Does it have a headphone output ? check that. Also, check the INSERT jack on the back. Plug and unplug a plug (sic) into it several times. They become rusty sometimes. Luck ! If the headphone sounds, your problem might be the output transformer or the 6L6 output tubes. Have you checked your speaker...? Luck.

Sounds like a sure sign your tubes are on their last legs. I'd get those tested before doing anything else.

I have a marshall JCM 900 when I plug in my foot switch and try to play it pops and cracks .I know it's not the foot switch or my guitar.I checked the tubes they look alright so what part is broke in my...


I doubt that you have checked the tubes... tube checker's are rarity now and you can't look at a tube and "tell it is alright". If you leave the footswitch out does it do the same thing?
The probllem could be many things...and you haven't mentioned how you tested the items you are exhonorating. A common problem is a noisy or broken INPUT jack. Musicians forget to loop the guitar cord through the handle and the cord gets moved and yanked sideways wearing the jack and often breaking internal parts. Yjos also goes for the cord to the footswitch as well. Cords and connectors/jacks are the common problems. Less common but frequent are damaged volume control pots due to damage when handling... including broken solder where these attach to the circuit boards.

I can turn it on and i hear the fan going...but it doesnt make any sound when i strum or anything...please help!


There are some basic things you can try before you suspect the amp. Does your guitar cord work in another amp? Is your guitar sending sound through your guitar cord? Without any thing plugged into your amp can you hear a slight hiss when you turn your controls up on your amp? Here is a link to some things you can do to troubleshoot the problem:http://www.geofex.com/ampdbug/ampdebug.htm Even though the info is for tube amps a lot of it also applies to solid state (transistor) amps like yours.If it turns out to be the amp and you don't feel comfortable working on it and have no one that you know personally to do it you are best served by taking it to a certified Marshall repairman who will have the tools, parts and schematics to help you.

Nothing is plugged in and the volume is down but when the amp is turned on it sounds like a airhorn going off


This could be caused by a few things but the first and easiest thing to do is have your tubes checked.Here is a link to a trouble shooting page that will go into more detail than I have space to do here:http://www.geofex.com/ampdbug/ampdebug.htm Please let me know if this helps.

This amp used to sound great, but recently it seems like it has no bottom end. The sound has become "cheap" and lacking the warmth it used to have. What can I do to fix this?


Take your amp in and have it checked. You might need new tubes. Have it rebiased and get them to check the filter capacitors in the power supply.
