I have a number of 813s, some GM70 graphites and GM70 copper, even have some iron for them. I am looking for some nice NOS 211s, as I recently ordered some nice 211 amps.
We can make a deal.
Mind you, I am not interested in Chinese, my amps come with G.E....would be interested in another pair of GEs and especially interested in other types of American 211s.
