I have had this amp since 1975. It is probably the best thing I have ever bought as it is still going strong. Switches and volume control are a bit noisy now but I have used it at a disco in the power amp mode and I never run out of power even in a big room. Reason not 10 out of 10 is because of the volume control. Better with a round knob than a slider.

I have a Marantz 1060, my recapped Sansui AU 6500 easily took its place. This Sony is superior to the Sansui. Can't wait to hear it with new caps.

I had one of these back in the mid-`70's and it was just a monster amp, but I foolishly sold it for moolah when times were hard.

In a line of Sony amplifiers nicknamed The Mac Killers because it was said that in a side by side comparison, to sound as good if not better than the McIntosh amplifiers of the day. That is enough said right there, but my experience with this 1973 30 watt amp is that it sounds better than may vintage 40 watt Marantz amp on my 1979 New Advent Loudspeakers in the real walnut cabinets. Here we have clear defined highs, where synths, strings and voices are not overly crisp or crackly. Lows are deep, full and warm with no audible distortion. Even digital recordings with their poor quality, muddy lows and crispy or harsh highs that are hard on the ears sound good on this system. For more info the HiFi Engine Library has a very good description of this amplifier and these loudspeakers.

@ My3kidsfather-You say the tech could not fix this amp, I guess he was not much of a tech. This unit is actually a brilliant design with beautifully realistic natural sound. I recently picked one up it sounds as and maybe even better than my Marantz receiver. Why did you not do the simple fix and exchange it for another one since you bought it new?

re: TA-1150

I bought this amp new (it was new too in the seventies) when I was just 16 yrs old- my first stereo. Frankly it was aweful. It had a bit of noise at all ranges especially with my better headphones. I sent it out for repair and the tech said he could hear the noise too. No repair possible. It just a bad design from the get go. Of all the TA amps from Sony I picked the lemon.

I was reading a few days ago (some forty years later) about another Sony int. amp for sale and in the guys comments he mentioned it is known that another amp, the TA-1150 is to be avoided as it was a poor design with expensive parts. I have not been able to buy a Sony since but now I know it's not me but Sony's bad. Problem solved.

You guys needed to know.
Bill Missen.

P.S. the TA-1130 and every other TA amp is good- just avoid this one.

Why did you not just exchange it for another one since you bought it new. Mine at 41 years old sounds great, natural and clean.

re: TA-1150

Thanks for the info. and manual pdf. Last Saturday I picked one of these amplifiers up in the wood case at my local Goodwill in minty condition for $3.50, SCORE! I have read that it was nicknamed "The Mac Killer" because it was as good and possibly better than the McIntosh amplifiers sold at the time. It sounds great with my walnut Advent New Loudspeakers, also a Goodwill find for $11.00 that just needed re-foaming which only cost me $29.00 for the kit on ebay, and my Pioneer TX 6800 Tuner or Bang & Olufsen Beogram RX Turntable. I am using a Kenwood GE 7030 equalizer that I bought new back in the 90s, but it sounds so good without it, you really don't need a equalizer. This is "audio heaven" at an unbelievable price.

les deux manuels parfaitement lisibles

Merci mille fois pour ces deux manuels, le TA-1150 est une très belle bête, à laquelle on ne comprend pas grand chose sans ces magnifiques schémas ! Continuez à nous collecter des schémas vintage, ☺ car ces beaux appareils le méritent. Cela évite qu'ils finissent à la poubelle ! Vous êtes MA source numéro UN, et de loin !

Many thanks for the manual. The amp works creates a warm detailed sound with classical and jazz music and, now I have the manual, seems like new. Who's a lucky boy then?
All the best
