No more test to be done .I find there is a problem on the old pot. .If i test the new pot i can see the problem . The readings are as you said only not 50ohm but 47 ohm .It is a 470k pot
So the old one reads not 500k or 470k . The reading i get is 100.ohm on top scale X10K why is it reading 100ohm ?.
The pot is out ,and a new one in place ,just need to solder the pcb Wednesday ..Talk lWed after its in . If you are about Graham..I have ordered an auto test meter .
