Description
This is a GE 6GH8A Vintage GREY PLATE PREAMP VACUUM DYNACO SUB TUBE Tested NEW NOS these came from a couple of tube caddy's that are full of NOS tubes. The tubes were tested as shown in pictures. These were tested with my newly calibrated Sencore TC-162 tube tester and both tubes sections seem to be in the good 100 % + range with no shorts or grid leaks, life test good. These would be nice for a new project or replacement tubes in another. Please look at the pictures for condition. I am selling all my amplifier tubes and parts. SYL -11
