[gwarne]

When I plug my Mark III into my cabinet, not sound comes out. What vould be the problem, all the tubes light up.

Fuse.

 

[gwarne]

I checked that and it looks fine.

 

[treedroppings]

there are fuses inside of it aren't there?

I just replaced a 1/2amp fuse in my sovtek head now it works

 

[gwarne]

where inside of them are they?

 

[Boogiebabies]

No fuses inside.

Try a new speaker cable and check the V1 preamp tube. If it's bad your amp will make no sound. I have seen a few just blow up.

 

[gwarne]

what kind of fuses do these amps take?

 

[Boogiebabies]

3 amp SLO-BLO.

I will double check when I get home.

But gwarne said all the tubes lights up, won't a blow fuse don't light anything up?

Check speaker cable and / or try another speaker cabinet.

 

[gwarne]

the cab works with all my other amps, so does the cable, also its the only cab i have.

 

[gwarne]

Alright, I replaced the fuse and still nothing.

 

[Boogiebabies]

Effects return jack. Run a cable from the effects send to the return.
See what happens.

 

[gwarne]

Ive already done that, and nothing. Is guitar center certified to repair boogies? I have no idea where else to take it as I believe there are no techs around here.

 

[Boogiebabies]

Guitar Center is not certified to wipe their own behinds.

Try replacing the V1.
