    Reviving this older thread. My line voltage goes from 118-122 (have seen 113 VAC to 126 VAC) so I have to chase my Variac all the time. Has anyone found any more recent solutions? One post suggests that running too far under voltage is bad for the tubes. I have the variac set for the highest swings so I don't pop the multi-cap on my ST-120.

    One solution is to install an UPS , I have a Smart-UPS 1500. It's a straight wire
    when the input voltage within limits, outside limits it will synthesize AC.

    I do use it for my computers however as the electrical net in sweden is fairly good and
    power outages is less then one per year. Mains voltage fluctuates ( today) between 233V and 240V
    which is fully acceptable for my stereo.

    I have a UPS but doesn't clamp swings adequately. It is a CyberPower CP1000PFCLCD PFC Sinewave UPS System, 1000VA/600W.
    Apparently the older ones had a button that took you into a menu that you could set high/ low - this doesn't. Even using the software attached to the UPS won't let you clamp until the line voltage reaches 138 VAC. Don't have a grand to spend on the other suggestions.

    JWB474, Who manufactures or sells the lower two items you pictured ( looks like Variacs that regulate output voltages independently of input voltage ) . Do you have names or model numbers for them?
