Transistor for Sp300

Not familiar with the Roland, but transistors vary even on the same board, and as such, aren't a one-size fits all solution. Did you fry one? Can you read any of the markings on it? If you can narrow down its information, you can easily enough find a substitute.

 

The SP300 will contain 2 transistors, the C4131 and A1746. I have purchased them through Mac Media or eBay before.

 

we can buy this original Roland transistor in low price. our technicians always repair Roland boards, use many this transistor.

Some clients buy spare parts from us, we sent transistors for free.
