[Elecraft] K3: Low speaker output problem

[Ralph Parker]

Hi gang:
Here's the situation - 
Headset audio level is OK, AF gain at 11 o'clock with my Sony MDR-V6es.
I get barely enough audio output from the speaker with the gain at 3 o'clock.
I have to set it full CW to hear the audio while I work around the shack.
Audio is not distorted at his setting.
Same problem with the built-in or separate speakers.
AF GAIN is set to HI.
I just did the DSP UPG to ol' 1823, and uploaded the newest firmware.
It made no difference in audio output.
This situation has existed since I first got the radio.

Here's the question - 
Anybody else notice this?
Did I miss a mod or upgrade?
Should I get out the schematic and make my own mod?
Suggestions gratefully received.
