RCA 5963 12AU7 ECC82 Foil Getter Tubes, Matched Quad, Tested, NOS, NIB

Hello – I have a rare matched quad of RCA 5963 12AU7 ECC82 Foil Getter Black Plate tubes for sale.

These tubes are NOS and new in the box.

Although these are marked Arcturus, they were made by RCA. Arcturus was a tube reseller.

These have 17 mm long black ladder plates and foil getters. They were made between 1957 and 1959.

TV-7/B test results: ≥105 per section.  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.
