Marantz PM6004 Amplifier - Voltage Issue?

[karan.c]

Hello

I recently shifted to a new home in Goa where I am experiencing significant voltage fluctuations in the evenings. I suspect this causes my amplifier (PM6004) to go into protection mode as the standy light starts flickering / clicking. During the day, this doesn't usually happen. However, in the evenings I've noticed the voltage readings between 190-250. I reckon this be the cause?

My present setup is pretty basic: Mains > Belkin Surge Protector > Maranatz Amp + Project Turntable

Do I need to add a voltage stabiliser to the mix to ensure a steady supply of normal voltage to keep the amp running? If so, could someone recommend a reliable one under 5k if possible?

Apologies if this question has been asked before! Appreciate the communities guidance.

I'll wait for more knowledgeable experts to respond.

This is my set-up in Bangalore...

Mains--------UPS (1000kva)----------Voltage Stabilizer-----------connected to Amp, TV, STB etc.

Hope this helps.

I am using a Vguard digi 200 for several years now. You could try that

Does hifi equipment's needs to connected to stabilizer before connected to electrical socket?? I have no idea.

If there's low voltage, it seems there is a need. I've been recommended a Studio Master 2KVA amplifier. Wonder if it's overkill.

May I ask which UPS and Stabiliser you use?

UPS is APC, voltage stabilizer - I'm not sure, bought it a while back. It is one of those meant to be used with electronic equipments.

You need to add a Voltage Stabiliser for sure if you have fluctuations. Can you also use a electric tester and check if you see any feedback voltage on the amp body. If so then use a three pin connection and connect the ground wire to the body of the amp.

I faced similar issue and two of my Marantz amplifier started with similar symptoms and eventually the Power board had to be replaced.

You may not need the Voltage Stabilizer in the chain. Online/Line Interactive UPS comes with built-in Automatic Voltage Regulation.

Better to go for servo,

Is your home power connection a single phase or Three phase one?
I am experiencing something similar with my Denon AVR and had bought a servo stabiliser as well. Though not fully rectified it does tend to safeguard the device to a great extent.
Note: I have given my AVR to the service center to inspect on the random restart issue and most probably i ll get it back by this weekend.

Soundmaster 2KVA stabiliser seems to have addressed the problem! Thanks for all the input =)
