Use of a 110 VAC to 230 VAC Step-up Transformer for CD player.

What is the impact, if any, of  using a 110 VAC to 230 VAC step-up transformer,  to run a European CD player that is not readily available in 110 VAC in the US? The unit is not switchable between voltages. I am not conditioning my 110 VAC power currently. Is there anything I should be concerned about?
Can you find a 'balanced transformer that will do this?
I have no idea
See my previous post on this subject. A simple step up transformer will work fine. I have had a lot of experience doing this over the years without incidents or degradation in sound quality.
Shouldn't I be concerned about the CD player being designed for 50 Hz , but  running at 60Hz. In other applications this may not be as important, but with high end audio gear I just don't know. Thank you for responding
I am trying to see if the manufacturer will sell me just the power supply, if that is all that needs to be changed. They are saying to send the unit to them and they will do it, but that will take weeks or months and add about another $800 - $100- to the cost, which I am trying to avoid. I hope that ypui are correct mgattmch. Thank you
Sound quality will suffer why would you buy a foreign unit anyway??
Foreign units are more readily available and frequently at a lower cost. If sound quality will suffer I am not going to do it. That is what I am trying to understand the impact.
OP -

A lot of transformers are dual-voltage. A qualified tech may be able to re-wired it internally to switch for you.

If the CD player is made for Europe and the US this is very likely.

50Hz versus 60Hz is only a problem with AC motors and stuff like Krell and Martin Logan equipment. This two manufacturers, I am sure there are others, install a frequency sensing chip in the power supply and will not allow the equipment to operate if you have the right voltage but wrong frequency, This is not true with older Krell gear. For example, I used my Krell KSA-250 in Europe and the States without issue, all I had to do was change some dip switches on the power supply to go from one voltage/frequency to the other.

AC synchronous motors, for example on TT, will not run at the right speed  if operated on the wrong frequency.
Ran 220v tube preamp using off the shelf converter with no discernable ill effects.
Get the 500w version.
Make sure you know the wattage of the 220V equipment, and get a higher wattage rated step-up transformer for it. For example, if the device is using 50W, get a 100W step up transformer.

I have a component that runs off of 220V, and I used a 50W step-up transformer with it. Turns out, the component was pulling more than I thought it would, and the plastic case was starting to melt!

Also, give your step-up transformer "room to breathe". One of the reasons the one I mentioned above overheated was because it was directly plugged into a Monster power center, and physically touching said power center, not allowing enough air to circulate to cool the transformer.

Now, I'm using a 100W step-up unit, and one of those short extention cords that you often use on a power strip to prevent a 'wall wart' from hogging all the sockets.

Eventually, I'm just going to replace the internal transformer to a 110V version.
@joeylawn36111 I also want to just swap 220v transformer in a Marantz CD63 (Philips CD100 rebranded). Cannot find 16V 28V dual secondary transformer though... Any tips on where to get one?

Sevs, sorry I don't really know. PLUS, I've discovered that sometimes you can't just replace the 220V transformer with a 110 version of the same output. My example above I said I was  going to replace the internal transformer to a 110V version, but when I did, I blew up the power supply! (I replaced the blown components, however, and re-installed the original 220V transformer. Safest thing to do in your case would be to get, say, a 100W step up unit like I did, so it won't overheat like my old 50W did.
