PunkPonyPrincess Posted April 19, 2019 Share Posted April 19, 2019 (edited) Another lost cause saved from landfill. Roland PK5 Bass pedals, bought for £200 locally, non functioning. No battery pack, burn marks on battery leads. No PSU. Someone obviously tried plugging in the wrong one via the wrong input... Roland and Boss historically were a bit weird on their power delivery methods for pedals back in the day but a former owner has been even weirder. Proper 9V PSU obtained, new battery pack fitted, some minor track cleaning and repair, D1 diode replacement, fried (cracked) npn (Q3) to replace, hopefully nothing else downstream, caps all ok. can’t get a service manual (http://servicerepairmanuals.netlook like they are not functioning) so I am flying cautiously. And yes, the inductor tests ok. The (D3) 5v6 zener Is untroubled, I even read 9v up to the npn so I was cautiously hopeful the custom chip is ok. Parts arrived. Cleaned the board, made me a broken trace with clippings from the diode. Fitted a battery pack as well. worked first time Discovered to my great joy I can have multiple synths running, so a few classic old synth VSTs have all been chained to MIDI channel 2, (Taurus Plug-in seems to be fixed on 2) so tap into poly mode and *MASSIVE* sounds ensue... mellotron VST next...

PunkPonyPrincess Posted April 23, 2019 Author Share Posted April 23, 2019 (edited) I just put this up for sale in /classifieds because I found another poorly pedal in need of my restoration services, a PK6. £50 markup (with the the PSU at £7 and the battery Pack at £3 plus £3 for components plus my time) seems ok?

PunkPonyPrincess Posted April 23, 2019 Author Share Posted April 23, 2019 (edited) No, no, no I am not into that restoration for profit thing but I am a sucker for a fixer-upper. Only Mr Sting and Geddy Lee need two footpedals.

Still, no harm in giving life back to the broken things & earning a few pounds Helps to pay for the next fixer-upper!

PunkPonyPrincess Posted April 23, 2019 Author Share Posted April 23, 2019 (edited) That’s the plan for the PK5 and this bassline sweetie I just rescued. This way people know what it went through to get working again before sold... nothing to hide when your PCB is nekkid to the world.

itu Posted April 23, 2019 Share Posted April 23, 2019 Oh dear, I had a similar Prodigy long ago. Happy, that I separated from it. Not MIDI and nevertune as a factory option. Funny thing is that they ask funny prices of those just because it says moog. Quote Link to comment Share on other sites More sharing options...
Si600 Posted April 23, 2019 Share Posted April 23, 2019 Could you give any advice on repairing pedals? I've got an elderly Boss GE7-B where the status LED has gone AWOL? Quote Link to comment Share on other sites More sharing options...
PunkPonyPrincess Posted April 23, 2019 Author Share Posted April 23, 2019 Not really i’d need to see inside the thing and look at a schematic. Quote Link to comment Share on other sites More sharing options...

prowla Posted April 27, 2019 Share Posted April 27, 2019 I've got a set of PK-5A and they are rather good (though I would've preferred they were mains powered rather than using an external PSU). Once you learn the channel/patch/octave dance they are quite straightforward to use. I've got a 12-Step which I need to get to grips with; it's more of a program it via a laptop approach.
