This has been in service for years, & performed flawlessly. That ended when it was mistakenly left powered on overnight. Since that time, there's no relay output to the speakers. So begins the journey of finding out what's gone wrong. It's a tireless effort, with dashed hopes along the way. No service information available on this particular model, except for it's similar big brother the A502. SAE went out of business shortly after this unit was produced. This is from 1985. By 1987, or so SAE was no more. Good news is, the culprit seems to have been located. When it's known for certain, it will be presented in a Pt. 2., put-back/reassembly.
