Happy holidays
    I had Garry CLA 2 bodies about 3 months ago. So far, so good. I'd use him again.

    Thanks,
    Garry's fixed my Minolta X-700 and gave it a CLA for $50, after another shop had said that the camera couldn't be economically repaired. So I'm a satisfied customer.

    How about using an adjustable step-down regulator with with some kind of higher voltage battery like a CR123. That way the voltage is always 1.55 or whatever you want it to be.

    The 123 won't fit in the camera, it was made to use a single button-cell battery. You could probably do it if you were willing to accept having a battery box hang under the camera, or have it in your pocket with a cord to the camera. Someone online designed one like that for Olympus OM cameras. It doesn't have a regulator because the OM 2s and OM 4 have built in voltage regulation and were designed to work with two 1.5 volt batteries. So, his design used two AA batteries..the purpose was to improve cold-weather performance because cold reduces the voltage a bit with the little silver-oxide buttons the OM cameras used, and AA batteries are more resistant to cold.

    Works like a charm. LP2951 adjusted for 1.35V running from a Lithium 1225 button cell (fits in a 625 battery compartment). Needs a proper on/off switch because of the quiescent current.

    Having given advice earlier in this thread I now have to do this modification myself as I have just acquired a couple of SRT100 bodies. I will post some instructions and pictures later (assuming it all goes to plan!).

    You could probably use the existing power switch on the SRT cameras. Unfortunately that switch also incorporates a battery check position which may not be re-wireable to operate with a regulator.

    I did this modification (LP2951) for a lightmeter with CDS cell (Weimarlux CDS from GDR) which has a pushbutton to activate the metering.
    For my SR-Ts I found it more easy to recalibrate one to a silver cell (recalibration had to be done anyway); the other one is still on mercury and will be adapted to 1.55V when the battery goes down.

    Alternatively I will simply place the diode in line between the battery compartment and the switch. Easy to reach after unscrewing the bottom plate.
    Regards,
    Andreas

    That's what I'm going to do. I have ordered some PX625A cells which are 1.5v cells in the same package as the old mercury cell.

    Make sure, that the Battery is not only 1.5V but also silver. Alkaline is not stable enough for this. AFAIK the PX625A is alkaline.
