Nick,
Something simple to check: Some CTC2 schematics incorrectly show the HO coupling cap [mounted above chassis next to the drive pot] as 0.01 uF, where the final design value is 0.0015 uF. That alone can cause an overdrive line if there's a 0.01 instead of the correct 0.0015 (or. of course, a 0.001 uF is good too).
