I built a a fairly serious system during COVID. A few weeks a I was left with a blown out tube amp after a brown out. Tube amps don't like this stuff. Not the first time. They blow reciters and key components when voltage dims and then surges. I firmly believe it is the utility. I've also been told I have a loose leg either on my local panel (condo) or the building panel. Have an Electrician coming out to check my panel (condo) Based on this chain - I'll need to have building management do a test on the building panels. Any other ideas I'm looking for a solution before before I spend major bucks. UPS backups don't work - these things need pure sine waves to behave. Thanks. I appreciate all helpful responses.
Seems strange that you'd go straight to your panel when they make high-end power surge protector for sensitive audio gear. Have you considered something like this: https://www.turntablelab.com/p...
But, besides that, what system set up are you rocking? I jumped into this world (dipped my toes mostly) at the start of covid but could not source my choice TT at the time. I wanted an AT120 but had to settle for AT60. Now, 4y later and 200 or so records deep, I've seriously oogling over a Fluence rt85.

But that Lyra Delos yellow cart is serious business at 2k ea.
Have a look at Nottingham Analogue the legendary Tom Fletcher. Yes I'm running a Lyra Delos - my second one - on a Nottingham 294 Space Deck. There are several interesting things about NA decks. 1/ they run on seriously low powered AC synchronous motors. The motor is not powerful enough to spin the platter. 2/ the deck weighs 75 pounds. the platter weighs about 30 pounds 3/ the platter acts essentially as a "flywheel". The motor is only there to keep the speed stable. To start it it - you need to spin it by hand. The deck uni-pivot tonearm is a brilliant piece of engineering. The antiskate design simply blew my mind when I figured out how it worked - pure genius. The rest of the system is as follows: Yoshini EAR 834P tube phono stage- designed by Tim de Paravicini - legendary bit of British gear - here to stay. Roguen Audio Cronus Tube amp - designed and built in PA. Have an issue just call them and they pick up the phone. Digital side: Antelope Audio Zodiac plus with a separate power supply. Antelope builds digital shit for the recording industry. First rate company. Speakers are Canadian built Totem Hawks- they are awesome. And then some bespoke cables.... To the post - Tube amplification is very sensitive to power. and protection from power surges is not as simple as surge protection. They require clean stable power and a pure sine wave. Audio quality power regenerators usually contain massive capacitors and basically start at about $5K. Thus my question. This system is good - It is holographic - the sound stage is enormous. Are there better? Yea of course but to upgrade from here is a massive expense. Let me know if you have any other audio questions. Oh yeah I'm building a 294mm tonearm.

SM... I am seriously nerding out over the set-up. Thanks for sharing even though this trouble-shooting is well above my pay grade.
More directly to your point - after speaking with several knowledgeable people - brownouts can be caused by several things, mostly a lose electrical leg on a panel. these are violent events with cause arcing and in some cases cause fires. So it is is either in my local condo panel - which was recently replaced so I wouldn't be surprised, or the building distribution panel, or the utility...... We'll see. Electrician coming to checkout my local system. Man HiFi gets expensive....

I'm curious to see what sparky says about it. I'm not an audiophile (deaf), but the power issues are very interesting. You might consider looking into getting a power conditioner (isolation transformer?) and then adding a UPS to it downstream where it could get PSW AC. Would be significantly cheaper than a $5K capacitor rig.
A UPS PVS may be the way to go. The problem is most are simulated perfect sine wave the the price starts getting very close to the 5K threshold of as high quality unit
I don't know about surge protection, we've had some issues with wiring when installing house wide speakers; I admire your setup, I grew up in a silent house, never knew why. This speaker looks awesome, don't know about sound quality though https://archinect.com/news/art...
Hi fidelity Voltage protection - Architect Audiophiles?
Anyone?

I know Transparent from their audio cables but nothing about this speaker
