Well this was a surprise in several ways, I'd forgotten I had it in my "collection" and that it was so ridiculously good and that it was still working perfectly after 45 years. I remembered getting this amp and being pleasantly surprised at it not needing any fixing, I cleaned the noisy volume control and also cleaned the switches anyway and it played beautifully. I remember seeing these for sale in the mid 1970's at Butler's Hifi in lower Hutt, I couldn't afford one on my school cleaning and my Dairy employee wages, I was 14 years old but had I acquired one I think it would have lasted rather a long time before upgrade; I have been listening side by side with some later and rather more expensive, and big name, amplifiers, from the orient and it is significantly better. Clean detailed, a great sound stage, and despite having capacitor coupled output, plenty of tight clean and deep bass. It's warm and non fatiguing. According to Perreaux it was their first product and ran in class A, it does have quite a high bias setting but class A....? Well it does have large finned heat-sinks and gets quite warm, not hot but warm to the touch, it does not have a large power transformer but it's only meant to be 22 watts (per channel?) Anyway it's "pretty darn good" especially for its age. Interestingly it has better sound, and construction, than the Perreaux 1221. This won't be going anywhere soon, it's hooked up to a nice system for extended listening and appreciation. My example is also pretty close to mint condition.
