[Elecraft] K3s Hearing low level rear speaker audio with SPKR+PH no and low AF set

[KK1W]

I have similar issues with K3s #10120. 

Setup:

K3s
Amplified stereo speakers connected to SPKRS jack of the KIO3B
Heil headset plugged into PHONES jack of the KIO3B
CONFIG: SPKRS = 2
CONFIG: SPKR+PH = YES

This works as expected. I have stereo audio in the headphones AND the
external speakers.

When I change CONFIG: SPKR+PH = NO I still have low level audio coming from
BOTH of the stereo speakers. Headphone volume is normal. 
The left speaker seems to be slightly louder than the right speaker.
Adjusting the BALANCE control will alter the balance of the two speakers.
There isn't any adjustment of the balance that doesn't produce some audio
from one or both of the connected speakers.

When there isn't a patch cord connected to SPKRS and the internal speaker is
opeating there is NO audio coming from the internal speaker when CONFIG:
SPKR+PH = NO. This is exactly what is expected and NOT what happens when
external speakers are connected.

Not owning an original K3 I've assumed this is just 'something I have to
live with' with the K3s. Admittedly it isn't a huge problem but there really
shouldn't be ANY output from the SPKRS jack when CONFIG: SPKR+PH = NO.

Just adding my observations to the thread,

Jim/KK1W
