Icom IC-736
Headphones AF filter
Having done the modification
described here
I still felt a need to reduce level and higher tones separately
for headphones.
I inserted a low pass filter into the path to headphones. A small
PCB with the filter was created and this filter was soldered onto
JACK UNIT.

filter: |
The filter consists of
two foil condensers 4.7 uF / 50V and an inductor 1.2 mH: |
| Rezistors R1 and R2 were
removed from the JACK UNIT board: |
The new board was
coldered onto the JACK UNIT: |
