2pods Posted October 4, 2021 Share Posted October 4, 2021 Hope this is in the right place, but anyway the mods will move it if not... Switched the gear on today (individually as usual, in case of overload) when I noticed no lights on my wee M-Patch 2 monitor controller It's a few years old, and came with a Euro 2 pin plug which I've been using with 2 to 3pin fused adapter. I've tried the 2 to 3 pin adaptor with my razor cleaning wotsit, and that works OK, so I'm assuming it's the actual adaptor. It states on the back it's an "AC/DC Class II Transformer, Input 230v ~ 50Hz, Output 15v DC 200mA, model D35-15-200" Not quite sure which bit of the input barrel to measure, but the diameter is big enough to nearly fit the width of one of 2 pins in. It also seems to be middle of the barrel positive and the outside negative. Any chance of a link to a (preferably UK) replacement ?

BigRedX Posted October 5, 2021 Share Posted October 5, 2021 (edited) Are you sure that it's the PSU that is dead and not the device itself? Do you have a multimeter for testing to see if the PSU is actually outputting anything? Edit: I've just had a look at a review of the device and the signal path is completely passive the PSU is only required for the status LEDs and the headphone amp, so if it's not working the the unit itself has died.

2pods Posted October 10, 2021 Author Share Posted October 10, 2021 Hoping to get a hold of a multimeter today. I've been put on to a suitable replacement psu by Martin W over at the SOS forums. Fortunately the unit itself is still working Quote Link to comment Share on other sites More sharing options...
BigRedX Posted October 11, 2021 Share Posted October 11, 2021 If the device is still working without the LEDs lighting up then it's most likely the PSU that has failed. Check the headphone output. If that's not working it's definitely the PSU. If it is working then something has failed in the LED circuits. 1 Quote Link to comment Share on other sites More sharing options...
2pods Posted October 13, 2021 Author Share Posted October 13, 2021 Great idea, as my Multimeter still hasn't turned up. I'll try it tonight. Thanks Quote Link to comment Share on other sites More sharing options...
