MF x10v3 ...heads up !

[zanash]

Having open up one of these beasts it's clear to see that the four transistors in the output are cooking the pcb. There is considerable disclouration of the pcb track [tranies using these to sink heat away from themselves]. If this is left unchecked it may cause failure of the unit.

I would use a heatsink like rs part 507-4753 .

I've bought this up as a "heads up" for anyone who has this unit, and therfore should check it out.

Can you post some photos? I am just curious. Thanks.

This is the area acting as a heat sink beneath the transistor.....not to bad yet but its still got damn hot to get that far......[this is just one of four]

Further to the info provided I 've now measured the temp after five minutes and the transistors have reached 80 degree C and the stand off resistors are very hot too 50 ish C.
