[OM] Light meter : recalibrate from PX625 to 357 cells (help!)

I'm hoping Tim Hughes can weigh in on this if he is still on-list. I have an old Weston Ranger 9 light meter that used mercury 625 batteries that were 1.35 volts. I'd like to conver it to the silver oxide 357 cells our OM's use.

Other than spending $45 for two MR-9's, is there any way I can add a resistor in-line somewhere in the meter to do the same job?

Anyone done a DIY battery conversion?

Any ideas would be appreciated.

Thanks, James.
