I HAVE SOUND !! Took the advice and removed the cable and checked input to ground and found I had a circuit from metal braid to input cord. When I soldered the metal braid to the RCA Jack and to my jumper at the cartridge end, I soldered direct to braid which "as warned" burned right thru to the insulation to the inner cord shorting the braid to the inner input cord! I re-wired by using Jay's direction of pulling diamond braid back off inner insulation twisting it and used a pair of surgical hemostats to hold and use as heat sink to keep heat from inner insulation while soldering.
Re-installed being careful that all clips to the cartridge were insulated. Great sound came from the P132D cartridge!! 
One other item.... does it matter which of the flip needles you use on the P132D ??? Now that the sound works it's on to the next problem with this 1438 Juke... the coin and selection issues. This juke is playing one record after the next without stopping unless I cut it off using the switch next to the the record load switch on the control box.
Thanks to all you guys for your very accurate advice... Ron, Jay, Bob, Don, Wes, and James!!! You all have a Happy and Prosperous New Year and keep on Juk'in!!
