I'm looking for a pair of 270uF to 330uF film/foil capacitors (preferably polypropylene) for a parafeed amp build. Voltage rating should be 250V DC or better. I would also consider paralleling a couple of smaller caps (70-150uF) to make up the final capacity.
Thanks for looking!

On eBay Germany there's an offer of 200x2,2uF MKT for 15€+postage. I know it is not the format you wanted but the price is excellent.

E: not my offer, I don't know the seller either

Maybe can take a look at these. Highest value in the shop is 200uf, I think.
Just found this amazing item on AliExpress. Check it out!

They surely look great but I'm not a fan of Ali. I don't know what rating you actually need but the text says it's 250V DC, which means it's AC rating is lower. And the photo says 250V AC. I guess you will find out eventually.
I think the caps will see something like 60-80V DC bias with - worst case - about twice that in AC peak voltage on top, so 250V DC should do the trick.
Before I consider commercial offerings, I was hoping that someone might have a pair of coke can sized caps stashed away somewhere...

I've been eyeing the DC Link caps for a while now. I guess if they're not satisfying directly in the signal path, they might still be useful in a PSU. Maybe I'll give them a try if nothing else turns up 🙂
There is also a deal on Ebay for 47 uF , "Audiophiler" 250V MKP capacitors. 5 in parallel would get you the capacitance you need. No doubt they are metallized PP, but you take what you can get....
My opinion is,if you looking for something cheap than Panasonic or Vishay DC link are OK,if you want something better than Clarity TC and Mundorf Tubecap are one of the best😉
But off course becose you need only 250V dc typ you can choose also some other PP caps like standard Jantzen,Mundorf,Clarity SA and ESA and so on.......

He doesn't need to put a 2nd mortgage on his home to buy the caps he needs. I'm wondering why the cap value ne needs is so high in the first place...
A combination of electrolytic and film cap may be at least as suitable and a lot less expensive.

Mouser has some Kemet 47uF polypropylene caps for automotive duty. They actually have a 250VAC rating. They ain't cheap, but they're not audiophool expensive, either. The caps have 4 leads, so it's a specialty part that needs a new footprint in whatever PCB layout software is used.
I have Jantzen Audio Cross Cap 270,00 µF +/- 5% 400 VDC MKP Size: dia.62 x 112 mm - price 65€/pcs
yes they are expensive. but there is some critical places where they must be used. I planned to build solid state preamp and its power suply is nothing like ordinay solid state suply. but.. so much project and so little time 😢
