    AC Power Issue Empty AC Power Issue

    Hi all, and I hope everyone is staying healthy and home enjoying music and their VTA amp!

    I have only a 100A service and when the window unit A/C is on, running anything other than the HiFi tends to trip the breaker. Today, the vacuum tripped it. Being in a manufactured home for the past 12 years, I've come to realize the shortcomings, especially in the AC department. Sigh. About a month ago, the AC went off/on/off/on/off and power was lost to the house. I later found out a car hit a pole. Fortunately, my ST-120 was not on either time. Unfortunately, I cannot separate the A/C from the HiFi sharing the same circuit. I want to protect it beyond the diode mod.

    Sooo, I have an APC BX1500M 900W uninterruptible power supply on the way which is a good time for me to now ask if there is any reason I should not use this for my HiFi equipment or specifically the VTA amp?

    I ask because I don't see them advertised in the audio mags, and there seems to be little conversation. I'm a bit baffled as I'm used to UPS' being used for computer and networking equipment. We used these not just to keep data flowing but more so to allow for a graceful shutdown. Seems like a good option for HiFi gear.

    Most likely a good investment.
    This will also protect the amp from power glitches as the APC will supply power during power glitches.

    That particular unit is great with solid state electronics. Not so much for tube based as the sine wave is not a pure sine wave when the battery takes over. This unit may be a good alternative:APC with Pure Sine Wave

    Thanks! I'll get the sine wave model.
