Buzzing bass Amp combo

I have a tnt 115 bass amp combo from peavey. Its probably 7 or 8 years old. Lately when I turn it on there is a loud buzzing sound. When I turn up the volume it gets higher, when I turn down the volume it gets quieter but it still very loud and never goes away. I unplugged my bass and the sound is still there so it is definitely the amp. I feel like some of the components in the circuitry are bad. Please let me know if you know what could be making the sound. Thanks

The problem you have mentioned is a common one with old sets, but it also occurs in new ones also, though not frequent. You can fix this just by changing the electrolytic filter capacitors in the power supply and sub filters on the amp PCB. The new capacitors should be of the same or higher voltage rating and same capacity rating as of the existing ones. And as it is such an old one, it is better to change all the electrolytic capacitors to avoid any further problems.

Peavey tnt 115 blowing fuses

your either overloading something cause that's what pops fuses. My guess is that what your plugging in or into has a ground issue. I'm wondering if it does it with nothing plugged in at all. I would say if you have nothing in and it does it, you need to find where the ground issue is. that's my best guess

Have you tried to open , if so does it have protection fuses or if are they still good
Does it have a fault protection indicators like leds if so

If the above don't apply check the output device but first comfirm that both vee a vcc is reaching the output devices
