Thanks for the message.
A 10 pf at C8 did the trick. The receiver is now working properly in AGC off
mode.
Think that's at least 5 or 6 of us on the reflector have had this issue,
and this easy fix, so far. Does it deserve a builder alert on the
website yet?

Just finished alignment and test, part II of K2 #5093. All seems to be working
as it should, except for the AGC off function. This problems appears to be
the same as a few others have had, the cause of which was a bad 5.068 MHz

replacing X1 on the Control Board. You will probably find that CtrlBd-U2-1

hi elecrafters,
I received a new 5.068 Mhz Xtal and replaced the X1 on
the control board.
The Audio is not muted any more when I turn the AGC
off.
Thank you Ken K3IU, Bill WU0R, and Gary, Scott and
Brian at Elecraft service/parts.

or did just replacing X1 the first time fix the problem?
Also, what value of RP6 is installed on your control board? My RP6 is a
4.7K network.
Thanks.

jeff (K2#5210),
I only changed the crystal X1, nothing else, and that
solved the problem . The value of RP6 is also 4.7 K.

Hi Elecrafters,

I reheated the solderings on U1 C10 and D2.
Voltage on U1 pin 2 is 1.44V when agc slow or fast
