Rolling up or down shows that you are changing the frequency, but if you can't get it to slow down to zero beat with point J grounded, there is something wrong in the oscillator (or maybe control) circuit. The caps you replaced would not be critical unless completely dead or very wrong values. Look for trouble with the cap values in the oscillator and control circuits.
C112, C118, C114, C111, C108. Due to C108, there should be no 3.58 MHz energy whatsoever at point J, only the low frequency beat note.
