Puhpow,
It looks to me like the main filter caps are the two 8 uF caps in the dual-cap item #67. Have those have been replaced? You say the hum is not tunable, and is constant. Does the hum change when changing the volume? If so, the problem is before the volume control. If not, it is after.
Good luck.
Jon
