I have a pair of vintage Tung Sol 6L6GCs. They were NOS. I bought them about a year ago and used them for about 20 hours. I was deciding between Fender with 6L6GCs and a Marshall with EL34s. I picked the Marshall. I just sold the Fender, but kept the tubes. I dont have any use for them. I am asking $65, I paid a lot more. I may trade for pedals, pickups, EL34s or other guitar related items.
