Best nos 6sn7g for my Atmasphere mp1.

I believe the previous poster failed to notice that you're requesting MP-1 recs. I have an MP-1 paired with M60s and have found the Sylvanias to be my preference in the MP-1. Do yourself a favor and get in touch with Andy @ Vintage Tube Services and do it soon as he's closing up shop pretty soon. Discuss your sonic priorities and he'll take it from there. It may take a few weeks but you'll get the real deal NOS stuff graded expertly by a pro. Nuff said.

Hey guys, it's me again. Since this topic has resurfaced I thought I would sheepishly pop in and apologize for apparent rumor mongering concerning Andy at VTS. However, in defense of self, I must disclose that the info I passed on here came straight from the horse's mouth. I had called Andy to place an order and he confided to me that he was going to commit to a "new venture" and would probably be closing up within six months. Well, four years later and he's still selling tubes (so far as I know) so I guess the "new venture" was stillborn. Hopefully, no harm done.
