Does anyone know where I can get one of these?

I have a 601 that has been in storage for about 18 years. I was saving it to use for a "museum". The power supply burned up a 100 ohm resistor when I plugged it in yesterday. I looked back in this forum, and it looks like someone posted about this same issue a few years back. I have a schematic and there is not much to it, but I don't have a component tester (got rid of that and the O-scope a long time ago.) I would just be replacing components if I attempted to repair it. I'm not sure it is worth it for a display piece.
