The schematic says that the internal voltages that are more-or-less direct
from the power supply and have their own power transformer windings are
-15,
+12, +15, +43, and something up in the 300 volt range for the toobs.
I'm wondering if all the windings are gone, or if only one or two
secondary
windings have opened up, allowing for an effective fix based on an added
standard transformer with just one or two standard secondaries.
