--atmaspfere....With OT quality of sound of amp depends to OT, construction, kind of wire, kind of iron, wiring....But propertys, peculiariy of sound of every tube penetrates cross OT and SE /I feel/ sounds more warm and I can listen more hours. But OTL is better in some situations, sounds without breaks between tubes and speakers /without cap in output - OCL/, the sound is very deep, clear, bass in my OTL starts from 5 Hz!! But must have fast fuse if both sholders are disbalansed /if some sholders is out of mode....speakers are connected to common resistor with output currents in oposite directions for resulted 0 A/. But OTL has phase invertor like PP and signal goes between sholders and sound is close to PP.But I like my SE 2A3 RCA and my OTL 6AS7GE....
Charles....I accept Your words and Im allmost agree....Different tubes in SE sound different cool, I prefer my 1 W SE EL11 Telefunken in triod, that sounds better 300B....Every time I compair 2A3 RCA and EL11 Telefunken.
