You are looking at a piece of electronics older than the internet. You will likely run into issues. However, the SA-8900 II is a tech's dream because it is built with discrete components (no proprietary chips that are impossible to find today).
As with any vintage amplifier, maintenance and repair are essential to ensuring the long-term reliability and performance of the Pioneer SA-8900 II. Owners should be aware that the amplifier's capacitors, resistors, and other components may need to be replaced over time, and that periodic cleaning and adjustment of the unit's controls and switches may be necessary. pioneer sa 8900 ii

If these components fail, repairing the unit requires "surgery" to graft in different modern devices. You are looking at a piece of electronics
