Question bout cooking parts...

Post by Icetech »

Hi again.. feel like i been posting alot lately:)

Tonights story and question.... tonight is the first time i have really cranked up my amp (dumble on bassman iron).. the thing sounds amazing on 10's :) but the downside.. i was working on making myself deaf.. and i saw a whiff of smoke.. from the OT area..i instantly shut down and started looking around.. can't find damaged parts and amp works fine.. What im curious about is this, when a OT fries does it physically get hot? or just windings inside melt and make smoke?

I ran it loud again for a few mins, but didnt get the smoke again.. the power tubes have some brown burn spots on them, kinda like finger oil that burned onto the glass, but i doubt it would make smoke like that.. was just a little whiff or 2 that i saw...
