KiOgon Posted December 22, 2009 Share Posted December 22, 2009 I've been getting intermittent crackling through my TE Boxer on & off for a week or two now, but the 51'P powerhouse seemed to bring it on big time. Every time I tried tweaking a pot, tried another bass, another lead, etc etc it seemed ok for a minute - then started again. I ordered some Servisol yesterday & it came today, (brilliant ebay seller = Knights-Electrocom). With the 4 screws out of the cabinet top & the amp slid forward, I could just see the holes in the pot' housings were all underneath facing the amp chassis, so to get a good squirt of cleaner in the right place I was going to have to remove the PCB assembly. Easy enough, first I had to get the speaker wires out the way, pulled the white wire connector to remove it - with a little wiggle & shizzer! the complete tag pulled straight out of the board! A classic dry joint. There was never any solder on the tag - completely clean looking - never been tinned! A minute cleaning the legs up with a file & a hot soldering iron - soldered back in - proper job. Squirted all the contacts anyway, cleaned up & re-assembled, must have been a 1/2 hour job. No more crackling - no more buzzing - but holy schomoly! Does that P bass have some thump? + it's like having a new amp Just everything else in the room vibrates now Cheers & Seasons Greetings to all, John Quote Link to comment Share on other sites More sharing options...
stingrayfan Posted December 22, 2009 Share Posted December 22, 2009 Well done - those Traces seem prone to a dry joint. But once working, sound great. Quote Link to comment Share on other sites More sharing options...
