Have an M-12 Mercury on the way and the previous owner is supplying a couple of adaptors for the 6SL7 tube sockets that enable the use of 12AX7 types. No experience with these 6SL7 tubes on my part. Is this safe or would there have to be changes made inside the amp to allow safe operation?
Honestly, there is no reason to change. finding NOS 6SL7s isn't too hard, or expensive. Alternately New sensor remakes them under the Tung Sol brand. and they are pretty good.
the adaptors might be nice to keep on hand just in case you need a tube in a pinch and don't have any spare 6SL7s but for the most part it they are not hard to find, and they can be ordered online and delivered in a matter of days.
