JT Dynamic PSU oddity
« on: 13 May 2014, 09:20 am »
Hello all, just a quick question regarding the above PSU, which l purchased with my Sensation M901 Russian PIO Cap upgrade) and it is quiet as a mouse, however when the same PSU is plugged into my Sensation M451 ( ClarityCap upgrade), it hums to high heaven, so much so that it is heard through the loudspeakers, any ideas as to why this is happening and are there any quick fixes for this, any help welcome and have a nice day.

Oh, man.  Strange.  Give Jason a ping. 

Do they both have the buffer?  Where the wires are placed could matter. 

We stopped shipping unregulated supplies to Europe because the humming was such a hit or miss.  Sounds like it's a miss with your M451.  Good opportunity to try batteries.  Look out for the 24v+ kits from the RC modeler guys.  2.1 x 5.5 mm bullet plug in-line wire is easy to find at digikey for $3.
