A&H Packstoves in Tustin, CA has spares for these stoves.
I am certain they have them for the alcohol stoves, and am thinking they also had stuff for the electrics.
FYI - my electric stove still looks and works great - did you know that the r/h burner is 1000W and the l/h is 500W? Now you do. (so if you really want to heat something up - use the r/h one)
