NAD 3155

I’ve been looking at replacing the electrolytic capacitors in my beloved 3155. The service manual has a value of 50V 0.6uF. Having looked for supply I can only seem to find 1uF capacitors. What would be the outcome if I were to fit these?

They will be just fine.

You can very well use 1uF cap.
It is just as good. Or even better.
But we should not use caps with lower value, like 0.47u.
Be sure the voltage rating is 50V or more.

Thanks for your responses gentlemen.

C617 & C667 are 0.68uF 50V. They appear to be in a tone control circuit so the value may be important.

Probably better to use 680nF polyester capacitors there if there is room.

I had a look at the schematic for the first time today. I see there are more Electrolytic capacitors than in the parts list, unless I'm missing a page- which, I don't think I am.
