Title: fuse blowing
Post by: lifted on July 02, 2007, 10:43:44 PM

I have a Rivera knucklehead amp and just recently in the last week it has blown two slo-Blo fuses.  Both times I had just turned it on, (I always have it on standby first,) and just as I flip the standby to ON  it blew the fuse.  Anybody know what is causeing this?

^ +1. You have at least one bad power valve.

Aye, sound like the tubes to me.  My Marshall JCM800 blew in the middle of a gig once...  I went through another 2 or 3 fuses before I found out it was the tubes.  I ended up pull two of the tubes out & it worked fine thus confirming my dying tubes as the problem.

Thanks, guys,  I had a few extra fuses to try and watched the tubes as I turned it on, and sure enough a big red flash(almost like a fire) went off in one of my power tubes.  I pulled out that one, and its mate.   Gives me a good excuse to try some better sounding tubes.  I just wish it was biased for 6l6s.  Does anyone want to rcomend the best el34 for cleans, ala much more headroom? and less harsh mids?   thanks for your replies
