This is a direct copy of the original Genelex KT-77 from the 1970s. It swaps with EL34 for a rich beautiful sound. Bias them around 30ma just like EL34. These are a matched octet that I bought from Eurotubes last year. You can read about them on Asylum. These have the correct 0.093" pin width. They were very gently used in my Manley Snappers on two short occasions with easy 8ohm speakers. They have about 15 total hours on them, so they are not even broken in yet. Original receipt, Eurotubes sticker (woopee!) perfect like new, but with a nice discount. New price is $72/quad from eurotubes.com, $80/quad from thetubestore.com. I'll take $55/quad or $100 for the octet, plus paypal and shipping.
Thanks for reading!
