Hi All,
I have a QL19 with a bad meter. Looking at the camera and exploded service diagram (QL17), it looks as if the lens/mount needs to be removed. Is this correct?
Having never done this before, I worry about the complexity of the repair. So far I haven't had a camera beat me, but I've heard many a story about these, and how difficult they are to work on.
I wonder if I should just relegate this camera to manual duty. It works fine other than the dead meter and Auto operation.
Thanks,
Will |

If you are absolutely sure that the galvanometer is bad (i.e. shows no continuity - it should show a resistance between 1000 and 2000 ohms, and depending on the polarity of the instrument used the needle should move during measurement), you can replace it. Removing the front assembly of the Canonet is not a very big job. Remove the cover plates, and loosen the four screws on the corners of the recessed lens plate. One is partially hidden by the cocking slider, move the advance crank half way. Now lift the whole assembly, there are just some wires connecting it to the main body.
To remove the galvanometer loosen the small screw on the left side (seen from the front) of the galvanometer housing. Maybe there are a few parts more to remove from the needle trap mechanism, I have done this operation once only. Probably the needle trap mechanism will need some readjustment after reassembly.
However, this is not a beginners job. |

Hi Winfried,
Thanks for your help. Your tips were excellent. The galvanometer was indeed bad and I have since replaced it with a good working unit. I have everything back together except for the top and front leatherette as I have another issue with the camera I need to clarify yet. (another post :-) )
Here is a small photo journal I put together for anyone else considering doing this. It wasn't terribly difficult but not an easy job either. I guess you could say it was very time consuming! If anyone wants the hi-res pictures, email me and I'd be glad to send them.
