I have a 77 Music Man 212 65 with a US 120 power transformer. I am trying to decide what power rating of voltage converter (240-120/UK-US)I should use on a UK supply. The plate says 120V / 1.6A which is 192W so is 200W Voltage converter enough or should it be 300W for headroom or even more? | ||

Here's an easy way. To your answer, no. Look at the fuse rating on the amp and use THAT for your computations. 4 amp at 240 volt is something like almost 1000 watts. Don't know what your amp pulls as max but even a little fudge on THAT would be a good thing. http://www.onlineconversion.com/ohms_law .htm | ||

HMMMMM-after I posted that, I realized that tha current consumption will be based on 120 cvolts, not 240. You will still need 450+ watts to use safely. | ||

Thanks Mike, I have a 5 amp fuse so I guess the max cut off before the fuse blows is 600W so it probably operates at ~300-400W. Anyone using a converter for a music man amp? | ||

Actually the figures I gave above are correct 120V * 1.6A which is 192W. Just talking with a local amp repair guy and he said rule of thumb is 3x the amps output wattage so thats 65Watts x 3 = 195W rating. So I'm good with the 300W Voltage converter. |

Power consumption
Hi all, I have a mm 112 rd one hundred 120v and need to know what the power consumption in watts is as my voltage is 240 and require a knock down box the fuse on the back is 5a many thanks
