Not if it wasn't manufactured for an area of use that is running something other than 120 volts. If it wasn't imported then plug it in and go.

What is the rated wattage for the mastercraft drill

the wattage is on the plate attached to the drill and will still be the same as before you attach a step down transformer to get to the correct voltage
get a step down transformer that has a large wattage rating for 120 volts ( say 1200 watts ) as most 1/2 drills are 750 -1000 watts )
the wattage is for the rated current through the transformer and if the drill is of low wattage , it just gives the transformer a greater degree of serviceability in the duty cycle

I have a sansui stereo av receiver rz 7000 from 1990 which works on 110 220 230 volts and the receiver has a voltage selector on the back - I need to understand how to move the selector from 220 to 110...

Remove the fuse cover with a flat screwdriver, then pull the surrounding circular black plastic piec straight out and reorient it to show the desired voltage, then plug it in, insert the fuse and cap.

Speaker compatibility ( Just got this new reciever with 120 volts power requirement of the receiver, but in the philippines voltage standard supply is 220. can i use 110 voltage supply instead? and I dnt...

The most likely answer is no. Unless the power transformer is of the multi tap type and has a voltage selector window on the back panel... Most speakers today have an impedance of 8 ohms. The impedance is all you need to worry about when matching speakers. You can fit 8 ohm speakers to a 4 ohm system, but you cannot fit 4 ohm speakers to an 8 ohm system. It would overload your oputput stages and cause them to fail. It's best to match 4 ohm with 4 ohm, 8 ohm with 8 ohms.etc.

It powers off immediately when I turn it on


Thanks for using FixYa. From what you have described it seems the fault is in the voltage selector rotary switch, it’s the round voltage selector switch not the other one, because you'll notice that there are 2 voltage selector switches at the back. The lock might be broken so you couldn't switch the primary terminals of the main transformer. In other words this amp has 2 power transformers, the small standby transformer and the large main transformer. Try to press that round switch and press the front panel power switch. If it goes ON, then fix the center lock of that round switch. If not then you might have to replace the switch.

Please do accept the solution if the issue is resolved or else revert for further assistance.

I have a pioneer vsx-501. I can't get it to turn on. When i hit the power switch I get a mechanical click and the standby light comes on, but that's it. All the internal fuses are fine. I think the power...

have you fixed it already?
I have the same receiver with the same problem as yours.
I found the fault in the voltage selector rotary switch. I'm refering to the round voltage selector switch not the other one, because you'll notice that there are 2 voltage selector switches at the back. The lock was broken so it couldn't switch the primary terminals of the main transformer.
Basically this amp has 2 power transformer, the small standby traffo and the large main traffo.
Try to press that round switch and press the front panel power switch. If it goes ON, then fix the center lock of that round switch.
Hope it helps.

SR573... Does it support NTSC/PAL?.

There's no mention of either NTSC or PAL in any spec sheet.

This link leads to Onkyo and the rear view of the amp lacks the voltage selector.

The manual for the similar model SR575 says the North American model does not have the voltage selector. Too bad. Under the general specs for the variants of this family of receivers they list the following power specs. I have no idea where you have to go to buy one from the "Others" group.

Power Supply North American: AC 120 V, 60 Hz
European: AC 230 V, 50 Hz
Others: AC 120/220-240 V, 50/60 Hz
AC 220 V, 50/60 Hz

Some aliases for the SR575=

You could do what I did over 30 years ago. Join the Army, go overseas and buy one in the PX. Every HiFi product we bought in the PX in the 70's had the dual voltage feature.

FM Frequency Steps


Appreciate the "Ask Me" and my compliments on the choice of an Onkyo TX-SR605.

Onkyos are not very common in my country. Often, they are imported from the US and since we follow US broadcasting standards, there would be no need for modifications particularly with the tuning steps.

To my knowledge, most manufacturers would be coming up with a single model but with:
  • variations of the firmware to suit the region/country of intended use; or
  • a service menu where the country/region of intended use is selectable; or
  • jumpers/bridges in the logic circuitry.
Simply, this is similar to having the unit with a voltage selector at the back for 120, 220 and 240 or an auto volt 100~240.

As to your concern, pls check:
  • if there is such a feature in the menu to change regional settings (the user manual may have this information);
  • firmware update, but rather than select US, pls select one appropriate for India;
  • a service manual where the logic circuitry would be shown and if there are movable jumpers/bridges for the selection of intended region/country (warranty may be void).
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Audio Receiver Video selector problem

Hi jmiglio48

Most high end Yamaha s used Alps devices for switching and attenuation. The problem you face is probably caused by a noisy switch contact. They are a little hard to get into to contact clean, I have managed to spray the internals of this type of switch before by using a pin vice with a 1mm drill to bore small holes into each bank to get access to the switch contacts and then spray internals with contact cleaner/lubricant. As the switch is hermetically sealed, they are considered to be more a replaceable part. I suggest you do an inquiry with a Yamaha service agent in your locality to see if a new switch assembly can be sourced. I have replaced one here in Australia before(cost about $120 for the part), but current availability will depend on where you are located. If you need a hand to track one down, get back to me in here. Hope this helps you anyways. Good luck, a FixYa rating for this info will help my profile. Cheers

Trouble getting a picture with a source selector

The input on your television monitor must be set to view the composite with the S video cable. You will not be able to view the component video unless you also have component video outputs going from the input selector to the television. After you have done that, you will also have to change your television input from "video 2" to whatever input you used for the component video hookup.
