Re: Canon Pocketronic - Power Supply Message #2 Posted by Katie Wasserman on 24 Oct 2011, 7:08 p.m., in response to message #1 by Joerg Woerner
Joerg,
It's a split supply with -10.5 volts and +9 volts. Only the row of 3 pins on the power connector are used, the center one is ground (I don't recall which of the two is + vs -).
While you could use a single supply of 19.5 volts I would not recommend it. The -10.5 volt supply charges the 7 x 2/3AA cells while the +9 volt supply charges the 6 x AA cells. Since they have different capacities you'll either under or over charge one set of cells. However, if these are old cells that need to be replaced anyway, go right ahead.
It's possible to replace all the cells with AAA cells in plastic holders. Somewhere on this forum I described how I did this.
