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
