Philco 84 Bakelite caps wrong data ?

Finishing an 84 as a Christmas gift for a friend, aside from an open
antenna coil (primary, minimal challenge to fix),
I found out a miswiring problem on the audio
section. There's a Bakelite cap with code 7762-B. I restuffed it
as per the service bulletin available on Philcoradio.com but doing
so makes the 42's grid go to ground through the coupling cap
instead of going to the detector's plate (through a 10K).

Wiring seems originals as all wires and resistors fit perfectly and there is
no way I can swap connections...there is only the section going from the
42's
grid to the detector's, the other cap's section is fine...

Now I have two options: pretend the data from the service bulletin is wrong,
(which I doubt it is as all Bakelite caps from the service bulltein are
using
pins 1-3 and 2-3, but hey, what do I know...) or...
a previous tech miswired the Bakelite cap (again, wiring is neatly placed
and I would need to use a jumper to make everything go where it belongs
if I swap lugs).

Can someone shed light on this ?

I fixed it no big deal (aside from the coil, it's already really past my
bedtime),
but I'd like to know what's wrong here...
