Strange clicking noise when I turn on my amp

    Whenever I turn on my 400+, it clicks about 3-4 times and then stops.

    I let it warm up for at least a minute before I turn it on.

    The clicking doesn't really bother me, I just want to make sure that nothing really serious is going on.

    I've had one open when I owned it, and I'm fairly sure there aren't any relays in there. Yeah, I just checked the schematic - no relays.

    Could it could be a dirty tube socket? The current can burn the 'crap' off the pins and make popping noises.
