After being told that the 8 pin mini Din cable between an ASR-10 and an OEX-6sr was a bog standard 1-to-1 cable, I purchased one plugged it in and then had all sorts of hum which ended up with fuses F6 & F7 blowing. Replaced those and then used the Service Manual to check things in case something was wrong. Discovered when talking to The Soniq that the cable is not a 1-to-1 cable. I got the correct wiring and have since corrected my cable. However, something has happened to my power supply board. I got an ERROR 009 today when turning the ASR on and that fits with what I was seeing with connector J3 voltage tests. It now reads zero across every test on the J3 socket. J1, J2 & J4 all test within the ranges in the service manual.
Is this likely to be something on the board or is it possible that a transformer can give up like this? I presume that there are different takeoffs from the windings of the transformer so I would expect that if some of the voltage checks on some connectors are ok and on J3 is not, I suspect some other components may be at fault?
I am not well versed electrically. I know enough to be dangerous, but that is about it.
I can tell you that none of the components appear like they have overheated. None of the large capacitors appear bulged. There is no evidence of any sort of ooze or chemicals on the board at all.
Does anyone have any idea what I should be looking for?
