 tubes and settled on the Ken Rad VT 231.
So these tubes have ben in 'the closet' for all this time. They only where used for less than 100 hours during my tube rolling time.
The boxes say that they have been matched.
T1 3000
T2 2900
on both tubes.
- JAN-CHS-6SN7GT J4
- tight bases
- no loose pieces
- clean pins (no oxidation)
I would like to sell these for $ 80.
