Component Question - Electrolytics in Power Supply

[Geaney]

I'm currently working on an FM tuner and the main PSU electrolytic needs replacing. I've tried re-forming but at least one section of the cap remains leaky and it runs too hot. It is a four-section electrolytic - 2 x 40uF, 2 x 20uF all 350V. Because it uses circuit boards, the chassis is not deep so there is no room for putting replacement caps underneath. I can't really stuff the existing can as I can't fit four replacement caps into it.

I went hunting and all I could find as a candidate replacement is a 4 x 40uF cap 350V. My question is would I get away with the increased capacitance for the two sections that should be 20uF? I've attached a picture of the power supply and one or two of the tuner itself. The item marked C32 on the drawing is the cap in question. From left to right they are the 2 x 40uF then the 2 x 20uF.

All advice gratefully received.

Cheers, John

Can't see that posing a problem, and it might actually improve it.
I expect they used 2 x 40 and 2 x 20 because it was cheaper and/or that was all they could get in the can.
Go for it.

The value of the resevior capacitor won't be increased so I would agree.

Thanks Guys,

Much appreciated. I'll post an update once the cap arrives and is installed.

Cheers,

Replaced that quad electrolytic in the Dynatuner - and two valves that were very weak - sounds nice now. Gave it a general polish up as well.

Cheers, John

nice looking amp john.
i will be interested to see how that valve decoder performs.
