Help/Major Problem


I have a Aleph-3 amp and a Rogue 99 pre with phono.
I played the system all last eve. with no problems.
Tonight I fired it up and nothing!
All seems fine except no sound.Only a muted signal(music) when I turn the pre way up.I can see the line stage tubes through the cover of the 99 and they are lit up.This problem is with phono,CD and tuner.I have checked all I.C.'s and P.C.'s All check out fine.
What the hell could be the problem?

Yeah Kelly,I always knew there was something else lurking behind that clean lawyer image! :~)
I have checked all there is to check without opening up the Rogue to check the tubes.
One correction from my previous post.I get a signal with the pre turned all the way down.Very low,muted music that increases slightly when I turn the pre up.All cables and I.C.'s are fine.
Kelly-I'm going to need more than "a couple" ludes before this night is over!
If it were a bad fuse I would have no tube glow or amp on indicator light,would I ?? I don't think either the Rogue or Pass has fuses anyway.The Pass has thermal overload protection but no fuse as far as I know.
My hunch is it may be a poorly seated or bad tube in the pre.(Its too late in the eve. to rip the pre apart)But with both channels affected this seems unlikely.
Anyone else have a clue?
UPDATE..... I removed the cover of the 99 pre.I took out the 250W fuse.Inside the fuse is a thick copper colored strip with solder on the end with two thin wires coming out of the solder.The strip only goes half way across inside the fuse.The 2 small wires do not continue to connect to the other end of the fuse.They are just hanging there.I put in a new 250W fuse I had for my Dynaco ST-70.This fuse says on it 3 amp slow blow.The one I removed only says 250W.The strip inside the new one is very thin and silver colored and is connected to both sides of the fuse.Anyway,I have music now.It fired right up!
Now my next concern...Is my rig going to blow up and leave a crater where my house once stood??
Thank you to everyone for sharing in my crisis.
I will get in touch with Mark O'Brien and see what he says about what fuse to use.
Kelly,yes,I mispoke when I commented the Rogue has no fuses.Actually it has 1 and possibly 2 in the power supply also.Sorry,must have been those ludes!
FINAL UPDATE- I heard back from Mark.He said the problem was a too low amp fuse in the 99.He said until last year they were putting in too low amp fuses of 1/2amp or 3/4amp...he said to use a 1 1/2 or 1 3/4 amp fuse.I will get one asap.Again,thank you all for all the help and support in my time of emergency! :)As this topic drifted off a bit into the discussion of ludes and lewds please continue this most important topic(s)!!
