Re: Blowing Radio Fuse help
It's quite normal for an old glass type fuse that's been in service for many years to just fail due to old age, so nothing to worry about unless it keeps happening. Just make sure that you replace the fuse with the correct type and rating.
No, it's not a good idea to remove an output type valve permanently. It'll take too much load off the power supply and cause all the voltages in the set to increase above their safe values.
You need to investigate and cure the bad connection crackling, as this can lead to possible arcing and eventual tracking with possibly burnt components, or worse. It could be dirty or oxidised valve base pin and socket connections, or it could be a bad circuit connection or dry joint, it could even be a cracked resistor. Close inspection should find the issue.
