power supply

Pls advise is there any problem of incoming 230v to handle 220v power amp

Hi
please look in the manual of the power amp that will state the operating range . Usually manufacturer will specify +/- 10%

IMHO, if rig is rated at 220VAC, then 230V input will be quite alright, but I'dl feell jittery if input at 240V or more (depending on TNB incoming and may be different amongst locations). Best bet is to get a great quality regulator, set it at 230VAC constant and sit back, regardless if equipment is 220 to 240V specified input. If one is handy with electronics, investigate the probabilities if the rig can be switched to 230 or 240VAC at least. Best bet is to have quality regulator if you value your equipment.
My 2 sen general opinion.

according to md of isotek, fluctuations of plus minus 10 per cent of rated voltage is ok. modern components are designed to handle this range of voltages.

Not entirely. I've come across tube amps that don't sound proper when voltage dip to 10% below from 220 to 230V. Why?, there's many tube amp that don't have DC power regulation and tubes can't even heat up to optimum. Those amps will sound distorted. Most modern analog and digital equipment are almost immune to 10% voltage dips.

"modern' components does not include tubes, eh?

Normally, it would be rated at 220V, right? So that means anything in between 198V to 242V is still ok.

Then, spells trouble. Mine normally exceeds 243V. At times 245V. It could potentially spoil or shortened the lifespan of the equipments in the long run, right?
