Post Sansui AU-317 restoration project - 56k warning

I am going to try and document the refurbishing of this wonderfull piece of amp. This is still a masterpiece from when Sansui was Sansui!!! Produced between about 1973 and 1975 (my birth year)

First error was resolved by finding blown fuse... but I believe after all these years all fuses are due for replacement.

Most of the fuses have rateings of xA at 125V, fuses available to me are normaly 250V, do I just divide the current of the 125V units by two if I want to use 250V fuses or would I be better off ordering some 125V ones?

What is the verdict on those large Elna caps (30+ years old), stay or go?

I think they samller elco's are probably due for a replacement.

It was quite a job getting the crust of thick old dust out of there and I will go get some compressed air when I can drive again, to do a better job.

P.S. I would love the service manual for this model.. I have most of the manuals for the models on either side, but they do differ more than you'd think.

Now for some pictures

It can litteraly reproduce signals from 0Hz to 200kHz.
I have heard this unit before... it is proabaly everybit as good as HRII, will run them side by side when I'm done, as a test... I would not be surprised if it wins though... it had an awesome musicality to it.
