I bought one of these at a house clearance traders market along with a load of other gear, took it all back to the workshop to test, fix and sell. I had tested enough amps through the speakers I was using to know when I had a good sounding amp. This one went straight on the top shelf.
I'm having that.
The sound is very 'crisp', clear and pleasing. The bass sounds like the control could maybe go a little bit more clockwise but with a descent set of speakers this amp sounds brilliant. Typical build quality of a '70s amp, metal cabinet and front panel, this one is in top condition and the two big VU meters look good. The tape in and out sockets on the front are useful for connecting up phones and ipods etc, it is surprisingly loud too.
I was a little bit disappointed to find two STK ICs in the output stage rather than a collection of transistors but when the lid is on you can't see them, the sound is good enough to ignore that anyway.
I like '70s amps and audio equipment, they're built to last, look and sound good. This one ticks all the boxes.

A wonderful little amplifier.
Firstly, it is beautifully made; from a time when such things mattered. Everything is metal, and perfectly machined, it is inherently an item of quality (as are its fellows in that JVC range) which makes it a joy to own and use. It is admirable internally also, with a chunky power supply and quality components throughout. It uses Darlington output packs, which have sometimes been frowned upon in 'hi-fi' circles, but I strongly suggest you forget about that and use your ears! In any case, the nature of Darlington output packs (output transistors integrated into a large chip) means that they do not need adjustment and thus are likely to be working now as well as when they were new.
I've had some expensive Naim stuff in the past, and more recently some big and impressive Sansui amps, but for me the sound of JVC amps is the most natural I have come across. I love their Dynamic Super-A amps from the 1980s too, but I think these late 1970s models are very special.
The word I would use to sum up the sound of this amp is beguiling. It is natural sounding and never harsh; it sounds musical and 'right'. Despite it being 'only' 40 wpc, these are '70s watts and quite sufficient to drive most speakers to serious levels without any sign of strain. The highs are extended and transparent, mids are beautifully fluid (a particular strength of this amp), and the bass is controlled and deep. If you like powerful bass you will enjoy this amp. There is also a sense of three dimensional depth to the sound, which produces an impression of reality and spatial positioning of the various instruments and/or voices. The sound is not as 'analytical' (or perhaps as initially impressive) as a big Sansui, for instance, but it is more enjoyable to listen to for long periods of time or at high levels. This is a highly musical amplifier, it makes me want to play more music...
There are a lot of these around because a) they were popular and well-reviewed at the time, and b) because they are so well made that they last. I think people have also held on to them because it might be difficult to find something modern that sounds anywhere near as good!
It also has Tape 2 sockets duplicated on the front, which is very handy for plugging in your iPod/whatever...
A fine amplifier....from the glory days of Japanese hi-fi.
