Pretty rugged, OK sonics.


I bought 5 of these back when they were $5.00 a pop, for the input of the linestage of my old QS full function preamp. For whatever reason, that preamp tends to be hard on the 12AU7 tube; even the manual states that if things start getting noisy, trying replacing that tube 1st.
In this application, the sonics are OK. Tends to hold up better than stock 12AU7's but I still will have to replace this tube before I do all the others, in this preamp. You need something rugged, not microphonic in a 12AU7, this is your tube.
