Blowing Fuses. Dennis Had Inspire 300B SET

I was disappointed this evening, as I was listening and all of a sudden I blew a fuse, and I don’t have a manual. I don’t know if the fuse is a fast blowing fuse, or a slow blowing fuse. The one in there is a two amp, and the fuse itself is a zigzag not a straight fuse I replaced it. And it blew again and I saw the rectifier tube had a reaction when I turned it back on. Does anyone have any experience and can anyone give me some advice thank you.

Turn on the amp without the tubes installed. If the fuse blows send the amp in for repair. If not, then there's a 99% chance it's a bad tube.

A Dim Bulb Tester can save you some fuses.

I found a gut-shot of a recent Inspire 300B amp (Steve Huff).

The rectifier is lower/left.

@carlsbad2 I'm not certain how you arrived at this:

Your opinion is noted and considered overly optiomistic at best.  You are a manufacturer and have an overly proud opinion of manufacturers IMHO. 

My prior comment is based on experience. I started my career in 1974 servicing consumer electronics and that is how I put myself through engineering school.

You don't put a fuse of a higher rating in any kind of equipment, especially if that equipment is consistently blowing fuses.

Bad Things tend to happen.

I have no idea how you might have arrived at the 'overly proud opinion' thing. To me the comment makes no sense, so I suspect its not accurate 😉
