[TechAssist] CTC177-no tuning voltage from PLL IC


Hello all,
Hope everybody had a great Thanksgiving day.
The pll transistor has 30 volts on the collector no matter what channel I 
select. The band switch works perfect, I can put a pot from the col to the 
gnd and get all channels on every band. I changed the PLL IC & crystal, the 
mixer IC, the eeprom & micro, resoldered the tuner, checked the voltages at 
all the ic pins, checked the diodes and resistors in the feedback circuit 
and no luck.The clock and data lines must be ok because the PLL IC is 
switching bands.Could I have another bad PLL IC?, or has anybody seen some 
other part here?
Thanks,
