HarryPotter Posted January 14, 2008 Share Posted January 14, 2008 Right, I had a friend bring me the titled bass and announce it's 'broken' but that he had tried to fix it but its still broken. Oh God, this is gonna be bad methinks. So I open it up, and aside from 2 of the wires being broken to the jackplug and the other hangng on by the skin of it's teeth it looks OK. So battery out, replace the duff wiring put it back together and nada, it's dead. Nothing else seems amiss, and yes I did get the wires the right way around. So is it possible that the little potted block and the circuitry therein is dead? If so how do I check, and where can I get a replacement from. He has 2 big gigs coming up so any help would be greatly appreciated. TIA. Quote Link to comment Share on other sites More sharing options...
BOD2 Posted January 15, 2008 Share Posted January 15, 2008 It's possible, but these things are usually quite robust. The jack socket controls the power to the preamp, so if there is anything wrong there then no power will get to the preamp. The jack socket will have three wires going to the tip, ring, and sleeve connectors on the socket. The tip is the "hot" output from the preamp. The ring and sleeve connectors and joined together when a mono jack plug is inserted so one wire should go to the battery and the other should go into the preamp. Double check this wiring first and make sure the jack socket itself isn't damaged in any way. Quote Link to comment Share on other sites More sharing options...
Peaty Posted January 15, 2008 Share Posted January 15, 2008 Worth getting a meter on it and check that the power is getting at least as far as the jack. I had a similar problem in the past that turned out to be a duff battery connector. pete Quote Link to comment Share on other sites More sharing options...
