Hi guys,

last night my 2rd Tourmaster 4100 in 4 months died. Walked onstage for the 3rd set and nothing. Absolutely no power. We swapped cables etc. to no avail. Lukey I had a friend with an old crate head I could use as backup (sounded surprisingly good lol). I LOVE the amp but I can't have this happening while gigging as a common occurance.

But this is getting scary. Any idea what could be wrong with this one? The other one I returned so I never found out what the problem was. Help!!
 
ok I found it to be a blown fuse. But, everytime I put a new one in, as soon as I hit the power it blows the fuse IMMEDIATELY.

Any clue to what this problem is? I have a gig is two weeks and need my amp :cry:
 
You most likely have a bad power tube(s), that'll blow fuses. I recommend, especially since your gigging you carry an extra set of tubes. Get two sets of Groove Tubes of the same number rating and set the amp's bias to one set and then the next time the fuse blows, and happens when a second fuse is tried, change your power tubes, install a new fuse and it should be fine.

Gigging with out a back up amp, strings, tubes, cables, etc. is just asking for trouble. Even $50,000 Dumbles break down, matter of fact Bruce Egnater got the call to repair SRV's Dumble when it died before a gig in Detroit years ago. Also factor into this that the average quality of tubes has gone down hill in the last two years and all of the amp manufactures are fighting this problem.

An Egnater Tourmaster 4100 is my latest amp that I have added to my collection. I have been using it and I have had no problems. Yes a bad output tube can cause the fuse to blow. I am lucky in that over 40 years of playing gigs I have only twice had anp amp go out. About two years ago I was playing a gig and my Traynor YCV-40 was distorted and shutting down. It turned out that one of the Electro Harmonics 6L6 power tubes had overheated or shorted. I took the output out of my pedal board and plugged it into the P. A. mixer to finish the gig. On a major tour I would bring an extra amp and extras of everything I might need. I don't think The Egnater Tourmaster amps are problematic, it just happens to be a fluke.

Same exact thing happened to our guitarist with his 4100. It just died out of nowhere. put another fuse and it would blow. Then we put tubes from our other 4100 and still nothing, its gotta go back to be fixed.
:aww:
 
ok I will check the tubes first. I would replace them, but I know of the dangers inside amps. It looks like in the 4100 the section where the tubes are is separate from the rest of the components. Is it safe to get in and cxhange the tubes? I don't want to touch anything that kills me!
 
The whole point of the fuse is to keep damage form happening to the amp when a tube goes. Blowing that fuse means you have a bad tube ... change it! Just grab a hold of those suckers and pull 'em out!!!
 
ok I'll replace them and see if that fixes it. I am just back to tube amps after coming out of my "have a family bedroom Line 6 stuff retirement" so I am a little rusty on my amp stuff.

Thanks guys!
 
The manual should have some tips. Re-biasing may be necesary.
 
My manual says I need to use a 5ASB 100/120V fuse. I have called everywhere and no one carries these. Most don't even know what I am talking about. Is there abother fuse type I can use in it's place?
Sorry about these simple questions but I have a gig saturday :(

Go to Radio Shack, and they should have a 5-amp Slow-blo 100V fuse. I have gotten my fuses also at Menards.

One of those two places, and you should be good to go.
