Minolta SRT electronic wires and pulley's

unwantedfocus · Jan 6, 2023

Hello photrio,

I've been trying to figure out what type of electronic wires the minolta SRT uses. Does a cable like THIS work? if so which one works? since there is a conductor resistance and a current, would prefer not t fry the camera. I could use a multimeter and measure it but I don't have one and even if I would have one I have no idea what to do with that information, my electrician skills are non existent.

What can I use to replace a pulley? I have one that teared because of the tension and looking for a replacement. been sitting on those two problems way too long already...

Thanks

I would look for a different camera.

this is just an old beater one to practice on....

I would also just buy a new camera. They are so inexpensive that it doesn’t make a lot of sense to fuss with that one unless you have some special attachment to it.

John Titterington fixed a severed cable on my SRT101. You might reach out to him. He also has an SRT101 for sale and his cameras are exceptional. I bought an SRT101and 201 from him and both were converted to use 1.5v batteries.

Any old wire will do in a camera. Especially manual cameras are extremely low-current devices so the nature of the wire is inconsequential. If it fits and solders fine, it'll work fine.

But I agree with the others: if you just want this camera to work and your repair skills are lacking, just get someone to do it for you or replace the camera (and perhaps sell this one for repair or parts).
If this is about learning to repair cameras, it's a different story.

Sorry, can't help you on the pulley; I suck as badly at mechanical things as you do at electronics

You can practically buy Minolta SRT parts bodies by the pound on Ebay. Look for a "lot" for repair, but it only makes sense if you really plan on continuing to repair SRTs...

If you mean the actual electrical wires, almost any small wire in the AWG 20-39 range would do in a pinch. BUT you metion a Pully? an SRT does use a tungsten wire (no Insulation) to coordinate the Glavanometer, the speed, and the aperture settings. It basically rotates the Galvanometer as part of the metering system. the wire runs on a couple of Pully pivots. Look closely at the service manual. if one of the pullies is damaged, at this point you would have to get it off a defunct spare camera. the Tungsten wire also has to be JUST the right size so the meter can be calibrated.

I bought a pack of 30-gauge wire in assorted colors from an *Bay seller: It’s a good size for many camera repairs, and wasn’t expensive.

On my SRT-101, the cable used in the system of pulleys is some sort of non-metallic, woven fabric. Not sure what I would use as a replacement, and some trial and error might be needed. The good news is that re-stringing and tensioning the blasted things is very do-able, but for me, there was a considerable learning curve, and IMO, this is one of the fussier aspects of SRT repair.

My concern with tiny silicone insulated wires would be potential to easily damage the insulation. I'd bet one could tear apart a 24g silicone insulation jacket by just pulling with ones fingers.

I think the cable is made of nylon and you can substitute radio dial cord used in vintage radio restorations.
