Alright guys, i know one of the ground rules of using a tube amp is to have it connected to a load before turning it on. I stupidly forgot that i had connected my other head to the cab i was going to use. So basically, my AC30h was without a load when i turned it on. now here is where my question begins. I left my amp on standby for atleast an hour, thinking i was going to play it, but instead something came up and turned off the amp once i came back. Worst of all, this happened two days in a row. when i went to play it i realized it was not connected to the speakers and freaked out. Regardless, i connect the load and begin to play it, and it sounds alright. i cant 100% put my finger on it if it sounds somewhat off from before i did this stupid thing, but the one difference is that there is a crackle when you turn the master volume from 0 to about 1.5 in the dial. then its fine. Never did that before. also a slight volume spike when going from 0 to 1.5, again never did that before. Let me know your thoughts on this, (ASIDE from calling me a DUMBASS), experiences, or what not. Do you think the tubes would have taken the hit or the transformer takes most of the hit when this happens. Since it was only on standby, could that mean less harm was done????. Thanks guys.
