Hi Guru,
Glad you got your IC706-2G sorted. I was going to suggest a longer reach 3.5mm plug. Sadly there are two different standards. Until you mentioned it I too had forgotten all about the switch under the head. I must have put mine in the ‘phones’ position 20 years ago and forgotten about it. I get both ears and the speaker is OK when the plug’s pulled. I have made a note of your post and put it away with the 706 info,
73, John.
