hey, i'm a dumbass. today i was jamming and i had to move my amp to a different house. once i had it setup, i flipped the power switch on, and left it in standby for about 3-5 minutes. then i turned the standby on, and couldn't figure out why i didn't have any volume. took me about 15 seconds to realize i didn't have the speakers plugged in. i turned it off, plugged em in, then turned it back on. jammed for an hour... seemed to work just fine... it was a soldano decatone head btw. I know, i'm a dumbass. that said, could the amp be damaged? I mean, if anything had happened, would it be painfully obvious? or could it have like, i dunno, killed 50% of my tone forever or something? do these newer heads have any sort of mechanism to protect against running no load, like the line 6 heads that disconnect whatever when there are no speakers plugged in? like i said it sounded fine after i plugged the speakers in, but now my brain is going and i want to technically know what occurred. please help. thanks.
