I have an old SeaBreeze player (I think the motor is siezed). It is interesting in that the turntable is free spinning, with a rubber wheel coming up through the chassis to turn the record, and it slides in and out for the two record speeds. It has a valve amplifier that has a 25EH5 valve, which derives the filament supply from a tap on the motor. It has a selenium plate rectifier, and probably a Plessy branded dual capacitor.
Most portable record players sold into the 1970s used pretty well the same 25EH5 amp system. My mother had a Sstereo player that had 50EH5 tubes, whose filaments ran in serial with a ballast resistor from the 110V supply.
