Marshall amp for 110V, plugged in 220V. What to do?

8 years ago I bought a Marshall amplifier in Sao paulo, Brazil, and used only for a few days. I packed it in its plastic bag in my home. Sao Paulo mains is 110V. The vendor made it ready for the town customers.
Now I am back to my city home which mains is 220. I don't remember using transformer 8 years ago. The first thing I did was to plug into the mains. I heard a faint noise but no more afterwards. The amp sounds dead as there is no static when the classical guitar cord connected to the am is swung.
I am wondering if I damaged the amplifier or just a part of it. That is, I wonder if there is a fuse to protect for such idiot action. Apparently there is no visible apparatus to suggest changeable fuse.
I don't want to send to some adventurer who claims to fix and make it worse. On the back of the amp says not to open it. What can I do?

    Hi...

    The amp will need to come out of the case.
    What model Marshall is it?
    I could tell you where to look for the internal fuses.

How do I convert my adcom 5400 from 110v to 220v(moved to Australia)


You need to move the jumpers, then change the Mains Fuse to half of what it was in the US. This is because it remains the same wattage as it was, but now has twice the line voltage applied. Enjoy! Thats a nice unit.

How to change 110v to 220v on sonance cinema 260 subwoofer amplifier


I suggest contacting the manufacturer as there may be an internal "reconnect" that would allow 220v operation. Good luck!

I have a marshall mg250dfx amp & have just got a marshall mg programmable footswitch for it model number is pedl-90008 but when plug it in nothing happens is this pedal compatable with my amp/


According to the Marshall site, the PEDL-90008 is not compatible with your amp. Only the 2-way foot controller that came with the MG250DFX is compatible with it; that foot controller is the PEDL-90004. See http://www.marshallamps.com/product.asp?productCode=MG250DFX&pageType=SPECS . If you need to replace the foot controller, it appears to be available at several vendors. Musician's friend is one online store with it in stock, http://www.musiciansfriend.com/amplifiers-effects/marshall-footswitch-for-mgdfx-amps .

The PEDL-90008 is compatible with amps in the MGFX line listed here: http://www.marshallamps.com/product.asp?productId=174 . The second column is for the PEDL-90008.

I wish that I had better news for you.

Need a power transformer from 220input to 120output


What you need is simply a power converter device that knocks the power down for your device. Look for a UK (European) to USA power convertor on somewhere like Amazon.

Accidentally plug 110v dryer into 220v. it wont start anymore..what's wrong?


The dryer would have burned off the coils as the voltage is double of the operating voltage that was designed. ALl what can be done is to open and find out the break in the heater resisitor winding . These wires act a fuse and would have just burned out and lost the connection. find it out by a continuity test and connect at this point by joining , twisting. Now test the continuity and test on the 110 volt. it must work hope fully if the motor has not burnt out too. Hope you try. Good day..

I accidentally plugged my 110V amplifier to 220V outlet.It has no power anymore.what possible solution for this. Thank you very much. Do I need to replace the rectifier in it's circuit?


Hi and welcome to the site,

Initially, on a completely dead Sony TA-N9000ES, primary suspects to be checked would be:
  • 8A F1 fuse;
  • primary winding of T1 transformer;.
  • fusible resistors R816, R817 and R818.

Good luck and thank you for asking.
