Technical
Tips from Mark W. Persons |
 |
This is a Collins-Rockwell 831D-2/Continental 814R-1 2.5 KW FM Transmitter from the mid 1970's with its back door leaning up against the left side. |
 |
As viewed from the rear, it is common to find the plastic chimney has failed above the 5CX1500A or B power amplifier tube cavity. This chimney is needed to vent hot air out of the transmitter cabinet. A suitable solution is to cut galvanized sheet metal about 3-1/2" high to create a new chimney. |
 |
Here is the completed
solution with a hose clamp to hold it in place. Not bad for 30
minutes of work.

|
The stories go on and on.
Stop in again sometime. I'll leave the soldering iron on for you.
