Hello,
I have been in US and brought my US amp with me) but it is not compatible with Asia AC which is 220V 50HZ
I found one converter in local market marked as 250Va 220-110V and the other 50Va 220-110V do you think one of converters are enough for to drive my amp ?
my amp is Pioneer SX N30AE Elite seems 240W rated for AC power.
King Regards,
Turkel.

There are no any switch on back of the amp, and there are big transformer with small smps for switching on. So I think it is only 110V, how can I get its schematics, google have only manual((
It is user manual and there are nothing about AC voltages, only I see that, it is 220V and 220W device.
It should be a 110V device if you got it in the USA.
Open it up, trace the primary side of the transformer, see how many wires are there.
Take a picture of the track side, parts side and ID plate, post them here, you will get answers to your question..
I would use a 500VA step up transformer if needed, not much difference in price, it will run lightly loaded, but with better performance under peak loads.

Might not be correct manual, Pioneer might do IP steering or whatever it's called. A US IP address might access a different manual.
Better to check at the usual manual sites, and sellers like hi fi shark, that might be a better way to get more information.

German market 220V model, made in Malaysia.
Be advised that most 220-120 voltage converters convert only voltage. They do not address the difference in 60 HZ vs. 50 HZ frequency. Some transformers designed for 60 HZ do not like being driven by 50 HZ due to higher heating. 50 HZ transformers typically have more laminations, making them more expensive. You may be fine, but it's something to consider.
I haven`t disassembled it yet, but from internet pictures I see there are big transformer with 2 input wires. so this transformer only 110V right? 🙁

Given its age, SMPS is more likely, then a transformer for changing voltage would not really be affected by frequency, the SMPS will tolerate frequency changes on the primary side.
Some computer SMPS could be changed for voltage quite easily, neutral common, and one big cap for 110V, OR two for 220V operation.
I mean the big filters before the chopper transistors.
Was it working earlier, or you got it as is?

Yes it works great, never had issue with 110V AC.
I will diassmble unit this weekend to see if there are any extra input wire on transformer for 220V or not. if yes then we can discuss here conversation of unit to 220V.
But, in anyway, I think I need 220V to 110V 250W transformer and that is all :S

Dears, I got 500VA 220V -> 110V converter and it works OK now 🙂 Problem solved!, but not in ergonomic way, as that converter is really big :S
I am still stack on if that would be possible to easily convert unit to native 220V. Please see attached pictures, most of the PCB units are 250-310V but fuse is 125V. I was also not able to define the specification of transformer by it is part no. what do you think, by replacing fuse with 250V one may solve my issue?

Not how fuses work at all. Your existing fuse is also rated 3.15A at 250V no matter what is written on the PCB.
Maybe a better picture of the transformer clearly showing the leads?
