I some comp style boxes and maybe a few other styles, I have seen a fixed capacitor that runs from relay. (these post left to right have a solder bridge across so that if amp is not in use it can simply feed thru/bypass the amp when relay is not active). This cap. goes from solder bridge to ground. What is the purpose of this cap and wouldn't it bleed off some of the drive going thru this section? Just wondered what anybodies take on this was.
