power surge blew fuse in stereo

what makes you think it was a power surge?

PSU problem. Is it transformer or smpsu?

Probably have a failure in either the power supply or the power amplifier. It could be a big deal.

It may not have had anything to do with a surge. Obviously one or more components are shorted, it shouldn't be too hard for an experienced tech to fix but if you have some experience troubleshooting electronics, a multimeter and soldering equipment, there's nothing you can do that won't make it worse and more costly to have repaired.

LOL! Is this a typo or are you saying if he does anything it will make it more expensive to repair. Thats proably true, but funny.

Yes, if he does anything while not knowing what he's doing, it's very likely to do nothing but damage it further. I've seen it more times than I can count.

I thought it was funny because you said if he had expirence troubleshooting he could only make it worse.

The most common cause is a failure in the output stage. The failure is usually the power output devices, their respective drivers, and sometimes their support components.

Is this the line power input fuse ? In what way does it blow - with a soft blue flash or violently with a bright white flash and total vapourisation of the fuse wire ( inside of glass blackened ) ?

Are you replacing with the correct fuse type - almost certainly " T " rated ?

I see many HiFi's with a blown fuse after some kind of power surge - often due to power interuptions when there's storms about, and I actually find it quite rare on modern equipment for there to be any issue other than the fuse. That's not to say, of course, that surges are nothing to do with your problem, and it has plain and simple just gone wrong.
