I was just wondering if anyone could tell me why it is that power conditioners are so commonly used with racks but not with tube amp heads. Are heads not damaged by power surges and brownouts? I recently ordered my first tube amp (an EVH 5150 III 50W) and was wondering how best to care for it. My house is afflicted by frequent brownouts and occasional power surges and I was wondering whether the amp is equipped to deal with these occurrences or whether they will ultimately cause damage to the amp. If this is the case and these power inconsistencies will damage the amp, how can I better protect it? Would a power conditioner be an effective solution? Does anyone use power conditioners with their heads? Hopefully my post is okay since I'm new to the forum. Thanks in advance for any advice.
