I have 2 strange brand 6SN7GT which is said CBS/Hytron. The printed brand is Premier, date code 5-56. If this date code is correct then this should be bought from other brand and resold under CBS/Hytron cause at this time, CBS/Hytron stopped manufacturing tubes themselves. I cannot find out which is the tube original brand cause the top round mica with spikes and the bottom round mica look quite strange.

An externally hosted image should be here but it was not working when we last tested it.


Please help to give your comment.

Thanks
