Did you assume an electrolytic due to the size?

I've never worked on a B&K 440, but the 350 and 400 in the same series use a .1 mfd 1000v wax paper capacitor for burning out shorts, and that capacitor is always found defective. The electrolytic in those units is a 5 mfd 250v, and it is physically smaller than the wax paper one. The less expensive B&K 420 uses an .01 mfd ceramic and no electrolytic.

Just Radios lists a .1 mfd 1600v Orange Drip for $2.99, a 2K v one for $4.99, a .1 mfd 1000 volt Tubular Axial Met'd Poly Film for $1.49 or a pair of .047 mfd 1600v disc ceramics for $.99 each. Any of the above should work for this very non critical application.

Of course, there still is the minimum order.
