The Micro-100 was manufactured between September 1996 and February 2005. The following repair sheets are designed to help repair technicians and qualified owners repair and maintain the Micro-100. If at any time you have a question, need a part, or want additional information please contact us -- contact information can be found on this page at the bottom as well as most pages of our web site.

IMPORTANT NOTICE REGARDING M-100 POWER TRANSFORMERS:  The original custom made transformers for the Micro-100 are no longer available. Defective transformers can be replaced using two off the shelf transformers to replace the one original transformer -- we do stock the replacement transformers. Because of this, changing a defective power transformer is more involved than would normally be the case. Unless you, or the person doing the repairs, is an experienced electronics technician, we recommend sending M-100's to our shop for the transformer conversion. Please feel free to telephone and go over your options and we can explain in detail what is involved in doing the conversion to the replacement transformers.
