Engineering excellence doesn't seem to be his bag...............
Obviously not. It sounds like he has experience with one of those tube
"preamps" designed to give that "tube sound". You know, the ones that
run a 12AX7 with 24V (or less) on the plate.....

The worst tube circuit I work with is a DBX 386, 200V plate, and I switch
between Philips ECC83's and Telefunken ECC85's, which come in handy for
brightening certain instruments without the damaging effects of a half-assed
EQ plug-in on treble.

Just because I incorporate concepts and terminology from other areas of
audio doesn't mean I don't have a working knowledge of what's pertinent
here.
