KPA100 Transistor and IC DC Voltage Chart
Band=40m, DC supply voltage 14.1 VDC; Power level 11w or greater; High Current PS connected and powered on.
Important:
The voltages shown were actual measurements made on a properly working KPA100. Variations of up to 10% of the
value shown due to power supply voltage differences and component tolerances are to be expected.
