Mesa Boogie 295 Simul-Class Power Amp.

Stereo/Mono

TUBES:

4xEL34

4x6L6

4xECC83

CLASS A 2x35w (4xEL34)

CLASS AB 2x95w (4xEL34 +4x6L6)

I will send this amp in a rack case. It's a 4U plywood and it will package in cardboard too.

I'll add the photos when I've assembled this amp into it.

Fully working order!

I'm open to offers too...

OUTPUT CONNECTIONS.

Each channel of the 295 offers two 8-ohm and two 4-ohm outputs (all 1/4” jacks) for connecting speaker cabinets. Unlike transistor amps, the 295 will deliver full power at either 4 or 8 ohms, and mismatching of speaker impedance will not cause damage or severe loss of power (extreme mismatches will decrease tube life, however). Avoid running either channel without a proper load - or damage may result! When using more than one speaker cabinet on a single channels remember that the total impedance goes down as more cabinets are connected. For example, if you use one 8-ohm cabinet, use one of the 8-ohm jacks. If you use two 8-ohm cabinets on the same channel, they will be operating in parallel and the total load will then be 4 ohms. In that case, each cabinet should be plugged into a 4ohm jack.

CLASS A / SIMUL-CLASS SWITCHES.

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.

BIAS.

As with all MESA/Boogie amplifiers, the bias is permanently set during construction and never needs adjustment. This saves you any technician's fee for readjustment when replacing tubes, and prevents the bias from "wandering" or being accidentally set improperly.
