About two weeks ago I posted an article that
I snipped from mods.dk about the 706mkIIg finals
being obsolete. I did some investigating and
determined that the Icom is replacing the SRFJ7044
power FET with the RD70HVF, the same power FET that's
used in the Icom IC-2720 dual band. If you check the
product reviews in eHam.net under;
Transceivers: VHF/UHF Base/Mobile (non hand-held)/
You will see several complaints about finals burning
out in the IC-2720.
I hope that Icom isn't using the same finals in the
IC706MKIIG that are causing problems in 2720!!
Here a repeat of the article.
The 706MKIIG radio has 2 different versions of the PA
board. The older PA board's finals (1590002690)aka
(srfj7044) are no longer available and would require
replacement of the PA board. The newer style PA board
transistors are part# 1560001190 (rd70HVF) and can be
ordered by The 2 styles of transistors are not
The complete PA board is part# 98413600 and sells for
apx $442. The catch 22 is that this board is the old
style board, with the old transistors. We do not have
the new style boards available yet so, if the finals
fail again, it's another board replacement.
