TKenrick Posted August 11, 2011 Share Posted August 11, 2011 Just turned on my Little Mark II to start practicing and it's making a disconcerting buzzing noise, I think it might be coming from the fan. Has anyone had similar problems? Will ring Proel but as it's out of warranty I'm tempted to open it up and have a look... Quote Link to comment Share on other sites More sharing options...
Monckyman Posted August 11, 2011 Share Posted August 11, 2011 (edited) Have a good listen to the fan first, the bearings do wear, (if they are like all the other amp fans). Are you sure it`s mechanical and not electronic? If you are sure, and it`s out of warranty, open it up and find a replacement fan. I did this with the two on my Ashdown abm, and found direct replacements at a PC parts outlet. They were marketed as being silent. Made a massive difference to the ambient noise. Looking at the fan on mine, it appears to be the same standard mini size available in every pc shop,just take yours and compare the voltage and polarity and make sure you put it in the right way so the fan pulls the hot air outwards.(label outwards). Will cost app £5.00 for a "silent" one. Heres a pic of the LMK II with the top lid off On this one you cab see the fan power cable and connecter (small black and red cable that splits off at the right of the cable run. You`ll have to snip the two cable ties that keep this bundle tidy, and put two new ones on once the new fan is in place. On this one I pulled the Neutrik NL2 socket cables away from the fan, and the power cables up so they sat on the ali heat sink,you can see the gap the fan just about fits through. Finally I pulled my fan out to see how hard it would be, and it`s a bit fiddly, but not difficult as such. I included the fan pic so you can order a direct replacement without removing yours. HTH Good luck! MM Edited August 11, 2011 by Monckyman Quote Link to comment Share on other sites More sharing options...
TKenrick Posted August 11, 2011 Author Share Posted August 11, 2011 Thanks for the advice on fans. I'm fairly certain it's mechanical - the buzzing stops if I tilt the amp or put it on its side. I'll open it up later and take a look. Quote Link to comment Share on other sites More sharing options...
Ou7shined Posted August 11, 2011 Share Posted August 11, 2011 Probably just needs hoovering out. These wee amps pull in a ton of dust and crap and stuff. Quote Link to comment Share on other sites More sharing options...
