I do not wish to go to digital for several reason. I have the Lehman and 
used it for several years with a strip-chart recorder.  The cost of ink and 
paper became prohibitive and I turned it off.
    I want to find a drum recorder and have had no success in finding a 
source. Can anyone help me? I can repair it bother mechanically and 
electrically. I think the seismic labs are phasing them out and I wonder 
where they are going.
