Any tube heads here?

Speaking of tubes, does anyone have a line on where I can get a matched quad of 12B4s or 12B4As. This is/was a relatively inexpensive tube but finding a matched quad is like looking for hens teeth.

I sent you a lead via PM

thanks @rrwwss52 I sent a couple of sellers a note requesting a matched quad, anxious to see what they come back with.

What are you using them for?
