Once rectified, smoothed and regulated the Yamaha PA-20 can deliver up to 0.52A
continuously into both 15V rails.
You should fit both fuses and both should be anti-surge types and rated at either 1A or 1.25A.
Yamaha PA-30
This is essentially a bigger version of the PA-20 as detailed above which supplies 18V-0-18V

continuously. You should again fit both fuses and both should be 2A anti-surge types.
