Step down transformers detrimental to SQ?

MillerCarbon,

Your spreading some ignorant nonsense.  Most places in the US have close to 120VAC - and if running an apparatus with a 100VAC primary winding you will end up with 20% over voltage on the input to all  internal DC regulators in it.   This can be a serious issue because the regulators now will have to dissipate an additional 20% of heat and if marginally heat sinked,  this is trouble.

Most definitely use a step-down transformer, even better if you can find one with isolation as well - this will produce cleaner AC power to your amplifier thus resulting in higher SQ.

An equally important concern is if it is 50Hz or 60Hz current.  Running a 50 Hz unit on our 60Hz can cause overheating. (If it’s 50/60Hz rated, you are okay as far as current goes)

Actually it is easier for a transformer to run on 60Hz than 50Hz so that would be a non issue.

@erik_squires Thanks for the tip that is an amazing price...

Thanks all this has been informative.

You can get a bucking transformer for less than $50.00 that would do the job with many amplifiers. You might have to spend $100 for a really big amp.
