Canon A1 shutter release delay

Question

My cabon A1 shutter release delays for several seconds under normal light and in all modes. I know this is probably a physical fault because it started directly after the camera fell onto the floor one day. My question is; is is likely to be easily and cheaply repairable. I have seen similar bodies for sale on ebay at very reasonable prices but the thought of chucking away what was once such a lovely piece of kit makes me cringe. (I am a hoarder, I know!)
