Help needed - Connecting Aux Voltage (HG Supply) to UCD400AD Ver 6.1þ
I saw on the Hypex website the article regarding connecting the auxiliary voltage of the HG power supply to the amp modules and wanted to try it out.
In the article it says to remove 'via' by drilling through the PCB. I checked my HG supply but there is no 'via' printed on the PCB. In that vicinity, I did see something like a component lead sticking out on the board. Is this the 'via' that the article is talking about? The article also says remove transistors BDX33 and BDX34. On the UCD400AD Ver 6.1, these should be T16 and T17? Would appreciate any advice/info anyone out there can share. Thanks!! |
