Where to get high voltage/capacitance polyprop caps for PSU's?

    It's been decades since I fiddled around with tube amp building.
    In those days polyprop caps in a PSU was unheard of and beyond anyone's imagination unless you wanted to use a million of them in paralell.
    In today's day and age high voltage/capacitance polyprop caps are common and I've managed to find 47uF/630 volt Solen caps at thetubestore.com.
    But,-are there other places (preferably in Europe or the UK) where these can be found?

    Mouser: has 15uF/600V polyprop caps.
    Digikey: Either the site doesn't work correctly or there are no axial polyprop high voltage/capacitance items.
    RS and Farnell: Lots of polyprop motor run caps @ 440 volts. -Is this AC or DC voltage? -As far as I can see no axials with the required capacitance/voltage.
    falconacoustics.co.uk has Solen caps up to 100uF and 400 volts.
    https://www.tubesandmore.com/ has Solen Fast caps, 47uF/630 volts.
    Seems like the largest shops don't have them while the smaller and more specialized shops do.

    Here are all the spec sheets I've collected for DC Link capacitors, if you need over 40 uF. Solen has a series of film caps 47 uF and below at way better prices than DC Link caps. DC links which seem to start at $15 and go into the hundreds $ per unit for anything over 47 uF. WIMA and others under 47 uF are reasonable, but when you get above 47 uF Mr. DC link walks in and prices jump. There may be more DC link types than these, but I recently surveyed DC link caps myself so had this folder handy!

    Adding Solen, it appears in their 400v line they do go over 47 uF, Ill have to look at these too.

    The Dayton capacitors at Parts Express are re-branded Solen capacitors, another alternative.

    Hello,
    After Brexit i did not order anything anymore in the UK. I only hear horror stories about getting things from the UK, time-consuming and more expensive.
    Unless you wanna buy something that has been made there it would seem illogical to buy something over there that has been imported from EU and then '' move '' it back again.
    Greetings, Eduard
    P.s This is a company where i have bought things several times.

    Hello,
    Usually i would buy just things there that you cannot find in EU countries. Even if ''catalogue prices '' would be competitive in the end you will pay more because they decided to leave EU.
    I wrote the original poster a small message stating that because the cap is plastic and not an electrolytic one it does not have to be automatically better.
    There are several people who do prefer the caps filled with oil . Nowadays most caps contain a kind of resin instead of a (biodegradable) oil. Some decades ago oil was usually a PCB containing type.
    Siemens/Epcos MKV are very nice but obsolete now. Not old enough to contain pcb.
    ASC/Shizuki still makes them and they can be found at affordable prices at non-audiophile shops.
    Russian K75-17 are very nice but big. I use them because i needed the extra voltage rating.
    General Electric Dielektrol are nice too.
    Greetings, eduard
