no longer for sale

Hello – I have a matched quad of GE 12AU7WA 12AU7 6189 ECC82 5814A mil-spec tubes for sale.

These tubes were made for the military are NOS and new in the box.

These have triple  mica construction, gray plates and halo getters. All four tubes have matching 1963 date codes.

TV-7/B test results: 110/110, 110/110, 110/110 and 110/110. Minimum is 56.

They have also been checked for noise and microphonics in the phono stage of my DIY pre-amp and are dead quiet.

All tubes are tested on my Dan Nelson calibrated TV-7/B or on my calibrated Hickok 539C. All of these tubes have been tested for transconductance, shorts, gas, leakage and life. All tubes meet or exceed manufacturer published specifications of transconductance (Gm) for the specified tube type. All tests are tested twice – prior to the listing and prior to shipping.
