G.E. ,RCA and Sylvania made very nice versions of this tube! The plate voltage rating is just a little lower than for a 12AU7, but for most applications, it will work fine. It has a rugged cathode and should be long lived, similar to the 5814. Watch this tube, as it is plentiful now and prices are low. As audiophiles discover it, the rush will be on!
