They still support and do repairs last time my mates DM70’s went down, about a year ago.

Halcro DM10 repair
Does anyone knows how to repair the Halcro DM10 preamp in U.S.? My Halcro DM10 recently has no sound coming out of left channel when in the middle of listening session to the phono (it is not tuntable since I swapped the interconnect cable), line section appears to have no issue. The only way to solve this issue is to power cycle the unit, then it sounds just fine for another couple hours before left channel stops working again. Since there is no degradation in the sound quality and power cycle can solve this issue. This tells me that the audio circuitry in the analog section appears to be fine. The problem appears to be in the microprocessor control section, possibly the relay. I am trying to open it up but I do not know how to open it since it has no visible screws. I am wondering does anyone have the experience to open the Halcro preamp/amp? or does anyone knows how to get the schematic? I heard Halcro is out of business and I also do not wish to sent it to Australia if it is a simple fix.

Not much good news for you unless you live in Australia..... Halcro did go out of business and despite at least two attempts (to my knowledge) to re-establish themselves....are still defunct. You can open both the DM10 and DM58-68 amps by way of allen key screws accessed through the slots between the vertical aluminium heatsinks on the side of the amps. But this is what you will find inside http://i.imgur.com/aViBjTL.jpg PCBs covered with resin to protect the proprietary circuit design that Halcro owns. And despite the fact they are defunct...they will not release the designs to enable others to work on these circuits. Here are the contact details of the original circuit design engineer in Adelaide who still services the Halcro gear:- Lance Hewitt Independent Technical Consultant +618 405 16 39 39 Good luck. |
