Great work as always. I always miss the stuff on the community sections on channels, notifications don't always work even when full notifications are switched on.
I didn't come across the Luxman brand until I was at college in the mid-90's. The sound studio on the media course had a pair of Luxman cassette recorders. I don't remember the model number or much about them, but after doing a quick Google search I think they might have been Luxman K-250s.
