D201A low power SSB modulation

[Crambone]

Radio is working perfectly as receive is very, very strong on all Bands and Channels. On AM I dead key 4.2 watts and swing 28 but on SSB I’m only seeing 10 watts. I went through the ALC c tuning procedure in the manual and I’m not getting any adjustment on R719, R719 sees 97 vdc on leg from R720, on center leg I can adjust from 0 - 97 vdc I set it to 55vdc for now and ground on other leg. I get no power or modulation increase at all stays the same.
On the yellow wire coming from the band switch I see 0vdc rec and upto -90vdc on TX with modulation on both LSB & USB?

Where to check?
