The first thing I look @ is the output jack  on the pads. They might be 
dirty. Use some contact cleaner like DeOxit or Blue  Shower w/ a cottom swap to 
clean them. Double triggering sometimes indicates  that something is loose. Open 
your pads and check their piezo disc. It might not  be glued in place anymore. 
You may even have a detached wire that is just  resting where it was once 
soldered. When you strike a pad in this condition the  wire jumps off the piezo 
and triggers numerous times. The malfunction in the  brain is probably from a 
faulty memory backup  battery. Ni-cad batteries usually last 15 years. If  you 
got 20, consider yourself lucky. But beware. Cycling power through a worn  PCB 
mounted battery may cause it to explode and damage the board it's soldered  
to. This is something I learned the hard way w/ an SDS-7. As for your shells, 
it  sounds like you have some worn or broken plastic. Shells appear on Ebay US 
from  time to time. Senso may have a few in stock. He's a member of this
