The ACT-021 Pioneer Balance Control Potentiometer SX-3700 is a high-quality audio component designed for professional use in various audio systems, particularly in vintage Pioneer equipment. This potentiometer is a crucial part of the balance control circuit, allowing users to adjust the left and right channel levels for a perfectly balanced audio output.
The SX-3700 is a 10-turn, logarithmic taper potentiometer, which means it provides a smooth and precise adjustment range. The logarithmic taper ensures that small adjustments near the center of the potentiometer's rotation correspond to smaller changes in audio level, while larger adjustments towards the ends of the rotation produce larger changes. This makes it ideal for balancing audio signals, as it mimics the way our ears perceive changes in volume.
The potentiometer is made of high-quality materials, including a durable carbon composite shaft and a heavy-duty plastic body. The shaft is designed to provide smooth and accurate rotation, even after repeated use. The body is designed to be resistant to vibrations and impacts, ensuring reliable operation in a variety of environments.
The SX-3700 is a 6.3mm (1/4-inch) diameter potentiometer, which makes it easy to integrate into most audio systems. It also features a gold-plated contact for improved signal conductivity and longevity. The potentiometer is available in a variety of resistances, from 10k to 1M , allowing users to choose the one that best fits their specific audio system requirements.
In summary, the ACT-021 Pioneer Balance Control Potentiometer SX-3700 is a high-quality, durable, and precise audio component that is essential for achieving perfectly balanced audio output in vintage Pioneer equipment. Its logarithmic taper, durable materials, and gold-plated contact make it a reliable and long-lasting choice for audio professionals and enthusiasts.

Please see my pictures for details. I have a number of other Pioneer sx parts, collectibles, magic cards, and vintage electronics listed feel free to take look.
This may need a shot of exit, but is guaranteed to work for you. This is in good condition but the shaft pinched together at end and I think it bent slightly as well. This may work on other Pioneer receivers and possibly receiver brands as well.
