I recently had the 14V PSU for my Boss GT6B develop a fault - the strands broke where the cable goes into the strain relief grommet. I bought a replacement and it's the cheapest, flimsiest thing imaginable.
Then last night the 9V (but +ve cenre pin) PSU for my DMX lighting controller had severed through the strands at the same point where it enters the grommet. I made do for the night by stripping the cables back, twisting them together and wrapping in gaffer tape.
They all seem so cheap and fragile, even the OEM supples.
Can you get decent, robust PSUs? Can anybody recommend a brand?
