repairing a broken delay
I had an old tokai analog delay that someone gave me that sounded great until it crapped out on me...  
 
Today I decided to try to fix it and put it into a new box, but I am running into difficulties.  
 
When it started to malfunction, basically it just passed a clean signal with no effect. To get the delay to work, I had to mash around on the case or maybe push down on the input jack -- in other words, something went screwy. I thought maybe just re-soldering the input jack would do the trick, but no luck. It powers on (I replaced the power jack and installed a new heavy duty on/off switch in place of the old one) but still only passes a clean signal. I noticed that the original on/off switch had possibly a capacitor soldered to its lugs - could that be my issue?  
 
Nothing looks broken on the top of the circuit board, and at this point I don't see any broken solder joints on the back. Only potential issue I see is a couple of holes in the top of the board that aren't bridged by a capacitor or resistor - wondering if maybe something fell out -- I hope not!!  
 
 
Can anyone point out what I might look for in trying to solve this problem?
