I have come accros these, DC mains record players,many had universal motors with a brake governor.There was a record player that used a shaded pole induction motor,the valves were series connected with an extra pair of UL84,these were only switched in circuit on DC,they produced a 50C/S to feed the motor,on AC mains these were not used.
Most of the DC mains sets I have worked on were 100-120,/200-250V,the 110v versions were mostly for marine use,since most small ships are 110V,while larger ships were 220V,although many of the smaller vessels are now 220V,its a lot easier to run a TV then!
