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.

I bought the amp a few weeks ago and it worked perfectly for a couple of days and then for some reason the controlls just froze. the tap tempo light went out and the channel control light stayed the same...


Exercise your warranty IMMEDIATELY since you just bought it! If you bought this used, you LIKELY bought someone else's problem. The problem is likely in the digital effects area... probably a bad cable contact... but if under warranty DO NOT mess with it... return it for replacement or repair.

I do not see any inputs to connect a subwoofer to my Onkyo A-9555 integrated amp. I would like to know if it is possible to connect it and what kind of subwoofer should I buy for that wit the best...


You amp has no OUTputs for a sub, but if you really want to attach a sub you'll need to get one that is self-amplified and accepts >>>stereo<<< High Level or Speaker Level inputs.

Otherwise your amp's volume control won't also control the sub's volume.

You would feed it full-range audio from the speaker terminals on your amp and its internal amp would use that to develop its own power output for the sub.

Here's one example.

Well, If You've Had It For Four Years, It Definitely Sounds Like Your Router Has Died So To Speak. Most Routers Only Tend To Last A Few Years Of Being On Constantly. I Would Suggest Buying Another Router Because The Cost Of Repairing This One Really Isn't Worth it. Good Luck, Brodey
