It's most unusual to see the amplifier/speaker compartment sealed off like that. (Heat build up, poor acoustics?) This looks like the UF89, UL84 version with a mains transformer. We do not know if this is fully isolated or just a filament transformer, and yes, Regentone did use these with "U" series valves. The low speed might be debris built up on the (stepped) motor spindle, hardened grease or a partly seized platter. When working on this it will be easier if you lock down the autochanger deck plate down using the transit screws. Wnen it comes to DC voltage measurements, it might be best (and certainly safest) for an expereienced person to check this over for you. Your unit is now 63 years old!
