So I bit the bullet and bought the MR-44 adapter from smallbatterycompany out of UK, first thought it wasn't working but then verified it does deliver 1.35v under load.
But... it makes ZERO difference in any of my 3 cameras: Auto S3, Hi-Matic 7S II and Olympus 35 RD. The meters read absolutely the same as with the LR44 which is your usual suspect small 1.5 alcaline.
I get absolutely the same readings.
Maddening stuff. Especially considering the price of the adapter.
Why do you guys think this is the case?
Also, I have actually discovered that my S3 (very recent acquisition) underexposes by 2 stops anyway, regardless if it's light meter is fed with 1.5 or 1.35v.
Also - it seems that EVERY Auto S3 already has the diode installed in it's battery compartment from the factory - http://wkoopmans.ca/notebook/wp-content/uploads/2018/12/KonicaS3repair2.jpg
Mine does too, is it possible that Konica made them like this? I mean, if this is as such what would be my solution here - to install another diode in series?! OR just some other diode with higher voltage drop?
Cheers

If you are comfortable pulling the top off you can recalibrate the meter on the Auto S3. There is a fixed resistor near the meter that you can swap out to adjust the reading. It has been a few years but I think I reduced the resistance to increase the exposure.
The other option is to just set your film speed two stops lower.

Thanks Shawn!
I am comfortable with it I just am unable to find a spanner wrench that'll have the lower span limit of less than 10mm!!! Because I believe I need something like 8mm to be able to open the rewind top part thingy

I think I used a pair of pointed tip tweezers for mine.

My first small spanner was fashioned out of a cheap pair of kids scissors with the ends ground flat to blades.

Using side cutters, trim a paper clip into a U shape. Makes a narrow wrench for retaining caps and such.

Great ideas for a DIY spanner wrench guys, much appreciated!
