For example,in the F5 amplifier,it is advisable to start with the trimmers at 0 ohms and starting turning them up half a turn each one,until you get to the proper bias and dc offset.
Turning just one pot to the end without turning the other leads you to burn the amplifier

Hello,
What fuse size are you using? I am using a softstart board so they don't need to be slowblow
I am building them as monoblocks with a 500VA and 200.000uF each channel. It has 2x PA150 boards per channel in bridged setup.

Regards,

Making a rough calculation, for a 500VA trafo and 220v mains, would I need a 2,3A fuse?
