GE 6L6 GC's....what do I have here?

[evco]

A co-worker brought an old Heathkit power supply in which had the below GE 6L6 GC's in it. Have not tried in an amp yet (will be trying later this week) & not sure how much use they've seen but am curious if they are any of the coveted GE's of yore.

Anyone know what these are, run-of-the-mill GE's... something special?

Thanks for any info you can provide,

Eric

Yes, definitely coveted as are ALL US and West Euro made audio tubes.

Love 'em - kinda sound in between RCA blackpates and Philips STR 6L6GCs.
