I have a hard time imagining $500 for a kt88, but then I never got the Beanie Baby thing either.
Could you imagine?
I was over at ebay and see that a quad GEC Gold Lion kt88 fetches over $500 there. Can you imagine finding in some old TV Radio shop old cases of them? Say a cellar with 10,000 tubes. We are talking a Million three. As wild as that may be, there is probably somewhere in this world a cellar full of Gold Lions.......gathering dust....
