TD104 wall wart

The manual doesn't describe the turntable's operating voltage from a wall wart.
Can anyone provide that information?


Did you resolve problem about power supply for your Thorens TD104?
If yes please advise me because I have each problem.I have this turntable but without power supply.
Is not problem to make any but I didn`t know voltage, current and it is AC or DC.
Please help me with info if you know and thanks in advance.

TD104 wall wart


there´s a sticker on the back of my (destroyed) unit that says minimum 11V AC, max 250mA.

So any transformer close to these specs (11V-16V, min. 250mA) will work.

Sorry, didn´t see, that there already were anwers.

power supply
