For Sale: Tested and working classic high end amp. Made in Japan between 1972 and 1976.
Works great, excellent sound quality, tons of high end features, no issues. No static or hum. All switches and dials working correctly. Shows very little wear. Power indicator light is good. Lots of inputs and outputs- 2 phono (turntable), 2 aux., 2 tape deck inputs/outputs. Has all the standard amp features plus adjustable turnover frequencies, hi filter, low filter, loudness, optional preamplifier outputs, and more.
Some info from the web:
Although the TA-1150 looks more gimmicky than its TA-1130 elder, thanks to its linear vertical volume slider, it is in fact a step further into full 1970's engineering - even 1980's if one considers the power transistors that were used.
DC-coupled, SEPP-OTL, balanced differential power supply, DC preamp section with complementary low-noise transistors in each EQ and tone amplifiers. And the eight power transistors themselves aren't the usual bulky TO-3 boxes but modern devices which could fit onto the heatsinks of a TA-N77ES or a Marantz SM-80 - in 1972 !
Feature-wise, the Sony TA-1150 was well endowed, even going as far as integrating 4-CH compatibility (by way of a dedicated loop), allowing the separation of the pre and power sections (by way of another dedicated loop) and keeping the "center" output that was on the original 1965 ES TA-2000 and which the TA-1130 didn't have... The rest is more common : plenty of sources, low & high filters, turnover frequencies for the bass/treble controls etc. All steel and aluminium - no plug-in cards but built like almost everything still was then : sound & solid.
Just as the earlier TA-1130 or the original TA-1120 (and variants), the TA-1150 sold amazingly well all over the planet, along its dedicated ST-5150 tuner. Variants of the TA-1150 are the TA-1140 (depending on market) and a later TA-5150D which added minor circuit revisions in 1974 - the worldwide TA-1150 probably is the equivalent of that TA-1150D. Gradually replacing this very successful series was the 1st V-Fet generation in 1974, then the TA-F6B / TA-F7B in 1976, then the "new world" TA-F80 in 1978.
Marketing-wise, the TA-1150 was part of Sony's first "all together" system : the well-known Listen 5. There was no Listen 3 because, at that higher price point, serious audiophiles don't buy all-in-one packs - however good!
