Solving the Yashica T'Chunk Issue.

[NickTrop]

Not sure if anyone ever posted this. Apologies in advance if this has already been posted or is old news.

If you own a Yashica Electro GS/N, you know that the camera makes an audible/infamous "T'Chunk" sound when you advance the film, which somewhat defeats the verrry quite "click" of the camera's nearly silent leaf shutter.

I read on another forum (somewhere, I forget) that if you apply a little pressure with your index finger on the trigger as you advance the film, the "T-Chunck" goes away, and the film advances silently.

If you're unaware of this and have an Electro, try it.

Well it works.

nice trick, tks for posting it!

i'm just wondering what this would mean to the inner workings of this model. will this cause any damage? it'd be nice to have positive knowledge on this, then i'll do it without always have a shadow of doubt in the back of my mind.

also, if the camera functions correctly, that means the POD is ok, is this correct?

Greyhoundman is the guy to ask, but about the POD: my camera functioned fine for about eight months and twenty rolls of film before starting to show Pod problems. It had been stored in a box for ages, so the pod probably did die. It just took some time and use to develop the problems that come with it.

(My GSN is on it's way to the Gman as we speak 🙂 )

Isn't the clunk issue caused by the failing foam pad?

Also, I noticed that the shutter button mechanism is coated in oil that ages and gets sticky. I had the top parts off of three of my cameras friday and used lighter fluid to eat away the oil, but they still clunk between shots.

I'd have to dig down deeper to find the root cause, and I'm not sure I'm qualified yet 😉

It's totally safe if you hold down the shutter button, but I don't hold it down all the way. Like greyhoundman said, it's just you holding down the shutter to act like a shock absorber when that mechanism comes flying back up to the shutter button.

I think (someone verify) that the clunk is just the way it should be.

Odd thing is My Elctro Pro doesn't clunk, the exposures seem to be right on. The GSN does clunk, yet it sometimes overexposes, even when I have no over under lamps on. The GSN is also the one that seems to sizzle a lot.

What do you mean by sizzling? The overexposure light sizzles on mine at times when I am close to 1/500 but not actually over yet. I can hear it as I am pushing the shutter release button down.

You are describing the sound I hear in my GSN. I understand that the sizzle is common and is not likely an issue, and it takes some work to elimenate.

Good news. If it is not an issue I'll just leave it be. I thought it had to do with the pad.

I'm just a novice at this, but the latest GSN I picked up crackles because the electrical contacts of the over/under lights (i think) is bad. I forgot to spray contact cleaner on the leaf switches when I had it open. I will open it and try to clean them tonight to see if it makes it go away.

wow, thank you all, G'man and everyone else, for the replies! just a great wealth of information!

now i know more and better about this camera. the one i just got functins fine. earlier, i was wondering whether the POD should be replaced with a new POD even if it's fully functioning. guess there's no need for now.

i'll be using the finger-shock-absorber method with it then. let's see how long the POD will last.

great group, thank you all!
