Depending on what we're talking about here, most devices will tolerate +/-15%, or in your case, 7.65v to 10.35v. A 6V power supply will only give the device 66% of the power it's rated for (not enough).
Even if you could find an adapter that would fall within the 15% tolerance, it's not a good idea to try it. A multi-voltage adapter can usually be purchased for cheap at your local RadioShack or if you're feeling lucky, you might be able to find one at any place that recycles electronics (Goodwill or any local recyclers).
No, the mA rating of adapters is the maximum amount of load that can be drawn from the adapter. 1 amp is equal to 1000 mA. By replacing a 800 mA adapter instead of using a 1000 mA adapter is limiting the connected devices load by 200 mA. If the connected device draws 800 mA's or less then the adapter will work.
No. Your portable radio needs 800mA to operate. Your adapter can only produce 400mA. If you make the connection the adapter will rapidly heat up and probably burn out.
Yes a device will only draw the amount of current it needs if the voltage is the same it will draw the same amount of current. Since your going to a power suply with a larger max current you should be fine..just don't step up the voltage.
Yes you can, as the pedal draws only 35 mA, which is less than the maximum current the supply is capable of delivering.

No, the adapter's power output has to be equal to or greater that the current draw of the device.
No, of course not. The 6v adapter only produces 6v, while the load expects 9v.
Yes, a 9v 1100mA power adapter work with your 9v 500mA device. The mA number is the maximum amount of amperage that the adapter will produce without overloading itself. At 500 mA the adapter will only be working at half load.
A device which requires 1000mA at 9 volts in order to operate will not work from an output of 500mA. This output is only half the power requirement of the device.
Yes, the manufacturer specifies what the working voltage of a device will be and that voltage has to be adhered to.
yes, if the other adapter is a va
No. The adaptor will overheat.
Yes, the rating of the adapter is the maximum amount of current allowed to be drawn from it. The adapter you state has a maximum of 1000 mA or 1 amp. If the device draws 700 mA's you will have 300 mA's of spare capacity.
No, the voltage is wrong. The device needs an adapter that only produces 5 volts. The device that you need may state on it 2500 mA instead of 2.4 amps
You can use any 9v adapter as long as the output amperage is rated higher than the amperage rating of your appliance so yes a 600ma adapter can be used to power a 500ma or 400ma appliance
No. You need to use the exact battery charger for the battery specified by the manufacturer, in order to achieve the correct charge cutoff point. In particular NiCad and similar batteries detect full charge by detecting the knee point in voltage per unit time given a specific charge current. Using the wrong charger could result in overcharge which will damage the battery.
No. There is a 50/50 chance it will work. Check the polarity on the label. Some adapters have the positive on the outside sleeve of the plug, others use the center portion. The device may be labeled, or use Google to locate the correct adapter for it. If you use a plug with the wrong polarity it might fry your device.
