ALC Problem

Pasquale S


Hi guys

I’m repairing an IC-7000, I put 2 new finals RD70HHF1 and I set bias 100% (1 A for each final)

But I have a strange behaviour ; the power goes up slowly, for example if I set 100 watt , power is 20 watt then goes up until 100 watt; same thing if I set 50 or 70 watt for example.

I change the cable, I use now one without fuses. I have done adjustment 3 times, no effect.  In VHF / UHF my 7000 is perfect, no trouble.


Any ideas ?


Thanks in advance
