Capacitor advice for a Startrite 275 table saw 240v

[mickthetree]

Hi all
Been a long time since I popped by the forum! Lots of life changes. Glad to see the forum is doing well and lots of new members.

My table saw has been slowly loosing uumph over the last year. I rarely use it to be honest, but need it to work when I do.
From reading round it seems most likely the capacitor.
I've attached an image. I can find 120uf 250v ones on ebay. Is that all I need to match? There are loads of other numbers on there 439/1/90032/090. How important is it to get a perfect match?
Many thanks in advance for any help
Kind regards
Paul

Thats a name from history, Plessey but you want a motor start capacitor at the correct capacitance and voltage which needs to be the same or higher but not lower.

Hi Roy - Many thanks for the prompt reply! I can find 120uf 400v capacitors. Would it be safe to go from 275v to 400v? Or are there limits on increasing the values?

I can find 120uf 400v capacitors.

Much better having a higher voltage rating than getting one rated for a lower voltage. The Capacitance is important and better to replace like for like, ie 120 uF but the voltage is what it is designed to operate at.

Great, thanks again!
