Power conditioner for a Vale Amp

[rkumarblr]

Is it good idea to use a power conditioner for EMI and RFI filtration to the input power of a Valve amplifier ?
Most commercial power conditioners are not worth the money.
There is a simple circuit design which is a modification of Jon Risch original design referred to as Silk 230 V AC filter.

The power lines in Indian homes is known to be noisy even if its a dedicated power socket and line.
So is it OK to use a power filter for input power into a class A integrate valve amp all other components like streamer, DAC etc having internal filters and linear power supplies.

Thanks

A lot of folks including me, do the exact opposite. Sources to conditioners and amplifiers direct to wall. Though a few friends are using Puritan PSM156's with their SS amplifiers, and are very happy with the results.

Mainline noise now days is because of widespread use of SMPS. Cell phone chargers, laptop chargers, etc. They all produce noise little above 20 kHz, but it affects the quality of power available

The term 'power conditioner' is not well defined or regulated by any norms or legislations. Almost all power conditioners for audio use are snake oil and glorified LC circuits with fancy display to display you the voltage, etc. The only real good power conditioner would be either your own generator or something that generates 230 v AC from lead acid battery. One could also convert AC to DC and convert that back to AC using a good amplifier.

The best approach would be to get an isolation transformer. Isolation transformers help to improve power quality by decreasing the amount of electrical noise and providing a more consistent voltage output. This helps ensure that any device connected to the transformer receives clean, consistent power without any interference or fluctuation in voltage. I think @ishmeet73 uses an isolation transformer. He could provide more information on this.

Interesting will read up on this. If you are aware of any brand or product please suggest for use in 230 VA 50 Hz AC supply

I see power conditioners are a staple feature of pro stacks. Pro users generally buy stuff based on commercial consideration right, why do they buy them then

I know of two implementions. @Yelamanchili manohar has a power conditioner from PS audio that converts AC to DC and back to AC. Theoretically this will be better than the LC circuits. @ishmeet73 uses isolation transformer. Isolation transformer cannot reduce the noise to zero, but can significantly reduce the noise. Avoid the LC based conditioners. They can generate high voltage transients and can ruin your precious equpment.

Unfortunately the PSaudio power plant is dead sir . Iam using an audioquest niagra 1200 for the source components for now. But Puritan is better than audioquest.
