I tested a number of power amps and I really liked the ability to run both EL-34's and 6L6's to blend the sound. As far as it being better, Mesa tried to fix that by releasing a newer model (2:90?) which is only 2 rack spaces and close to 1/2 of the weight. I like my beast though. It's solid and puts out some serious sound.
Where Obtained: Ebay
Stereo all tube power amp
4 EL-34 tubes
4 6L6 tubes
4 12ax7 tubes
95 watts per side in Simul-Class mode (runs both varieties of power tubes)
Switchable down to 30 watts per side (uses only the EL-34's)
2 volume controls - my model has them on the back.
Power and standby rocker switches on the front.
Aforementioned 95/30 watt power switch
2 8ohm speaker outs per side
2 4ohm speaker outs per side
Excellent sound quality. As this is a power amp, a separate preamp is to be used, and that is really what's going to shape your sound. I run it with a Soho 4 channel preamp (think Kitty Hawk Quattro) and it simply screams. It works perfectly for what I play, whether it is metal or praise and worship.
Not very difficult to use. Signal goes in, turn your knobs to whatever volume you want, flick the switch to which wattage/style you want, run a speaker line out from your selection of 8 outputs. Not much to it!
Mine is what...10 years old at least. Takes a licking and keeps on ticking, but then again, it's a Mesa and built like a tank. Speaking of which, it is a tank. Takes up 4 rack spaces and tips the scales at about 50 pounds.
