Cyrus PSX (original for Cyrus 2) Recap. - Which caps ?

[einsteinagogo]

Okay, so after this thread and warning shot..

https://www.diyaudio.com/forums/sol...-psx-blows-fuse-mains-plug-2.html#post6301599

time to replace the 4 x 15,000 uF 63 volts in the PSX.

Looks a simple job, just 4 caps to desolder and resolder.

So which replacement caps are suitable based on uF, voltage and sizing.

I just quickly Googled, 15,000 uF, 63 volts - I think that's what they are...

and found these on Mouser...

LKG1J153MKNF Nichicon | Mouser United Kingdom

Are these any good ?

and recommendations ?

I am sure you will get plenty of advice on this subject of capacitor replacement .
Looking at mine -PSX-R they employ 50 Volts Cyrus patented slit foil capacitors of 7000uF, I think this is a case of "badge engineering " as I don't think Cyrus made their own capacitors but they were made in the UK

Think it was BHC Aerovox who made the slit foils, now owned and badged as Kemet they still make some but only 10000uF - the ALC10S series.

Slit foils last longer than standard parts, however if replacing any good brand would do, like the Nichicons you linked. Even if you did drop to 10000uF parts you likely wouldn't notice much difference.

I recaped most of the small ones, but left the power capacitors alone on my Cyrus 2. They seem to work OK as the amp plays for some time after switching off.

I used Nichicon KG for the main power caps in a recent recap of a Musical Fidelity E1. The rest were Elna Silmic II, all from Mouser.

Sounds excellent!
