At one time you couldn’t step foot in a radio station without finding something “Marti”.
In this instance it’s a STL-10 95oMhz Studio-Transmitter link transmitter.
These units are getting up there in age, with the beige colored units like this one the oldest of the series.
Two common failures are the linear power supply (runs hot) and the nylon Berg connectors used to interconnect the modules. (they really don’t like heat). This one had both issues.
Fortunately a 13V 2.5A switching supply bolts right in. $20 fix, the unit drops ten pounds, no longer needs the nylon berg connector and runs a lot cooler.
