Yamaha receiver 7.1 not working

If you are using a 220V-240V appliance at 110V, you will need a transformer. If you are using a 110V appliance at 220V-240V, you can also use a transformer but may be able to get away with a (cheaper) converter though not with all appliances.

you said it says takes 110,im thinking that means 110volts
the might be flick switch near the power with 2 voltages 110v & 240v stick it on 240v, if not,then you need a transformer.

for a start - if you want correct answer, then provide model, original voltage. if i am judging it from the picture this is skill floorboard saw made for us market (110/115v 60hz), you cannot rewire the motor - full stop! purchase step down transformer 240v/110v 6amps to 10amps, if in australia - this transformer will set you back about $60.00 if in euro, this transformer (depending on country) will cost you anything between 40euro and 60euro. transformer will have cable on one side for connection to the main and socket to connect to the saw cable.

you can modernise this arrangement by permanently mounting the transformer on the saw (there is enough room on the end of the runner to mount it there), cut the cable to sufficient length and connect it to the transformer on 110v side, leave as is on 240v side.

YOU CANNOT REWIRE FROM 240V TO 110V, NOR FROM 110V TO 240V to do so you will need to rewire rotor as well as stator, and that unfortunately is not really easy job... i know i was doing that about 50 years ago...

if you find this answer helpful - do not hesitate to vote..

The only way would be a voltage selection switch on the back of the unit, or changing pigtail leads on the primary side of the power transformer.

Specs for this router says it draws 15 amps .
15 amps X 110v =1650 watts

I doubt that converter would last very long before going up in smoke

No, you need a step up transformer, (110V input 240V output)

Can you check the power transformer, voltage & resistance.
You may have to unsolder some components to test them...such as the rectifying diodes and the transformer.  I believe that the outputs from the power supply board are all DC voltages.  Is there all so a IC chip on the power supply board?  Does your insurance cover lightening damage?

There are two systems in use in the states
110v dryers are available that fit a standard 11v 15a socket
110/220v fit the oversize 'dryer' sockets, and they are two 110v phases 90 degreees apart
the motor runs of a single phase 110v.
there is 220v between the 'outside', the active lines of the two phases, at any time, but it is not useable to provide mechanical power as a single service, due to the complicated shape of the wave form when you add out of phase voltages together, but is ok to drive the heaters, they have no mechanical efficiency requirement
A 2 phase 110v heater it means 3kw can be supplied without a 30 amp circuit
but it becomes difficult to use a single phase 220-240v transformer to provide 2x110v 90degree 2 phase current unless you specially buy one in. .
High power applications in 220-240v are generally supplied by 415v 3 phase 60deg supplies,

Any transformer would be onsellable at the end of your posting, to your replacement, who would doubtless be in the same boat as you, with a heap of 'stuff' that needs to run.

UK Aus NZ may be sources of transformers, or dryers to suit.
check with Australian UK NZ suppliers as well as local Indian ones, as those countries are also nominal 240v single phase home suplies and they may have (1) the dryer, or (2)the transformer to suit the 110 2 phase dryer

all you needs is a step tranformer from 110v to 220v ac
