easy, amazon prime, $30. have it tomorrow. https://www.amazon.com/VCT-VT-200J-Japanese-Transformer-Converts/dp/B081TLK87S/ref=asc_df_B004S2COIC/?tag=hyprod-20&linkCode=df0&hvadid=226131567976&hvpos=&hvnetw=g&hvrand=15901971708719460343&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9003512&hvtargid=pla-390921810426&th=1 they have several, they vary according to the amount of watts the device draws. Voltage must match, and watts simply have to be enough for the device(s) it feeds, CD player is not gonna need more than this 100 watt version.. A device will only draw what it needs, like a 60 watt bulb draws less from a line rated for much much more. Volts are volts, i.e. Apple's 5 volt chargers. the amperage is low or high (amperage is relative to watts), so they keep raising the needed amperage so you need to keep on buying new adapters. And, they keep changing the connector types, the ........ |
Stepping down the voltage is the correct solution. Running it at 120 volts can cause problems... for example if a secondary voltage somewhere inside the unit is, say, 34 volts and there are 35 volt capacitors, then 120 volts on the primary will increase the secondary voltage above the rating of the capacitors and...poof. So unless you are dead sure about the voltage ratings of the parts inside, step down the voltage to where it is supposed to be. Simple physics, not misinformation. |
If it has a switch mode power supply, odds are it will be okay at 120/60Hz, though if truly designed for 100V only (rare) it could have issues with component tolerances and fail early. If it has a linear supply, you could overheat things. w.r.t. this post below, odds are it was built with universal 100-240VAC switch mode power suppl(ies). It is sensitive, but would likely use off the shelf supplies. millercarbon3,254 posts03-02-2020 3:02amJust to give you all some idea how absurd it is to think a few volts matters, I once ran a lithotripsy machine designed for 240 on 120. For you mathlexic types that's like half the voltage. That's a complex and highly computerized machine that generates shock waves that break kidney stones. Its a lot of power, precision, and an incredible amount of sensitive electronics. More pumps, motors, servos, microprocessors, transformers and high voltage power supplies (in excess of 60kV) than you can shake a stick at. You would think the thing wouldn't even run, or at least would throw error codes, or work but weakly, anything but what happened, which was nothing. Worked absolutely fine. Didn't even know about the voltage until after the fact. |
