KRELL KCT preamp. FUSE BLOWN

Ideally the fuse would protect the unit in certain scenarios. You may wish to check if there are any internal fuses. It is indeed a problem of a sort one could only guess at until properly diagnosed.

Be your unit under warranty or not I would contact Krell for their best direction. They may have approved list of service centers in your area, or suggest a return to them. Good luck.

I also have a KCT. Never even hinted at any issue. I would try to isolate the problem. Perhaps disconnect everything connected to the pre, unplug the unit, replace the fuse, plug it back in, then turn it on. The KCT goes thru a small boot up cycle prior to going into the "on" mode. If it goes thru the cycle and stays on without the fuse blowing then the issue would be somewhere else.
If it still doesn't work contact Steve Lakrone at "The Service Dept". He used to work for Krell and is the The Man.
Hope this helpe, John

Yes also KCT here. And ditto above advice.
