As some might remember, I have been thinking for over a year about moving beyond my LD 1+ to a 6AS7G-based OTL. Of particular importance to me was being able to use all my favorite tubes in my new amp. Today, I took delivery of a Glenn OTL. Of particular note, this amp can use either a pair of G3gs or any SN7 (6SN7, 12SN7 or 25SN7). I am not aware of any other 6AS7-based OTL that is designed from the ground up to use a pair of C3gs as drivers as well as SN7s.
Pictured, with a 3DG4 rectifier, Ken-Rad 1633 (25SN7) and two Chatham 6AS7s. And yes, it sounds much better than my LD 1+!
In fairness, we need to remember that our LDs were designed to use triode-strapped 6AK5s, not 6SN7s or any other double-triode, and certainly not a pair of C3gs. For sure, these tubes sound great in our LDs, much better than any 6AK5, but since the biasing is not optimal for these tubes, they cannot sound as good as they do in an amp that has been carefully and deliberately designed to use these tubes.
And now please excuse me as I return to the music.
