Default Mc Crypt PA-5000 fuse ratings

Hi rat!

I was given a Mc Crypt PA-5000 amplifyer with the two internal fuses
missing. Fast 2 A fuses were blown by power up only, probably by
charging the capacitors. Fast 7 A worked, but are probably overrated.
The AC current measured with a multimeter goes up to 3.7 A peak during
strong deep basses. I read the unit is prone to dying (domed or leaking
capacitors) under high load so maybe 4 A fuses are still too high and a
more protective slow 3 A fuses may be sensible. What do you think? Which
rating are the original fuses?

Thanks, Bernhard
