Hey all,

https://soundcloud.com/nickmaynard/orange-crush-12l-white-noise

i was recently given this small practice amp by someone who simply said it was "broken". i plugged it in and was greeted by white noise. the guitar signal still passes through and sounds fine except this white noise is constant. it must be occurring pre-amp though because all of the knobs on the amp affect the tone of the white noise ( volume, eq, distortion all change the character of the noise).

i'm posting this sound clip with the hopes that someone can help me diagnose what the issue might be. could it be a bad rectifier?

just for reference - i hit record, then turn the volume of the amp up slowly. i then turn the eq knobs and finally turn the distortion and gain knobs slightly before turning the amp back down again.

any help would be greatly appreciated!
