142 GTL Good AM Carrier Weak Modulation????

Weak AM modulation at 50% on Palomar PW-5000 meter. SSB has low forward swing with low modulation?? I have checked many voltages in the past and all that I have checked seems normal. Using SAM's Photofact. Re-align transmitter as per Sams with 2-tone audio generator and still low modulation. Replaced Audio IC TA 7222P no change. Any Ideas???
