[Elecraft] 160 meter error

[Peter]

Hello,

Just trying to finish my K2/100 (No 4147)

The K2 with PA, NB, AF filter and ssb unit just working fine on 80 -10 meter

The 160 meter extention refuse to work.
When transmitting I get a hi current warning. The power on the output is zero.
Will get about 2 A current when power set to 2 watt, but no output

What have I observed:
I have 13.5 V when keying
On test point R30 I have 3-7V (1800/2000 Kc)
C13/14 installed and switched to ground when going to 160 (K3 switch)
Good power on 80 meter
160 current will drop when ajusting L3/L4
Will receive 160 signals.
Extra rx antanne switch works.
All components on 160 meter board are ok and no bridges
C68 and C153 are correct

Where to look next?
