Well I am glad your machine is back in its home again. I am sure you are having a blast making sure the repairman didn't fiddle to much with the dials and settings. I would caution you to use a surge protector or better yet unplug your machine. I don't know about your area; however, here in the Shandoah Valley of VA we seem to have more brown to black outs then I ever had living in the Lehigh Valley of PA for 18 years. This just might save your machine from future trips to such a nice repair man.
