Vintage Tube Amp

This was found in a storage unit so I don’t have that info on it. It powers up and works. One tube may need to be replace or tweaked. I believe this is a custom? That used the 4001 to make a head unit? The serial number is super low at 00834 so I also don’t know if some. Where made like this. Very hard to find information about.
