    Does anyone know these portable HDD recorders? Apparently these are used in conflict zones like Afghanistan, Irak, Somalia, etc. (... someone told me ...) but I wouldn't bet to much on it. They are in fact nice sounding, highly professional and quite expensive.
    I have one of those for repairing on my desk, so here it goes:
    It comes with a "Power Pack NV-LIB" and here are the 1st two (solvable?) problems: right after the charger input connector is a 5A fuse soldered on the circuit board. Blown out, needs to be replaced. Right after that is an IRF4905 "Hexfet Power Mosfet". Also blown, also will be replaced. I just hope that after replacing these 2 parts they won't blow up again.

    Now the main NAGRA V unit: it refuses to turn on, even with a good power-pack. I opened it and checked internal connections, then fuses F1 to F3 (those are all the fuses I could find so far) and so far everything seems to be OK. Are there any more fuses on the main board?

    Unfortunately I don't have any kind of schematics on hand and before I mess around with that thing I prefer to ask you guys.

    Thanks in advance,

    Sorry don't know snot about the new gen Nagras, but your post flashed me back to using Nagra IV-S reel to reels on location sound for industrial films. They were very dependable units and the choice of many in the film industry, this may be the use for these newer recorders as well. They were set up to sync with the cameras. 20811
