so i'm in a band, and the other day we tried playing a show, and we were gonna use my friends new tube amp, which we had been practicing with for a while, and it was working finehowever when he flipped the switch on, it started playing radiowe were really confused, and we thought that we lucked out because their was a guitar shop across the street, and we thought they could fix ithowever they said that there is nothing that you can do about it.however i don't believe thisis there anything that we could do, whether it be fix something in the amp, or to buy something that will stop ithow do we get his amp to stop picking up radio?
Would you care to try asking your question in a way that makes at least some sense? Preferably in a language spoken by at least some Earthlings?
There are LOTS of things you can do to resolve this problem, and although cheap design is often a problem that can lead to this symptom, it is not the ONLY problem - sometimes strong RF fields just overwhelm a piece of equipment and you need to do some troubleshooting to see what to do nextStrong Radio Frequency (RF) energy can 'insinuate' itself into many different types of electronic devices from telephones to guitar ampsYou need to isolate things to determine where the RF is entering in order to determine what can be doneStart by unplugging everything from the amp, and then one item by one item, plug in each microphone, guitar and whatnot until the interference startsIf the interference starts the first time you plug anything in, unplug that item, and plug something else in to see if that matters You can install isolation 'chokes' in the lines to prevent RF from getting into the amp once you determine what lines are causing the problemsYou could also just move the amp (sometimes just moving it a couple feet one way or the other can help), or you may need to shield the amp with metal (Aluminum foil around the case in such a way as to not block air vents often does the trick) if the problem is really bad How close by is the radio station that was interfering? Do you notice the problem anywhere else? You said it worked fine during practice, which implies that this IS location dependentIf all else fails, find a good OLD FASHIONED TV repair place and the technicians there will know what to investigate to resolve the problemGood luck!
