All items in this category have some problems. They may be repairable, but are not cost effective to repair due to a combination of projected repair time involved, availability of parts or lack of service information.  These items appear complete unless otherwise noted and will not be disassembled for specific parts.  Obvious item faults are described but other undetected faults may exist.  These items are sold "as is" with no warrantee or return and no further troubleshooting will be done.

For now, the "Bone yard" and "Tube" categories are exceptions to the "list all prices" policy.  Please contact for more details or a quote.
