I have several (at least 10) Amperex USA White Print Navy USN-CEP 6922 E88CC Gold Pin tubes for sale. Internally the same tubes as Amperex White Label PQ 6922 tubes, but it is my understanding these were made for the US Navy with tighter and more stringent military specs. I have the OEM box's for most if not all of these. Labels are mostly legible on most, some worse than others.

All test with NOS readings on my MaxiPreamp II digital tube tester. Not tested for microphonics but if you contact me within five days, I will take care of any issues. These tubes sound awesome in my Torii.

$150 for matched pair's

$275 per two matched pairs (quad - four tubes)

The big tube dealers used to sell these for $200 a pair. Now they are selling for $325.
