   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
