You know first of all you must b sure of what electricty voltage iis supplied at your home.. well im from maurotius and here we are supplied about 230v,therefore it is recommended for ur to tune our power supply at 230v.. But sometimes there is a high frequency of voltage which passes through our cable and this may cause prob.. the best solution is to try to change your power supply..this might b the solution for your problem. dont worry as its not expensive.. if still you are getting problems,then try to serach for a pc technician,if you do not know anything about power supplys,then never try to play with it.. it may cause damage to other parts of your pc.. mail me at [email protected] if you still have another problems.. take me as your friend..

You must first determine if it is 30amp of 50amp service. If it is 30amp you will need a 30amp RV receptacle. 30amp receptacles are 110vac. DO NOT WIRE THE PLUG FOR 220! It will damage the converter and possibly more. If it is 50amp the it will be 220vac. Most power cords are 25' for RV's. When you go beyond that distance then you will experience voltage drop which could present problems with breakers overloading and tripping. With that being said, your local RV parts department will sell extension cords for RV's. To determine what amperage your trailer is, there is usually a decal above the plug port that will identify. The main breaker will also give you a clue as to the amp rating. If you have the power cord, look at the male plug end and if there are three brass terminals it will be 30 amp, if there are four terminals it will be 50 amp.
It's probably belongs to a system. However you can use a 12 volt power supply to work it, if you are any good at electronics. It will probably use a 12 DC supply. There might be two presets for the speeds one 45 one 33, these will need to be adjusted with any other power supply. You might find them on the underside of the turntable. A look inside (take off the bottom) will give you clues to the kind of power supply it uses. For example you might need to add a electrolytic capacitor to smooth the supply if the power supply you use isn't already smoothed.
Power Supply 100–240VAC, 50–60Hz
Power Consumption 232W max.
Its mean its a switching supply that can support as low as 100 and more as 240VAC
If there is a problem with supply and you want to attach a fix one then
Check the MAINS at your area. If it is 110VAC then get it and if its
220VAC then use the supply for this kind of support
If your main power is 220Vac and it is set in 115Vac. It could be you actually fried your power supply.
Here is the reason, in common power supply after the rectifier diode when it is set in 115Vac, its circuit acts as a voltage doubler, its mean in its downsteams it actually uses around 220Vdc. And when you uses it in 220Vac it will connect directly as a rectifier.
When you set it in 115Vac and plug in 220Vac. In its downstream it could be in 440Vdc, then its an overvoltage everything that can't compensate will be damaged.
The battery select determines whether you're using a NiCd or Alkaline battery, I believe the "adjust" is used to put the radio into service mode. If there's not an "auxiliary power input" you can hook up the bench supply to, check the battery output for the voltages and polarities, and hook up your supply accordingly.
