Pioneer SA-600


This handsomely styled unit from Pioneer is perfect for the serious stereo enthusiast who is building his system within a stipulated budget.

At a very practical price, the SA-600 provides a host of important features and a lot of professional performance that will do musical wonders for any home stereo system.

It's circuits use only long-life, low-noise silicon transistors, and thus the frequency response and signal-to-noise ratio are superb.

The unit is also very versatile, in keeping with the Pioneer audio philosophy of giving the most for the consumer's money.

You may use up to two tape decks or two speaker systems with the SA-600, and you may also adapt the unit for multi-amp use.

More for your money? The SA-600 is probably the finest value in a medium-power amplifier now available.

Pioneer SA-600

Excelente construccion, como el Sansui AU-6500, muy buen sonido, como el receiver Pioneer SX-600, esplendida implementación, como el Yamaha CA-400, con unos altavoces eficientes y para una habitación pequeña su potencia es satisfactoria, buen diseño, estremadamente simple y facil de reparar, hay algunas modificaciones sugeribles:

Aumentar el valor del capacitor principal a 4.700 uF X 63 Volts mas un poliester de 1 uF X 100 Volts, aumentar los capacitores de paso por 3.300 uF X 35 Volts mas 1uF de poliester.

En la sección de audio de potencia sugiero reducir R-41 y R-42 a solo 4.7 KOhms, para reducir la distorsión, también aumentar los capacitores de paso C3 y C4 a 22 uF X 25 volts; C7, C8, C11 y C12 a 220 uF X 35 de primera calidad; en la tarjeta del preamplificador sustituir los capacitores C19 y C20 de 47 uF a 220 uF X 10 Volts de primera; en la seccion Phono sustituir los capacitores de acople C9 y C10 de 33 uF por 100 uF X 6,3 Volts de primera.

Finalmente sustituir todos los capacitores de paso de señal por unos electroliticos de 4.7 uF X 25 Volts de primera.

re: SA-600

Since more than 40 years I daily enjoy my Pioneer Stereo Amplifier.
But, for some time past the speakers make a cracking noise when I turn the power on and softly turn the volume button. Often the sound even cuts.
This distortion stops by turning the power switch on/off or turning the volume button to increase the volume or by setting some times the selector switch on/off or the various switches up/down.
Probable this problem can be solved by injecting liquid scour inside the switches and the potentiometers.
My question: how can I remove the switches and the control buttons for this purpose?
Wondering if anyone has a suggestion. Thanks.

re: SA-600

Did the popping and cracking stop after using the liquid scour? I have a similar problem with my SA-600.
