JVC 4VN-550


The 4VN-550 is a high value stereo component. Packed with the latest of JVC's developments it's a 4-channel amplifier which leads the way in sound. S.F.C.S (JVC's simulated four-channel system), advanced BTL connections, a frequency response from 20 to 40,000Hz; the list goes on for a very long time.

Build up a stereo system around the 4VN-550 and you'll never regret it. You'll have an amplifier which will last for a long time without becoming dated, as the centrepiece of a 4-channel or 2-channel system.

I found it in a charity market i loved immediately his vintage look, all these little knobs waiting to be turned and the minimal green lights, the stunning use of all that heavy metal on the faceplate and all around... it had the need of some capacitors replace, after done i was surprised for his nice sound warm and singing more power than expected by a 25w xch, in these days it can't be called high end but his lovely pleasant sound let me use it with pleasure anytime, it's my second amplifier after the couple Sanyo Plus p55-c55.
If you found one, take it, you'll love it.

I have had my 550 since 1973!! It has not missed a beat in 44 years and is a superb little amplifier. I originally had it as my first foray into HiFi and part of a quadraphonic system but use it today as part of an adjunct stereo setup. Despite also currently using and having previously owned several top level American systems (Citation, Phase Linear and currently Audio Research), this little JVC amp keeps on performing well and just keeps on keeping on. Would recommend it to anyone interested in vintage amplifiers as it was certainly built to last.
