One matched pair of WHITE LABEL Amperex 7308/E188CC USN-CEP vacuum tubes with gold pins. These are Made in USA in 1964.

These highly sought-after (with a good reason) White Label 7308's are made for US Navy, and they are exactly the same tubes as Amperex White Label PQ 7308 tubes. (only with tighter and more stringent military spec)

They have "VR" code which indicates 7308 type tubes.
Tubes are made in 1964 and with etched Date Codes: VR5*4A & VR5*4D (January & April of 1964).

My most favorite 7308 tubes, Quiet, Vibrant, Dynamic and Warm.
Many consider Amperex 7308 tubes the best of the best in 6DJ8 family tubes.
Rated to have 10,000 hours useful life!

Tightly matched.
Very low noise (phono grade) - tested in actual preamp.

I have more of these wonderful sounding tubes, so please ask if you need more than one pair.

Paypal add 3.5%.

I guarantee excellent performance, so buy with confidence.
If you are not satisfied with my tubes for any reason, I will issue full refund for your purchase price.

All tubes are installed into an actual audio circuit to screen them for internal tube noise/micorphonics.
