i have repaired a few hundred Jasic machines
they are no better or worse than Rtech.the hardware,i.e. case, handle, connectors, sockets, switches are all very cheap and are in no way comparable to better brands
EWM Lorch Miller,anything that costs real money, are designed to last, not just...
I wouldnt be definite that its the hf board thats at fault,just a guesstimate due to the sound in the videos above.i would ring technical arc or any other repair company and discuss it with them.it would be best to just send them the whole machine
There are a few revisions of the dynasty, the one i have here doesnt have points. I dont know would i go messing with modifying the wires around the ferrite core,miller usually get things like that right first day
