Twigman Posted March 27, 2018 Share Posted March 27, 2018 I think the electrolytic capacitors in one of my KRK RP6 G2 monitors need replacing. It crackles whenever it is powered up whether an input is connected or not. Is anyone local to me (Dunstable/Hemel/Watford/Luton) who could do this for me?

Sibob Posted March 29, 2018 Share Posted March 29, 2018 The service centre is in Acton if that helps: http://synthservice.com If you need a spare part, you would need to purchase it from them anyway (or possibly directly from Focusrite (UK distributor) if the service centre don't sell outside of a repair). But whoever fixes it would possibly need the schematics, which wouldn't be released by KRK or the service centre. Si 1 Quote Link to comment Share on other sites More sharing options...

TheGreek Posted March 29, 2018 Share Posted March 29, 2018 I use an Amp tech in Stevenage if Si's suggestion doesn't work out. Quote Link to comment Share on other sites More sharing options...

They seem to think from the fault I describe that the monitor is 'beyond economic repair'. cow poop a couple of capacitors for sure - so they want me to replace BOTH my monitors GRR!!!! What a waste!

You’re certainly able to ask any tech to take a look, all i’m saying though is that they won’t be able to get hold of any schematics if needed. Spares can be purchased from Focusrite I believe.

stevie Posted April 9, 2018 Share Posted April 9, 2018 https://sbsav.co.uk/shop/44811-krk-rokit-rp6-g2-amplifier-module-amp-pcb-board.html They also sell spares, but by the looks of the amp you should be able to use caps from any reliable source. There is quite a lot on YouTube about fixing these, including this one which may be of interest: Quote Link to comment Share on other sites More sharing options...
Twigman Posted April 9, 2018 Author Share Posted April 9, 2018 My symptoms sound exactly like this: (RP5 in video - mine is RP6) Quote Link to comment Share on other sites More sharing options...
BreadBin Posted April 9, 2018 Share Posted April 9, 2018 I have an old set of Rokit 8 which have buzzes now and then, I keep meaning to research capacitor upgrades but never get round to it - just turn them up! Quote Link to comment Share on other sites More sharing options...
Twigman Posted April 16, 2018 Author Share Posted April 16, 2018 I tried the repair myself. It's worse now than it was LOL I've ordered some new monitors. Hide my soldering iron - I'm obviously totally inept Quote Link to comment Share on other sites More sharing options...
stevie Posted April 16, 2018 Share Posted April 16, 2018 Sorry to hear that. Looking on the bright side, you may have learned one of the great life lessons: "know your limitations". Quote Link to comment Share on other sites More sharing options...

Twigman Posted April 17, 2018 Author Share Posted April 17, 2018 I followed exactly the procedure in the youtube video stevie posted I used Wurth capacitors from RS Now I have exactly the noise demonstrated by this video (the video is RP5 not RP6 but the noise is the same) Quote Link to comment Share on other sites More sharing options...
SubsonicSimpleton Posted April 26, 2018 Share Posted April 26, 2018 Take a look at this, the problem could be being caused by something other than the caps. Quote Link to comment Share on other sites More sharing options...
MoonBassAlpha Posted April 26, 2018 Share Posted April 26, 2018 Interesting video, and if you read into the comments, a guy from KRK pops up and says the engineers there had seen this conductive are corrosive potting compound in their products, which was not specified in the build standard. Get scraping! Quote Link to comment Share on other sites More sharing options...
BassHertz Posted April 28, 2018 Share Posted April 28, 2018 Repaired quite a few of these. Just like in the EEV Blog video, you have to get rid of all the black glue/compound and then all the crackling goes away. Once its all gone check the legs of the components as some times they get corroded by the glue. Quote Link to comment Share on other sites More sharing options...
MoonBassAlpha Posted May 2, 2018 Share Posted May 2, 2018 look out for a set of Rokit monitors in the For Sale section soon folks! Quote Link to comment Share on other sites More sharing options...
