30L15 / PCC805 - What can I use them for?

Seems the same as PCC/ECC85. It's been used in several designs, notably EAR, but it is actually not very linear, almost like a variable mu triode. This means it could find use as a LTP (phase splitter...), cathode folower. A usably linear operating point may be found for small signal amplification, o it could be used in circuits where some complementary distortion cancelation scheme is at work. In other words, probably not your first choice for use in audio. I actually have over a hunderd brand new Telefunken PCC85s waiting to find some use...
