I purchased this unit in the early 90's and was my first real service monitor. Over time the unit quit and after searching found there was no service material available. 5 years after giving I ran into some schematics on the unit. After all these years I am starting to learn my way around it and will be posting a series of repair vids on it.

Com Ser Labs have been long out of business. They were located in Florida. It is believed they were formally Lampkin Laboratory. Which also disappeared in the 70's.

Nice! Thanks for sharing...it's a pretty cool video.

Thanks Moleculo,
I only started doing videos about a year ago. I will be doing many more in the near future. Covering Reviews, tear downs, repairs and tutorials. Just trying for now to get better at doing them.

The reason for doing this video is to get some information stiring. Not much out there on this unit. But I know there were quite a few of these built.

Thanks for looking.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
