Old Tube Amp causing fregeuncy drift on SSB??

Wait... you rebuilt the power supply using "Beefed up" components, and also the board was putting out more.... more what? Voltage? If so how much and how did you correct this? More amperage? Of so, who cares? Earlier, not to sound disrespectful you asked me what RF bypassing was. Can you share with me what was done? I am definitely leaning toward power supply now. Although, this could be verified by just checking different voltage feeds in the radio on the board making sure they don't fluctuate.

Checks on the main board show about 15VDC in RX. With full modulation on SSB drops to 13.8-14.
 
Ok, need help on this! I decided to do some rebuilding/updating on parts in this amp.
There are 4 big filter caps (450v/320uf) in here. I unscrewed them and removed them before I took note of the +/- alignment.
2 are chained together and the other 2 are chained together.
Can someone take a look at the schematic here and tell me how the polarities need to be done. At $30 each I don't want to do this wrong...
thanks!

    Incoming Region Produces X3 Solar Flare
    May 15, 2024 @ 14:55 UTC
    Another major solar flare, but this time from an active region just beginning to turn into view off the east limb. It is possible that the group responsible is old AR 3654 from the previous rotation. The latest flare, an X2.99 event just peaked at 14:38 UTC (May 15). Stay tuned
