KRELL KCT preamp. FUSE BLOWN

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.

Yes, without question best guy to call is Steve Lacrone.
He used to work for Krell and knows everything about fixing Krell products. He also fixes tons of other high end equipment.
He fixed one of my Krell KAS Amps at a good deal.

Here's his site and info.

Thanks for all help..

All good advice. But let me say I have had outstanding service from Krell over the course of the last ten years. I have owned amps, preamps, and a KPSc-25 (did I say it correctly?).
They were fast and reasonable, and explained what was happening whether it was for a warranty repair, or an upgrade, or a cosmetic repair.
