Hello,
A local Amateur friend has asked me to repair his Ten Tec Century22
CW transceiver, I have taken the PA assembly out 81229, removed the
transistors from the board and checked, it appears that 1 of the
pa transistors are faulty, there is also an IC near the driver transistors
which I would like to change as I would think this has something to do
with the Bios or ALC, they are no markings on this IC or the PA,s.
Can anyone Please help with the following,
1, Supply me with a circuit diagram, or let me know the type number
of the PA,s and IC)
2, It would also help if anyone knows the correct Drive Level to the
board assembly and the correct Driver, PA, Bios current/voltage.
Thanks for any help,
All costs met,
