Emax

CFAH1602C-TMI-JT
crysal fonts this has the blue screen its the same spec as the powertip one

but it is 13.6 mm deep where as the old 1 is 8 mm deep

if its the rack you have to modify to get the correct voltage for pin 3 

you have to remove the inverter chip and both caps then you have to link the 5v of the inverter chip input to the in leg of the trim pot then you have to replace the cap on the out going leg  but it has to be reverse polarity as it was doing -5 vdc before where it shows a + sign on the pcb you have to put the - leg of the cap and the positive leg where the - leg was this

is for the 5v operation now use the trim pot to vary the contrast of the lcd display

also you have to extend all the buttons on the emax and the 2 sliders due to the lcd being 6-7 mm bigger

than the last 1

  I know this must have been discussed in the past, but have a look at this prophet VS and scroll for the Emu SP-12, can someone more technically inclined point out the model that might work with the Emax Rack?

  That would be so great.

  Thanks

  Thanks. I really hope that's all it is :)

  I'll open it up and have a look as soon as possible. 

  Silly question time: how does it open up? I don't want to remove the wrong screws and find that I've removed the motherboard or something . . .

  I've never had one of these open before, so is there anything I should know before I do? I assume from the sheer size of the thing that it's not exactly cramped in there?

  Thanks,

  Daniel
