12AU7's for sale - Telefunken Pairs. Ribbed and Smooth

ALL212

Over the years I've collected a pile of 12AU7's and derivatives. I now have only 2 systems that need them and one of them uses the 12AU7 as a shunt regulator (Bottlehead Eros V1). The other is the Bottlehead C2A headphone amp. So... I have about 11 pairs of 12AU7's to be rid of.
