Volunteer Day + Troubleshooting the All American 5 Class at KRE

June 16, 2012 @ 9:00 am - 2:00 pm

Volunteers at 9 AM

Class Starts 10 AM

CHRS CLASS – Troubleshooting the All American Five – Saturday, June 16th 10 AM. In this class, we will take a detailed look at the circuit of the All-American Five, the most popular radio of all time. After a brief review of the components found in the AA5, we will dissect the schematic, one function at a time, and investigate how each section contributes to the overall operation of the radio. We will find out what happens when a particular component fails, and how it affects the operation of the radio. This is the technique of troubleshooting an ailing radio. There will be in-class problem-solving breaks for the students to diagnose what kind of malfunctions of radio performance are caused by specific component failures. It is recommended that students taking the course are familiar with the basics of reading schematics and are familiar with the characteristics of electronic components: capacitors, resistors, transformers and vacuum tubes. Prerequisites: Taken and passed the CHRS self-administered safety training course. The ability to read and understand schematic diagrams. Instructor: John Staples, W6BM. There are a few slots left for this class. If you are interested. Please email Fred Meehan for more information. Your membership must be current.
