FT1000/d Help Request
 

Hello OMs:

I am seeking some help from owners of FT1000(D) owners.

Please contact me if you are willing to provide me some resistance
measurements around the PS (voltage regulator) Unit pcb. I need about
12 reference measurements to be made. Requires use of ohmmeter and
removal of the radio's top cover.

eMail:

I have just replaced the bridge diode rectifier ( D9301) used for the
regulated 30 volt section of the power supply. It is a $20.00 item
from YAESU that I do not want to function as a fuse ! The resistance
measurements are needed as a comparative reference before I power on
the radio. If your measurements vary greatly from what I show here,
then I must look deeper. Would appreciate help very much.

Thanks es 73,

Hello Vince,
am surprised the diode bridge was taken out - there must be a dead
short AFTER it - have you checked the pass transistors - btw, send me
a circuit and I will try to fault find. What does it feed?
