It's time again to pare down my tube collection. This time I have some nice 12AU7 tubes and variants. As usual, prices include shipping and paypal fees.
All tubes tested on my calibrated Sencore 162 tester, for emissions, shorts and grid leakage. All tubes also sound tested for noise and microphonics.
Amperex 12AU7 pair. Tested at 92/91 and 92/93. Typical reading for new 12AU7 tube is approx. 90-92. Very nice pair. $27 pair.
