Just a thought, I wonder if Frank would make his equipment rack mountable. Those old Carver you see on the floor, they were not built to be mounted on a 19" rack, I tried, the handles were there for looks.
The Japanese stuff, they were precisely built to be mounted on 19" rack.
Just imagine a Ultra550 with handle on both sides, with that studio look.
Frank could call it "AVA studio custom" Ultra550. How about it?
