johnyboy Posted March 4, 2011 Posted March 4, 2011 Ive recently purchased the Alto amp with a blown channel.Does anyone know of any common faults ?Or if there are any internal fuses? Quote
Jaz Posted March 4, 2011 Posted March 4, 2011 Brand new? Send that shit back if it ishave bought 2 amps brand new that were broken, 1 of them channel 2 wasnt working (mind you they were cheap shit) Quote
johnyboy Posted March 5, 2011 Author Posted March 5, 2011 I purchased the amp knowing it was faulty got a very good deal........ Quote
SourceRaver Posted March 5, 2011 Posted March 5, 2011 Half price?....Open it up and have a look for fuses, broken wires, burn marks etc. Have a smell as well and see if you can detect burning plastic (ie someone has let the magic smoke out). If nothing is obvious then your looking at a trip to the electrician.Otherwise use it as a dedicated single channel amp for a passive sub. Quote
johnyboy Posted March 5, 2011 Author Posted March 5, 2011 Ive pulled the amp apart and had a close look and noticed that tha capacitors are leaking fluid i will post pictures soon the caps are http://parts.digikey.com/1/parts/137459 ... 3a052.htmlthere are 4 of them and they all look to have been leaking black fluid and have changed shape as well and appear to be knackeredthe fuse on the blown channel is oki was wondering what other components could have been blown or afffected by the blown capacitors Quote
johnyboy Posted March 5, 2011 Author Posted March 5, 2011 when i say changed shape i mean i have noticed that there has been a problem inside the caps and it has caused the caps to appear to have blown from the inside . Quote
pill Posted March 16, 2011 Posted March 16, 2011 it could be at any and all components on that channel.You should contact alto for the circut diagram and get an electrotech to test at various points. Quote
johnyboy Posted March 17, 2011 Author Posted March 17, 2011 Thanks pill.i was hoping someone could advise me before just replacing the capacitors and wasting my money.do you know any technicians in melbourne that could assist me in finding the fault?or can you put me on to someone that could do the relevant tests? If i had all my testing equipment and multi meter testing gear that i have in the uk i would test it myself, but i do not have the funding to purchase this gear at the moment Quote
pill Posted March 27, 2011 Posted March 27, 2011 sorry i didnt reply sooner. unfortunately i only know people in perth, really its only worth getting it fixed if you know an electro guy, EAV (the main repairer here) charge a minimum 80/hour to look at stuff Quote
johnyboy Posted April 24, 2011 Author Posted April 24, 2011 Ive found someone to have a look at it for me.hes a sound engineer and we repair their company vans so could get a right result.think im gonna leave it for a while though bit short of cash at the mo. it works fine on 1 channel for now anyway.

johnyboy Posted May 6, 2011 Author Posted May 6, 2011 I took the amp to this fella on monday .Before i took it there i loosened all the screws on the top before taking it there and when i picked it up yesterday he said he took it apart but his engineer friend didnt have the correct test equipment to test it and he confirmed that the capacitors were definatley blown..so when i got it back home all the screws were still loose............so he didnt even take the fucking thing apart......wanker Quote
