The GEC KT88

In this video I have documented all the versions and iterations of the GEC KT88 tubes. Please let me know if you have any questions.

I have a pair date code 8611Z and they match your last tube. I have only the those and a pair of KT-66 one labeled Emitron BVA code MJ 10, and one Genelex code LF 10. I obtained the 2 pairs to use in my little Had Inspire SEP. Both pairs have a beautiful sound that is not matched by any of the 15 plus pairs of tubes I have for this amp. Regards, Mike B.

I've four quads of GEC KT66s, so I guess I'm a GEC fan too. Have you had the chance to compare the GEC KT88s to the KT66s?
