Repairability of SD-24, SD-30 & SD-32 sampling heads

Reginald Beardsley
 

Has anyone attempted to repair one? If so, what was the outcome? I'm familiar with the EPROM failure repair. I'm really asking about the input and output sections as they are ESD sensitive.

Are suitable parts available? I realize that there are no schematics or other information.

Have Fun!
