[Icom] HF-bands TX problems IC706MK2G

[Theo Koning]

Hello and thanks for reading this message.

I have a 706 mk2G, 
There is a problem with the HF amplifier.
When I push the PTT switch I see the 706 is making full outputpower (100 watt) for less than a half second or gives direct 2 watt outputpower, within a half second the outputpower is dropped down to 1 watt on the HF bands, mode switch gives no difference.
It looks like a bad contact somewhere or a bad diode, but we can`t  lokate it in all the smd parts

Do you have experience to solve this problem?

With best regards, Theo PB7CW / AB1DM
