Booga13 Posted July 27, 2020 Share Posted July 27, 2020 So I think I've fried my SPB1, I was going to give it one more try before putitng it up for sale, plugged it in and there was a wisp of smoke and a burnig smell, (I REALLY must label my power cables...) Left it alone for a while and tested again, nothing with a battery and when it's plugged in the correct power cable the low battery light comes on but nothing else. I'm not the original owner and it's out of warranty anyway, now given that I was probably going to be selling it anyway I don't want to to sending it back to Sadowsky for a potentially expensive repair (if that is even posible) + shipping costs 2 ways , is there anyone here on BC that would be willing to take a look at it or are there any shops/individuals you would recomend for an appraisal/less expensive repair? 1 Quote Link to comment Share on other sites More sharing options...
Hellzero Posted July 27, 2020 Share Posted July 27, 2020 There should be a diode preventing the cooking of your pedal when reverting the power supply. Chances are that it's only this diode that has burned... Chances... Quote Link to comment Share on other sites More sharing options...
Booga13 Posted July 27, 2020 Author Share Posted July 27, 2020 Ooooh, that sound like good news, my electrical skills are limited but not non-existant so I'm happy to try and fix it, just need to find a schematic, I'll have a hunt this evening when I'm not working Cheers Quote Link to comment Share on other sites More sharing options...
Thunderbird Posted July 27, 2020 Share Posted July 27, 2020 There's lots of people who built pedals on here there's a thread in the effects section that might be useful to you Quote Link to comment Share on other sites More sharing options...
ahpook Posted July 27, 2020 Share Posted July 27, 2020 (edited) There's a layout for the circuit here at Tag Board Effects, if that helps, although it seems that it misses out the protection diode ! Might be worth looking for D1 if the parts correspond. Edited July 27, 2020 by ahpook Quote Link to comment Share on other sites More sharing options...
paul_5 Posted July 27, 2020 Share Posted July 27, 2020 IIRC there’s only 6 or 7 components that could fry, so should be a relatively easy fix Quote Link to comment Share on other sites More sharing options...
