tommorichards Posted February 16, 2013 Share Posted February 16, 2013 It measure 5.5 ohms. Not kilo ohms, but ohms. Is that normal? Quote Link to comment Share on other sites More sharing options...
BigRedX Posted February 16, 2013 Share Posted February 16, 2013 [url=http://www.adeson.co.uk]Talk to this man[/url]. It doesn't sound right to me. Quote Link to comment Share on other sites More sharing options...
Dr M Posted March 1, 2013 Share Posted March 1, 2013 In a word, no. There's nothing particularly special about the construction of Tri-Sonics, so the impedance should be in line with a (a fairly hot) strat pickup. It sounds like there's a short in the windings somewhere. Quote Link to comment Share on other sites More sharing options...
tommorichards Posted March 1, 2013 Author Share Posted March 1, 2013 yeah. i talked with that guy. Says it looks like someone has tried to do something with the coil, and basically broke it and now the coil is shorting or summat. Drat. paid £25 for the sucker Quote Link to comment Share on other sites More sharing options...
3below Posted March 1, 2013 Share Posted March 1, 2013 If the main body of the coil is still in its paper / plastic wrap (I forget what, was 1975 or so when I took mine apart to look inside) then the coil should be ok. You might have a short against the metal case. Take it apart, remove the coil from the magnets (it is very simple construction if an original one). Try measuring resistance. If in the K ohm range (as mentioned above) the coil is ok. If the coil is ok when outside the case, coat the wires in something like varnish or nail varnish. This will hopefully sort it.

tommorichards Posted March 2, 2013 Author Share Posted March 2, 2013 Its wrapped in paper and covered in a varnish. Looks sealed, and measures the same outside the case. Quote Link to comment Share on other sites More sharing options...
BigRedX Posted March 2, 2013 Share Posted March 2, 2013 Can Adeson not fix it then? Quote Link to comment Share on other sites More sharing options...
tommorichards Posted March 2, 2013 Author Share Posted March 2, 2013 yeah he could. £20. But that'll be £45 for this pickup if i do, and im not sure im there yet Quote Link to comment Share on other sites More sharing options...
BigRedX Posted March 2, 2013 Share Posted March 2, 2013 Fair enough. I love the sound of mine, but only as a pair wired in series... Quote Link to comment Share on other sites More sharing options...
3below Posted March 2, 2013 Share Posted March 2, 2013 Very unlucky by the sound of it, probably a short. However it can't be far in, say 6K ohms and 7500 turns for whole pickup. This gives about 1 ohm per turn. Are you brave? You might get lucky by removing say 10 turns - problem is which end to remove 5 turns from. The danger of this approach is that you may destroy it forever and it may not fix the issue. It depends on how the pickup coil was wound. It may not be possible to remove the offending wire to remove the short. Another desperate measures method - am not sure if this will work. Polyurethane varnish (spirit based), dilute until incredibly thin. Immerse pickup coil, leave several days. Remove, allow to dry. You might get lucky and varnish gets into the 'short'. Good luck Quote Link to comment Share on other sites More sharing options...
BigRedX Posted March 2, 2013 Share Posted March 2, 2013 It could just as easily be on the inside 10 turns. Quote Link to comment Share on other sites More sharing options...
tommorichards Posted March 2, 2013 Author Share Posted March 2, 2013 Thanks for the ideas, but I don't think I can get the tape off without messing the coil up. I may just send it to the guy. It's been a while since I bought it so I think the cost will feel diluted if I send it Quote Link to comment Share on other sites More sharing options...
3below Posted March 2, 2013 Share Posted March 2, 2013 [quote name='BigRedX' timestamp='1362236360' post='1997374'] It could just as easily be on the inside 10 turns. [/quote] Agree, that what was I was trying to say with which end to remove turns from. You said it more clearly - inside or outside windings. Ask the guy can he rewind without original coil - he will have some originals to work from. If he has, you now have nothing to lose and £20 to gain (other than time, faff and possibly varnish everywhere). If he can rewind try the DIY first. Nothing to lose, beer money to save...
