None in the 620. Morzh may have been thinking of the 630 in his initial post in this thread (post #4), which is very similar to the 620 but uses a 10 uF, 50 volt electrolytic between B- and ground, with positive going to chassis ground. Note that he corrected himself in post #7. The 620 (your set) uses a 0.25 uF cap (which is a paper cap, no polarity) from B- to ground.
