Realistic SA-1000 integrated amplifier

The realistic SA-1000 was introduced in 1975. It's a 20 Watts RMS per channel integrated amplifier. The SA-1000A followed in 1977 til 1978 with the exact same shape but was then rated as a 25 watts RMS per channel. We've bought a 1000A back in 1978. This have been my main amplifier for over a decade. I still have it in hand but it's unused for about 15 years. It never failed.
