samuelcroberts Posted September 24 Share Posted September 24 Hi All, I was going to replace the output jack on my Moollon P-Classic due to an intermittent issue (wear and tear), but noticed there was only one wire connection to the socket with no ground directly from the jack socket itself (see photo). The bass has no ground issues at all, so I'm presuming that the ground is supplied by the metal tape stuck to the underside of the pickguard or something, which you can see in the pic. Can someone who knows more than me confirm that I don't need to add an extra ground connection when replacing the socket? Presuming it's fine, as this is how it was wired direct from Moollon, but I am an extremely amateur electronics person who just happens to be decent at soldering... Many thanks in advance!

PaulThePlug Posted September 24 Share Posted September 24 @samuelcroberts Yep... But, Ground Connection via the Plate Foil... then usually the pots 'n jack are mounted with Serrated Star Washers... that eat thru the foil. So might explain the intermitancy. I'd rewire but include the pot earth links or TCW Busbar... Jack? Go for a Pure Tone Multi Contact... Clunk! they feel the nuts, game changer! 4 Quote Link to comment Share on other sites More sharing options...
samuelcroberts Posted September 24 Author Share Posted September 24 @PaulThePlug Cheers mate - that's really helpful! Is there any danger of creating a ground loop if I add an extra earth link to one of the pots? Presuming not, as it's a completely passive circuit, but just curious.

PaulThePlug Posted September 24 Share Posted September 24 Nope.. If it is still open i'd just run a bit of stretched tin copper wire soldered across the pot cases to the jack socket... leave a little S in the wire where it joins the next, just in case a pot or the jack works loose. 'Prolly no need for a re-wire... 2 Quote Link to comment Share on other sites More sharing options...

samuelcroberts Posted September 25 Author Share Posted September 25 @PaulThePlug Just to say thanks again - went to replace the jack this morning and noticed the serrated washer had started to eat through the foil, which was definitely causing the intermittent issue. Added the extra ground without changing the socket and that fixed the issue. Who knew! Thanks for your help! 1 Quote Link to comment Share on other sites More sharing options...
PaulThePlug Posted October 2 Share Posted October 2 ^ Whatever the issue, big, small... Someone has likely been there or might know - and thats 'Basschat' 1 Quote Link to comment Share on other sites More sharing options...
