This turned out really well. I wound up using a LAB 400 instead of a 440 as the switches were better placed for operation. The 400 is actually quite a nice turntable, I considered keeping it for myself instead. I installed it in an old 1960s Samsonite hardshell suitcase. The turntable fits nicely into the bottom half and the top half can be enclosed by fabric on elastic, so I installed the phono preamp there. I didn't want wall warts visible, so I took them apart and installed everything there as well, enclosed in masonite. The bluetooth transmitter runs down and hides inside one of the side pockets of the lower half of the suitcase, and it can be unplugged if someone wants to plug the turntable into a regular amplifier with a 1/4" plug adaptor. The suitcase closes and latches just fine, so can be put away when not in use.

Kind of an overkill solution, but a fun and easy project that works as well as I had hoped.
