from harmony central:
An all tube, class A 1X12 (or 4x10) combo. This amp uses a pair of 6V6s' and/or 4 EL84s' for power. A knob ( named Progressive Linkage ) on the front panel allows you to select power tube types or combine them. The pair 6V6s' are rated 15 watts, with the quartet of EL84s' it's 33 watts, or combine them for 38 watts. Very very cool indeed. The preamp is all 12AX7s with both a solid state and tube ( GZ34 ) rectifier, hence the name Dual Rectifier. Controls are Volume,Treb, Mid, Bass, and Reverb. As well as the "Progressive Linkage". Two inputs, number 2 seems padded down a few dbs. There is also a Bright/Fat toggle. In the back there a variety of speaker outs for different ohm matching. An effects loop, Slave out, and Fuse round out the rear panel. No channel switching, graphic EQ, or master volume.
