Hello – I have a matched quad of RCA 12AU7A ECC82 Clear Top tubes for sale.
These have 17 mm long gray ladder plates and a side getter. All four tubes were made in the early 1960’s.
These tubes are said to have excellent sound and it is also said by some that the side getter contributes to the low microphonics of this tube. These are also said to be among the finest sounding 12AU7's.
TV-7/B test results: 100/90, 85/90, 85/95 and 85/95. 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.
