<p>Hello Jeff, I agree with you. I am asking my question in case there is a simple solution to my problem that any people with little or no experience in camera maintenance can safely do, so that won'y need to spend 50$ or more for something I can easely do. Besides I am student and don't have a lot of money to spend, and I already spend a lot with films and development, so if I can spare some money with maintenance I would do it, and maybe later try to save a few bucks to afford a CLA. I already intended to send it to a specialist to mend the stuck ASA lock anyway, which wouldn't cost me much by the way (I've asked a specialist). But if repairing the faulty shutter speeds requires a lot of skill, then I would rather save some money to send it to be repaired than take the risk of making things worse by trying to mend it myself, or abandon the camera. It is in an overall very good condition: the exterior looks excellent (apart from a dent in the prism, but that isn't very visible and doesn't interfere with the camera's operation), the seals were replaced, and the meter seems to be working perfectly, so to me it would be very heartbreaking to leave this camera malfunctioning. </p>
