Recently I have started refurbing my companies extremely neglected Hollis TDL wave solder machine. After doing a general cleaning, de-fluxing, and de-greasing I have all the mechanical components back in working order. What i am left with is the electrical panel, which appears to have been altered at some point. I'm looking for anyone who has the service manuals, including electrical schematics so I can continue. Any help would be greatly appreciated as this is my first complete refurb.
