I have a matched quad for sale.

According to thetubestore...."These are the hard to find NOS (new old stock) of premium quality in both sound and construction."

They are from Cryoset, when Cryo had them. Now, they only have the Reflector 6N23P-EV's.

Maybe, 10hrs tops....on them.

(Why only 10 hours? I made sure they worked and were similar to the stock tube quad sent with my ZMA....then I shelved them and got into NOS other tubes..... . I should keep them and compare........but, I'm willing to let them go.....). Heavily into the expensive stuff. I keep the original quad from Steve....to know/periodically put in.....the intent signature.

I only use Telefunken, Mullard, Ediswan & a couple pair of Tungsram's ~ exclusively. (I currently have my Tungsram 6922 NOS Platinum's in. Dynamic! .....sweet and smooth........) .

I won't get into debating whether they are the same as the EV's, that Cryoset now sells. Mine are as pictured/premium, in the tube store link I provided. I trust, that the tube store owner knows what he is talking about..... .

These are great NOS tubes. I however, prefer rotating the ones I listed. These should not collect dust for the next 5 or 10 years.

NOTE: in thetubestore thread to click he lists 23n & the picture he provides shows 23n....mine are as well: 6H23n-EB. However, in print, he put p-EB. He does state the p & the n.....just wanted to make clear if you don't read the whole written copy.

Anyway, not open for debate. These are the premiums according to thetubestore.

I wanted to list here......before putting in AudiogoN's tube section.

SERIOUS INQUIRIES ONLY.....PM me your number......and I will send text picture.
