Melz 6N8S. NOS, only used 10 minutes to verify it works. (Sounded pretty great btw). I bought this from a vendor in Russia on the eBay. By the time it got here, I’d purchased the Treasure Globe and it’s currently the top dog. SOLD!
GE 5691 red base condition is used. Note this is actually a 6SL7GT equivalent. Nice tube with a lot of life left in it. $60 Includes Shipping and PayPal
