Anybody has information or schematic for this power board SB-12 power module? The unit is rated 120VAC but was accidentally plugged to 220VAC.
Transformer T1 has a burnt primary winding, shorted Zener diode D6 (don't know the value) and damage capacitor C4(6,800uF/16V).

C16,D3,D4 was also damaged on MC-60 board.

Attached is the image of the board.

Any information is a great help.

What is an SB12? I'm getting many matches on different devices; 12V power supply, treadmill power board, submersible rechargeable pump, etc.

Quite honestly I would just buy the one on ebay for $55. Because IF you can find replacement parts, especially the transformer, you'll spend more than that in time and money fixing it. Just my opinion.

 

Maybe I'll just buy a new treadmill then.

 

The transformer is probably an OEM type, custom made for that vendor's power supply. Odds on finding such a transformer are very low. Only real possibility is to find someone else with the same board with a working transformer that wants to give it away or sell it..
