I'm more than happy using Ken Rad 12AX7's in my Decware ZP3 phono stage,  so I've decided to sell this geat sounding, very low noise pair of Mullard CV4004/12AX7's for $95, which includes Priority Mail shipping to the lower 48 states.

I purchased the two tubes from Upscale Audio years ago.  It's a "platinum" pair which they rated A for noise and A for microphonics.  
Test measurements are 17,000 and 17,500 for tube one.  And...17,5000 and 17,000 for tube two.  

With under 20 hours of use, I probably should not call them NOS, but they are very close.  These military tubes were made in 1981 and come in generic boxes, as they were issued in cartons of 100.

My price of $95 for the pair does include Priority Mail with Delivery Confirmation.  Paypal preferred, but I'll take personal checks or MO's.  Upscale lists these for approximately $100 (for a single tube) now, and t... depot asks $170 ea. for standard test single tube.

This is a superb pair for phono stages or preamps.

Thanks!

These tubes have been sold.

Thanks!
