Hi Bob,Originally posted by Bob Nickles:
If any one has a manual for this machine or a list of parsts spec. I would be willing to pay a fee for a copy. I found an old machine but the rheostat does not work.
I don't mean to be cruel, but these things are so simple that you shouldn't need a published schematic to find your way around in one. The rheostat is a wire wound unit, it is rare for them to burn out. Sometimes, the wiper contact will wear so much that it will nolonger make good contact. This is easily determined by inspection. The rheostat's value is usually clearly written somewhere on the body of the unit.
Get out your cheap DVM, start measuring things, and sketch out a schematic of your unit. It shouldn't take you more than an hour. You will figure it out. If you don't think you are up to the task, you should find someone with more experience, and pay them to do it for you. These machines were made before danger and litigation were constantly on the minds of producers of consumer devices.
