Doepfer

hi.
i received a doepfer a112 sampler (wavetable oscillator) module with a 
broken battery terminal that appears to have broken due to battery 
corrosion.
i just spent quite a while fussing with it and, while its monitoring 
the input signal ok, im not getting this module to sample.  
even without a battery, shouldnt samples stay in memory while power is 
on? 
i should also note that when attempting to sample into s1 or s2, i can 
hear random popping sounds when the tune control is set to above 5, 
even when theres no audio signal input.
btw, ive been sampling while gate is on and have switched back to play 
mode and attempted to gate the sample using both the manual button and 
an external gate. the most i get is a click at gate on.  
any advice would be greatly appreciated
thanks
