Hello – I have a matched quad of RCA 12AU7A ECC82 6680 Clear Top tubes for sale.

There are two quads available. This listing is for one quad.

These have 17 mm long gray ladder plates and a side getter.

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: ≥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.

Please e-mail me if you have any questions.

Please check out my other ad’s on Audiogon.
