The tech managed to squeeze in a separate power supply (powering this board over USB is not a great idea, I've heard that before) - and the results are fantastic. It's connected in parallel to the existing S/PDIF input. The same board is used by quite a few high-end brands (Thrax Audio for sure, can't name the others). So the Ordinal got a brand new XMOS board - i2soverusb by a local company named JL Sounds. All caps were replaced with long-life Rubicons, I liked the sound a lot - but had not much use for the Ordinal, since 95% of my digital music is on a server, not on CDs. After months of struggle with the faulty left channel (post #795), I finally found a capable technician who found the problem in a couple of hours. Well, I'm not sure JW has ever heard about this version, but I got it now. The PCB indicates 8v2 on the tab of one of them if memory serves correctly.Ĭan't help to show off a bit: did you know there was a special limited edition of Ordinal with a USB input? The single transformer on the right side (looking from the front) is for the logic and is usually a couple of 9v windings in parallel (but I have seen a single higher current 9v winding used), fed into a bridge rectifier and then a couple of 317 to-220 package regulators. If the PCB tracks are corroded by rotten capacitors and you did repairs then checking that you re-instated the tracks correctly could be another place for your attention (The PCB is simple enough but I can tell you from experience that it is difficult to get a picture of a PCB that hasn't rotted so that you know what to aim for, only later issues of the board had capacitors that didn't leak and rot the PCB's). If one has a low rail it is likely being dragged down by excessive loading (did you replace all those old 2200uf capacitors?). The two transformers on the mains card should all be putting out about 19v DC (after the rectifiers).
