    i have a Peavey TNT115 (Old US made, built like a brick sh*t house!) and recently, there has been a constant buzzing, even with the gains turned down

    this amp has a POWER AMP inpute (which bypasses the pre amp, and send the signal straight to the power amp) and a PRE AMP out (Which send the pre amp sound to an external device)

    If i plug a jack lead into the power amp input, the buzzing goes, and i can play with no buzzing at all (just not much level!)

    But if i connect that POWER AMP input in the PRE AMP output of my Peavey Combo 115, the buzzing comes back.

    Also, if i connect the pre amp out of the buzzing TNT115 to the power amp in on the Combo 115, the buzzing sound is also sent to the combo

    Im thinknig sound kind of grounding issue, if so, how can i fix it

    please note, this has only occured very recently

  2. This could also be a sign of failing power supply caps. The gain is higher in the preamp so it will boost the noise from power supply as well. May just be time for some new caps?
