I had been looking everywhere for a proper service manual for this VCR. Everywhere else that has this available for download has a very light version. This is the full service manual with all aspects that would interest anyone looking for the service manual for the AIWA HV-MX100 Worldwide VHS VCR. Great quality (as always). A winner hands down. Best Quality.
