Description

The Pioneer SA-9800 has the impressive feature which is the NSA (non switching amplifier), created specially by Pioneer.

This is a type of amplifier that adopts the merits of both class A and class B amplifiers, and it excels in keeping down the heat loss and allows the transistors to operate all the time in the active region.

For this reason, a high output power with a very low distortion factor is yielded all the way up to the high frequencies.

Hi,

I am classic Audio Gear collector. I bought Pioneer SA9800 in faulty condition found one channel completely gone bad on power amp side. I hope to fix it with the help of Service manual on hifi engine. Don't know if required spares/components will be available!

Thank you,
Sachin

Does anyone know where I can get the volume control for the sa 9800 amp, part number acw 119? Alternatively of a supplier that will do a replacement dual ganged pot? I believe that there is an extra 'tap' for the loudness circuit????
