From my Archive, Pioneer Flyer from 1979/80
Your SA-3000 is from a System, called Mini-System. It includes:
Amplifier SA-3000
Tuner TX-3000
Turntable PL-3000
Cassette Deck CT-3000
Audio Rack B-3000
Something so right in size and sound
The following pages are going to take you through a whole new world of stereo hi-fi components. The new world of the Mini Hi-fi System. You'll find the same fine performance that Pioneer's regular-size components are noted for but you won't find the large cabinetry and big dimensions. You'll find instead a hi-fi system that's been reduced in size but human-engineered for the human hand. You'll also see a uniformity in style that is a joy to find in systems of any size. You won't be able to hear it, but you'll be able to get an indication of the quality of the sound by scrutinizing the specifications. After you've given our system a test listen, we assure you that your ears will confirm what your eyes have already read. The Mini Hi-fi System. Something so right in size and sound-sold only by Pioneer.
The Pioneer SA-3000 Stereo Integrated Amplifier. The big little power source.
For an amp of this size to produce 40 watts of power per channel, you know that some truly advanced technology had to be applied. You're right. Though the size has been greatly reduced we've been able to achieve a very low distortion figure of only 0.02 %. The circuitry itself has been newly developed for the push-pull drive in the Class "A" driver stage of the power amp to greatly reduce distortion in the high frequencies and to improve overall transient characteristics.
Three Independent Power Source Circuits. Sound quality reaches new heights. The internal layout of the chassis has been incredibly simplified and hence is all the more faithful to amp fundamentals. Left and right sections are completely separated for improved quality. Three independent power circuits; 2 toroidal transformers as well as special circuitry for low-level signals greatly improve performance, reduce distortion, eliminate crosstalk while achieving a high level of separation.
Substantially Wide Dynamic Range and High Phono S/N Ratio. To keep up with today's recording techniques. A phono S/N ratio of 86dB has been realized by using 3-stage DC circuitry with our new low-noise transistors in the first stage of the equalizer amp. Which all means that the SA-3000 is a good enough amplifier to handle and reproduce even the latest directdisc recordings with wide dynamic ranges.

It is from the Mini 3000 component system, from 1979 to 1980.

You mean the amplifier or the switches are a bad design?

The switches
The switches are poorly designed, made to break if u understand, but the electronics are good it sounds really well.
Any idea of where i can find these replacement switches? im in peru but a friend of mine can buy them in the US and send them here.

Anything can break with enough force. Don't see how that could happen with normal use. Never broken off any of mine and I've had my SA-3000 for 30 years!
If you have a source for those switches I would go for it. Finding another SA-3000 to salvage switches from would probably be highly unlikely especially in Peru.

I suppose
I didnt broke them, i bought it like that, i didnt know what hapened or how they broke, but they look very fragile, i will try to find them in PARURO, that is a place when all the electronics are selled in Lima.
Either i will have to replace it with another similar switches.

Tech question: How does an amp put out 40 watts p/c at 8 ohms and also 40 watts p/c at 4 ohms? I would think the 4 ohm rating would higher, if not double.
"POWER AMPLIFIER SECTION

Where did those specifications come from? I looked at my service manual and it has 8 Ohm specs only, no mention of 4 Ohms. Also notice you cannot run Speakers A and B simultaneously. So seems to me this little amp is not really intended to be used with a 4 Ohm load.
