Amazing amp.. owned it for 20+ years and can attest that this thing is an absolute tank, a bomb shelter.. back when I first got it I mainly used it as a subwoofer amplifier on a 2ohm load and beat on it for hours on end and it never skipped a beat! I'm a lot nicer to it these days and use it for full range.. the depth, clarity, warmth, stunning detail, and high current power is hard to beat with this dual mono block beast.

Bought this new in 1986 and it has been used nearly everyday since then. The only problem is the power on lamp has burned out; everything else still functions as new. I had a 7.1 surround system in my previous house, but have returned to stereo as I like the audio while listening to music better with two floor speakers vice the surround mode. This amp has traveled with me across the US. My only regret is I gave the Pioneer tuner that accompanied it to a friend sometime ago; wish I had that back. This is a rock solid 120w amp that I use with a Oppo UDP-203 disc player as it's source for audio input and I couldn't ask for more!

Outstanding soundstage, clarity, imagery of the music. Makes my cds sound like the best analog version of themselves. Paired with a set of Pioneer ST-500 Elite Speakers, Elite PD-17 101 Disc CD player, They make a remarkable trio .

Thanks a lot HiFi Engine for the availability of thousands of service manuals for free.


I had mine since 1986 still sounds great.
