It's about time we get to some really GREAT tubes!

Here is a matched quad of RCA-branded, Mullard-manufactured mid-60's production Xf2 double halo EL34/6CA7's. These are NOS, but the printing has been smudged and the tube boxes are very poor. Electrically, though, they are all VERY closely matched and absolutely unused except to test them. While they are not TOTALLY unobtainable yet, they have become VERY rare and EXTREMELY expensive. Vacuum Tube Valley would want more than $400.00 a PAIR *IF* they actually had any in stock! (They don't!) Tube World has a "loosely-matched" pair in stock for only $375.00! If the printing and boxes were good, I would HAVE to price these at $600.00 MINIMUM!

But since the boxes are SO bad, and the printing is quite a bit less than perfect, you have a once in a lifetime opportunity to buy them for only $400.00 for the quad.
First come, first served!
Thanks for looking! I hope I can be of service to you
Sincerely,
Bill Thomas
