K2  SN 6059 no SSB transmit
Folks, I’m trying to get a newly built SSB board working on my K2.  K2 works on CW per Don’s set up and testing last year.  I’m working through the SSB alignment on the SSB manual. Stopped on page 19 at “Fine Carrier Balance Adjustment” where it asks that I verify K2 is transmitting when PTT is pushed.  K2 is set for 5 watts power, SSB /LSB mode, SSBA is 3, SSBC is 2-1, FL1 is selected.  My wattmeter shows no output when I push PTT.  Wattmeter shows about 5 watts when I push “Tune.”  Checking for component orientation, proper component, cold solder joints, solder bridges, etc. all looked good.  Checking the DC voltage levels on the troubleshooting chart revealed some discrepancies:
On receive:
U1-U5 all pins looked ok except :
U1-6 was 5.5 v., should be 5.1 v.		U1-26 was .24 v., should be 0.0 v.
On transmit:
U1-U5 all pins looked ok except :
U1-10 was 2.8 v., should be 3.1 v.	U1-13 was 5.75 v., should be 5.9 v.
U1-14 was 5.6 V., should be 5.9 v.	U1-16 was 3.0 v., should be 5.4 v.
U1-17 was 4.1 v., should be 5.6 v.	U1-28 was 5.4 v., should be 2.4 v.
U2-8 was 3.0 v., should be 5.4 v.
All the diode voltages looked to be OK.
I am at a loss as to where to look next and what exactly to look for, and would greatly appreciate any and all comments and inputs.  Thank you for your attention.
