Look inside and see if there are any switches or connections labeled for
voltage.

If not, apply 120 V (the lower of the 2 possible voltages) and see if it
works.

I was given an old Sony tape deck. The original deck specs 110V. The
person who gave it to me, told me the power supply burned and he had it

fixed but can't recall if he had the transformer rewired for 220V...
Is there a way I can find out if this is to work with 110 or 220? Only
thing I have is a Voltmeter.
Thanks!
