This is a project that I made for the EZ125 amplifier with quad KT88’s. This simple project makes it easy to get the bias set quickly and correctly. Each digital meter is color coded to the matching tube socket and colors match the wiring and pins to keep things simple. This was made in a small die cast Hammond chassis with the digital volt meters from eBay.
