Is this thing a capacitor?

[veg-o-matic]

Greetings, all:
This is my first post in this forum, though I see some familiar names here

Here's my problem. I have an Airline radio model GEN1538A that's not fancy or expensive, but I like the way it looks. It has some hum, which I believe I can fix by replacing the filter (electrolytic? I forget the term) cap.
Oh, it's a solid state radio, so I hope it's okay to post this here.
Anyhoo, I've replaced these caps a couple of times in the past and it was always obvious which ones needed replacing. I'm not too sure with this one.
The most likely suspect is this wax-covered thing about the size of a roll of Life Savers. It doesn't look like what I was expecting, but I've heard the term "wax-covered caps" so often here that I figured it's what I'm looking for. This is like, a mid-60's model, so I was surprised to find something that seemed so old-fashioned inside.
Okay, this is what's written on the cap in question:
======================
Cosmic Condensor Co. 704
E3264
Red + 150M 150WV
Grn + 50M 150WV
Black Com Negative
=====================
I'm guessing this is some multi-part cap?? Do yall think it's what I should replace to cure the hum? And what should I replace it with? Perhaps a 150M and a 50M cap with the negative leads soldered together?
Or would something like that blow up? Considering my skill level, that's a distinct possibility!
TIA for your help.
