I repair old radios and they are available but you can use two caps. See link. Two separates is cheaper. Also most people prefer those rated for 105C not the more common lower temp vales like 85.

OH,There is one problem with the size ,to long for my application.
Can I use a cap of a higher ,say 100 uf?
There are also a few wax looking caps around the power supply and a few coupling ,I think,caps too.The power supply caps look all the same but the two coupling caps look different.
What would you use in this situation for these?
They are small values,.04 and .02 and there is one .005 all of those are 400 vdc.
Thanks for the help
First, does it work? Does it hum? I'd start with that large filter cap.I'd also stay closer than you proposed in value. I find little problems with the smaller caps but test their value and replace them if you want or they are bad. Read the link below, lots of good info.

Yes,the radio works and has a hum.
I thank you for the attachment,lots of information that will help for sure.
I replaced the mains cord,now the big filter cap.I was wondering if I can go higher with the values? SAY 100 uf in both stages?
Some of the smaller caps have wax that looks melted?
I'll read more on the subject and use my discretion.
I'll make it.
I'd stay close to the value called for in the radio. Good luck, that should rid the hum.
