John,
Those two capacitors would cause you to have trouble getting a signal
through the bandpass on 80 and on 40 meters.
Yes, 56pf is labeled 560 and 560pf is labeled 561 - 82pf is labeled 820
while 820pf is labeled 821.
Since you installed the incorrect capacitors in C12 and C4, the further part
of the mystery must be 'where are the 560pf and 820pf capacitors
installed?' - these may cause further trouble unless located and changed to
the correct values. The parts list can be a valuable guide in checking
where each value capacitor should be located.
