Does Akai Mod Work For Static Problem?

Anyone have success in eliminating the static/crackling problem in
Akai/Roberts decks by using the Akai mod? I know there is a ton of
archive info regarding this issue, and one theory is to add 1 uF cap
in parallel to the sensing poles by the recording head.
I own a Roberts 808D that crackles in the right channel on most tapes
after it auto changes tracks. When the tape is first inserted and
tracks are manually changed the problem is not apparent. Only when the
player auto changes does the static appear.
I also read that the problem could be attributed to a loose ground
wire connected to the screw that holds the head in place. By
tightening the screw the ground wire will then make proper contact and
eliminate the static.
Do either of these procedures really correct the problem? I'd use this
Roberts deck alot more if I could eliminate the crackling! BTW....this
deck has a cool after mod, the previous owner had a pause mode added
on using a toggle switch and an extra light that comes on when
engaged! I would really like to get this deck to play the way it
should. The sound is very nice otherwise.
