So sorry, had to react to the other previous review: too negative. This machine was built for house. Bought it new somewhere in 92 and still use it on almost a daily basis. Just love the full sound it blasts out, the machine is a bit heavy on the bass side, but that's where the bass and treble are for. Use them. The CD player I bought with it also still does it work perfectly. Never cleaned it, just use it over and over. Never skips. Amplifier has been serviced once, couldn't live with a cracking sound in the volume control knob. Was just a bit of dust, no podmeter failure or whatever. Just dust. The machine is 25 years old, but still functions 100%. In combination with two small Chario Syntar speakers: a dream for playing electronic music. It's appearance? Love the design. Black and black and black. No fancy lighting what you don't need, just one red on/off button light. They still pop up for cheap on Ebay. Get it. Oldskool machine. Fat sound.
Mmm... Technics amps from the 90s... Why is there always something not quite right with them...? For a start - they weigh a bloody ton (feels like some chump at the factory slipped a brick into the unit for a joke)... and they also have these sharp edges and corners (thank you, sadomasochistic designer!)... the knobs are kind of tight and little and weird to turn, making you feel output-wise like you are doing nothing, but physically twisting hard on the way-too-tight dial... and the in-out buttons are kind of... clicky-springy and immediate and weird... and all those "Class A" and "Class AA" series were made in a sort of miserable-looking grey-green black colour... OK, OK, for all of you out there not as colour-tactile-sensitive as me... This is an OK amp, albeit a bit scary - the red light on the front reminds me of Maximilian's eye from the Disney sci-fi movie - "The Black Hole" - staring right at ya...
Inherited from a colleague in 2013 who had used it near-enough every day since he bought it new, the only things that didn't work were the Tape Monitor button - you had to hold it in, otherwise the whole sound would just cut out (any solutions out there to fix this, web-guys?) and the left speaker output - it was flaky, as if there were a loose connection somewhere (solutions are very much welcomed, hyperspace heads ;-)).
Nevertheless, again, as with all 90s Technics amps, it worked good enough (with a constant finger holding in the tape monitor button); it did however sound a little on the "flat" side - the bass and treble functions didn't really make the sound as rich in fidelity as, say, a Kenwood KA 3020SE, but hey, that's another kettle of fish. Adjusting the bass and treble is truly needed here, but the sound just doesn't seem to "jump out at ya" - it was as if you were watching "Avatar" in 2D. (God forbid if you pair this behemoth up with the Technics RS-B355 cassette deck [reviewed elsewhere on this site]... you'd have a sound flatter than a Dutch pancake that's been Steam-Rollered!).
But hey - if you inherit this brute, like I did, or find this monster for a few green folding ones, or in yer Auntie's attic - it would be a good "spare" if your slightly better amp finally gives up the ghost one day. A great substitute or temporary replacement.
Overall, it warrants a 3-score, but it's a very high 3 ;-)
