| Help with static from B15R

Just a few days ago I brought my amp in to have it serviced to a well known and respected luthier here in Chicago. He replaced the two power tubes. Today I plugged in for the first time and there's a great deal of static and hiss coming from the speaker. I haven't changed anything else. The power cord is grounded into a power strip with a grounded plug. Does anyone know what it could be?
In the past when I use my wah pedal too closely to the amp I get a radio sation through it. Maybe that's relevant? Maybe just the speaker is blown? |
