    Thanks, it was exactly that - it just need a prolonged wiggling with the curtain. Then the mirror went down. Sadly, next wind & shot & wind sequence resulted in jammed shutter again. This time there is a curtain "holder" (the one closer to the film plane) being visibly stuck in the middle of its travel. It's impossible to perform the finger trick again due the mirror being in position. I'm going to try to remove the bottom plate and check the internals for accumulated dirt as @kmac suggested. However, removing the bottom power switch requires a "pig nose" tool which I need to obtain first.

    Hello, one of my old Topcons has given up recently. During shutter action a really strange "springy noise" could be heard. Since then the mirror has been stuck in the top position and the advance lever can't be moved by more than a few millimeters. Initial investigation revealed the shutter button behaves like the camera is not cocked and the mirror can be forcibly lowered by pulling the short "mount aperture tooth" down. The DoF preview lever does nothing (as the mirror is in shooting position). That's about it. I got myself the service manual and successfully unmounted top right front and plates - I've even obtained a 1.4mm "holding" screw as the manual instructs. However, under the top right plate, there are no excessive dirt/dust particles nor loose parts in sight. At this point I'm quite scared to continue disassembling since I got no clear idea what subpart should be inspected next. The service manual doesn't seem to describe of such issue so I'm out of ideas. Do the symptoms sound familiar to anyone, please?

    I've finally figured out how to adjust the light meter (in a very croase way). The light meter itself is rotated by a pulley chain gear which is rotated by the chain link subsystem. So you have to adjust the "gearing meshing" - rotate the meter a bit without rotating the gear. Description in the service manual is a bit vague (section Exposure Meter Adjustments 2a and Fig. 3), so I made a schematic picture for anybody interested: A first roll of film has been shot today using this particular Super D body. I'm eager to see whether the repair was successful.

    Nice, I've never seen a real Contarex. I know they were known as mechanic marvels, but a nightmare to repair.

    Thanks for the suggestion. I might do this if the meter gets fixed. By the way, any suggestions how to proceed on that matter?

    John, could you, please, elaborate on the "follow the procedures in the service manual" part? The service manual contains a whole section called 'Exposure meter adjustments'. It also features a troubleshooting procedures and more. Which procedure described there you recommend as the easiest one? Currently, that particular Super D body has top and front parts removed as per the service manual. Thanks a lot

    Hello everybody, sorry for necroing this thread... I'm a bit Topcon lover myself. I got a very well preserved Super D with somehow misbehaving light meter. It underexposes the image by 2+EV (when comparing to a A7 or other Topcon bodies). First I thought it would be the battery - 1.35V vs 1.5V. Other bodies work fine with it. So this is not an issue. Mechanically the exposimeter subsystem is perfect - chain links, default ranges, etc. Alignment tests results are OK according the repair guide. In other words - the light meter needle suggests 1/125sec, f/2.8 with 100 ASA indoors. That's not correct. My last suspect is the electronic part of the light meter. Connection wires seems to be soldered OK. So maybe when a 'serial' resistor loses its rated resistance it could lead to excessive current and thus resulting in greater than expected needle deviation. Thus it might worth a try to check resistance of the resistors. Thanks
