WHAT IS "SIMUL-CLASS"? Simul-Class power is like having two different kinds of power
operating simul-taneously on each channel of the amplifier. One power section is wired in
"Class A Triode" and uses two EL-34 tubes. "Class A” power is the oldest and purest form of
amplification; it’s warm and "vocal" tone is the heart of the Simul-Class circuit. The other
power section uses two 6L6 tubes, wired in the more modern and efficient "Class AB"
configuration; this section provides the bulk of the "muscle" in the amplifier. And by
combining these two "classes" of power design, the Simul-Class circuit reaps the rewards of
both. The 30 watts of vintage Class A tone combines with 65 watts of efficient Class AB
power to produce a total of 95 watts per channel of the warmest, most musical power you've
ever heard! Or you can use the "Class A/Simul-Class" switch to turn off the Class AB (6L6)
sections, and run the Class A (EL-34) sections by themselves. This allows you to drive the
amp harder for greater power amp distortion, but at volume levels you can more easily
control.
Now that we've briefed you on the 295 "philosophy", here are some specifics on its
operation.
These two rocker switches on the 295's rear deck (again, one per channel) allow selection
of either the "Class A” Mode or the "Simul-Class" Mode. In Class A, the outer or end pairs of
power tubes (EL-34's) operate by themselves, while the inner or middle pairs (6L6's) remain
in "standby". The EL-34's are wired in a "Class A Triode" circuit for optimal warmth of tone,
and at lower output levels (about 30 watts per channel). The Class A mode is ideal for
recording, rehearsing, or any situation where you need great tone at low volumes. In the
"Simul-Class" Mode, all eight power tubes are operative (with the 6L6's adding about 65
watts of "Class AB" type power per channel) to produce a total of 95 watts per channel. It's
this combination of "Class A" warmth and "Class AB" efficiency that makes the Simul-Class
295 ideally suited as an instrument for guitar amplification.
