so far the MB1 amplifier (12ax7 & 6aq5) and the small speaker power output stage (6aq5) are built onto an ugly custom stripped out chassis. its chopped up to fit neatly into the lovely old skyqueen cabinet. it sounds great even with it’s very temp/experimental control wiring. just need to drill and letter stamp up the panel, anodize it.. and finish the build. the ugly chassis looks like many 50’s european radios . those crazy germans made the ugliest most dangerous looking electronics …placed inside beautiful veneered plywood cabinets. u just dont see that stuff being made anymore. if anything has curves – safely assume it is moulded plastic.
