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."
http://www.thetubestore.com/Tubes/6922-E88CC-Tube-Types/6H23n-EB-6922They 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..... .
$239.80 for a Quad from thetubestore...........
Selling for: $190.00, which includes shipping/Lower 48 states only.
USPS ~ with tracking number provided in PM here & PayPal.
I will cover the PayPal fee.
PM me your PayPal email address and I will request payment.
I will promptly ship.
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.
