Help with Nippon Chemi-con 88D capacitors

[housing]

The attached photo shows a populated regulator PCB (Takashi Kubota's circuit) that I built in the mid 1990s for an unfinished buffer pre-amp DIY project.

Does anybody know anything about the Nippon Chemi-con 88D 5600uf capacitor? I was told that it was a Sprague OEM and the price when I purchased them was terribly high. They have 4 leads, 2 positives and 2 negatives. Due to my ignorance at that time, the leads were soldered through respectively. Should they be soldered as one input positive, one output positive and similarly for the negatives, just like the Jensen 4-pole electrolytic or some Soshin Capacitors?

Thank you in advance for any input or advice!

Still no reply after a year?

They're probably some kind of T-network capacitor where one set of terminals is to be used for the line supply, and the other for the load.

Thanks, Jaycee. I'll go and have a look at the link.

Hello. I have same, but only named SPRAGUE. Did you find there is possible order spare? I can’t find part number for these capacitors. 40VDC only is everywhere.
