Krell KAV-3001 left-channel cut-out

While moving this amp with the power on I noticed that the left speaker cable connection was loose - after tightening the connection the left-channel of the amp went dead! For every input there is no left channel output. Diagnosed the problem by switching the speaker outputs and the right channel works fine. It's definately a problem with the left output.

I presume this is caused by a blown tube inside the amp, but as I have practically no experience with high-end amps can anybody else offer diagnosis/assistance with fixing this?

My main concern is where I can have this fixed and the cost. Does the entire unit need to be shipped to manufacturer or can a shop open this up to replace a tube?

Any help is appreciated, thanks.

I've called the retailer of the unit, and besides clarifying for me that there are no tubes in Krells (thanks Stevecham) the opinion is that it could be a blown fuse. I didn't realize that each channel had a fuse, otherwise I may have suspected that earlier on (I figured one fuse for the unit, so if blown I wouldn't have gotten any signal).

I'm gonna try the configuration on the remote first. Thanks for the advice Jimjenjr.

If that doesn't do it then I probably need a fuse.
As far as I know the fuses are inside the unit, and I'm not about to open it up. Back to the retailer for repair I suppose.
