US power supply in a PAL Intellivision console?

[+grips03]

Can one install US power supply in a PAL Intellivision console?

 

I assume you have to swap the transformer, however the power supply PCB looks the same. Can someone confirm?

I'd like to know the opposite.

 

I have a PAL Intellivision with 220volts and live in Thailand. I'd like to be able to use the NTSC Intellivision with the 220 volts power supply.

I don't see why you couldn't has long as they both put out the same voltage on secondary it shouldn't matter what voltage is on the primary . My guess is the only difference is the ratio of transformer .

Yes, power supply board is the same. You would just swap the transformer and power cord. The transformer supplies 18.5VAC with 9.25VAC centre tap on the secondary side.

Yellow Lead to Blue Lead - 18 VAC

Green/Yellow lead to any Green - 9.25 VAC

Green Lead to Green Lead - 18.5 VAC

 

The power supply does the rectification to DC and regulation for the 12V DC and 5V DC rails.

 

Once you've swapped the transformer, good idea to check the voltages at the 5 pin ribbon connector before hooking up the motherboard, especially the unregulated DC line.
