Yashica 14E batteries and adapter?

[georgemvg]

Hi all! I just made a big mistake. I thought that 14E was using px675, but I was wrong. I 've already planned to make that battery adapter with the schottky diodes, but everything was in vain. Now whta I do? Can the Lynx use batteries with 3 volts or it neads exactly 2,7volts? If this is the case, is there an adapter that provides a voltage decrease? And the Monster is allready home and I have not used it yet...

It's a guess, but the 3 volt batteries will probably work just fine. Your exposure might be off a fraction of a stop. Check it against another meter. You can alway set the ASA/ISO speed so you're getting the correct exposure.

I used a .410 shotgun shell

cut it off just above the copper base..punch out the primer and put a rivet in the hole. A 3 volt battery just drops inside and the shotgun base goes into the hole first.

Cheap... easy... works.

But then there IS THIS from The Cameraquest site...

The Lynx uses two PC640A batteries...strangely enough, they are still available.

Imagine that????

I think they are referring to alkaline 640ties. Proper mercury 640ties were discontinued in 2000.

BTGC... You are right... I should have known that.

I've had a half dozen Yashica's. One of the sites that gives a lot of information specific to the Yashica rangefinders is

www.yashica-guy.com/index.html

There are links to battery solutions, battery adaptors and other information for a large number of the old Yashica's.

Another thing about the batteries for this camera.
Sometimes the carbon tracks for the meter on the aperture and shutter rings are worn out.
Unless it is known that the meter works o.k it can become a very good manual camera for using in the sunny 16 mode, and at a pinch with a seperate meter. 🙂 I think I would use a meter for low light shots.

I got an hand meter, but I really wanted the meter to work. Maybe I 'll check with an external power if it works and begin to search the whole thing again...These carbon tracks can be replaced? I can do it alone if I know the source of these things...As far as the yashica-guy is concerned, he doesn 't say much about the Lynx adapter and if it also decreases voltage. But if he says so, maybe the adapter is working as intended...😉 Kuzano, I can't understand much from your method. If you can, please give more info.

This is not true. I know for shure that GP still produces them.

This could be true, another thing if and where you can buy them. Maybe they are still produced for domestic market? Maybe you have found dead stock? Officially no one carries them, maybe individuals are reselling them.

Last year I locally bought a few 1.3V Varta PX675's, one of them powers up external light meter.

btgc: A friend of mine bought them in Hong-Kong for me. They are Silva branded on the blisters and GP on the boxes. (10 blisters á 6 button cells go into a box)
It is no wonder they are produced and avaible where they are not forbidden. They are forbidden to be produced in the E.U. but selling them is permitted. I don't know the exact situation in the USA, for sure they are forbidden to be produced, but what's the situation with selling them? (I ask also out of pure selfinteres as I sometimes sell these batteries and have a lot of ppl. from the USA asking.)

I use 4 LR44 batteries (yes, 4) to get 6V. Stack it together, put some wrap around them and put it in.
Then with a small TO-92 size transistor, LM 317LZ, and 2 resistor, I made a simple 2.7V voltage regulator, and put it on the base area. There are enough space there to put the voltage regulator (don't forget to put some tape to prevent shorting). On mine, the red cable that connected to the metering circuit is the power source from the metering switch, so use that one as the source of regulator.

the regulator it self will regulate with 5mA current, but the best of Lynx is that light meter is not working if you don't press the switch, so 5mA for few second will not drain the battery too much.

I have tested on mine and the regulator work very nice. Unfortunately I have another problem that the resistor plate in aperture/speed ring is having intermitten contact. Too bad I can't use the regulator.

at the end, a small 20$ gossen pilot meter attached to the hotshoe solve my metering problem..ha..ha..

here is my small gossen attached on the mammoth lynx

nice combo !!!
