[Amps] Al-82 Blowing fuses?

[Vic K2VCO]

I understand that slow-blow fuses are intended for motors and similar devices that 
normally take a longish time -- maybe a few seconds -- to come up to speed and draw much 
more current in that periods. They are not intended for electronic devices.

If you find that you can't keep from blowing reasonably-sized fuses on startup, a better 
solution is a soft-start circuit. That also lightens the load on relays, diodes, tube 
filaments, etc.

Yes, I know that some amplifier manufacturers have called for slow-blow fuses.
