there are more than 30 years, it was my first hifi amp;. I sold I know why, but it was stupid! I always regret! and a year ago, I found one on ebay, and I did not rachet for tro pcher. and a real treat !!!!! JBLL 50 is coupled to a pure pleasure to listen to everything that is pop rock and jazz, with also a platinethorens TD 145
, I recommend this amp to anyone looking for a good little amp, clean sound, well Dfine, with an impeccable quality of construction. if you find it real cheap, buy it, you regret it!
