Hi Guys,
I am trouble shooting in my IC-475 and need to find the typical operating
current in the two following transistors:
2SK125
3SK129
These are RF amps in the radio's front end. I am chasing an excessive RX
8v current drain problem that is overheating the RX 8v pass transistor in
the 8V regulator circuitry. I have measured the current in all the
branches from the RX 8v line and need to confirm the current drain in these
two transistors with what I have measured. They are not shown in any of my
spec books here. Perhaps some of our Japanese friends have access to such
information. I would appreciate any info on this.
Thanks,
Roy -- W0SL
