TEK DG2020A Schematics

[Ade911]

Hi team, I have a dead DG2020A Data Generator , Ive given up with the power supply [dead] and used separate supplies , however I now have clock errors. I don't want to brick the unit its in a good state and boots OK. Has anyone got any circuit diagrams please, I have all the manuals that are online [Also circuit diagrams for pods as it didn't come with any].

Many thanks,
