Amp has been running cooler for a while, then got really hot now even after running it for a few hours it doesn't even get luke warm, I've read somewhere it could be capacitors drying out could this be true ?
Audio output section circuit draws enormous current at idle stage. Contact any service electrician to detect the fault and get it repaired. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. Surf the site with patience. Pull up older posts.

Hi Ingemar... sorry for the delay getting back to you. It sounds like you may have a problem with transformer connections, or maybe orientation of a bridge rectifier. Check all connections in the power supply with particular attention to these. Check also that th3e caps are fitted the correct way around. Look also for hairline fractures in the PCB about the power supply. I am trying to find a circuit for your model at the mo. Not having much luck...do you have one you can link me to or upload to FixYa? Would get me on the same page as you to really get into the problem.
regards
Graeme

Hi There WLAW,
I am in Auckland NZ and do repair work for a high quality Amplifier chain so I could have a look at yours for you....
Being Local in Auckland it will save you sending it away off shore to Australia.

if it is conertable to 120v there will be a tap on the transformer input for that

You will need to use the pre-outs on the receiver to hook up your amplifier. I am trying to verify if that model even has pre-outs for the front channels, many do. You will be able to tell quicker than I can by just looking for outputs labeled pre-out for the front channels. Just use the cables you have to attach the Krell amp to those pre-outs and you will be good to go. Let me know if you are unable to locate them... the receiver may not be designed to do that..
