Mid-century vintage, Knight model KA-25 stereo amplifier for restoration or parts. This amp was originally built from a Knight Kit as there is a "Custom Built" label with a name in the case. We've plugged this unit in and it powers up and the tubes glow, but there is wear and flaking/peeling to the paint in areas along with some light rust.  We don't know much about this and so we're selling it for restoration or parts.
