Vintage Synth Repair

Blah.

Actually, two hours of blah.

Following the service manual, but no success.

Anyone have some tips and tricks? It's all about tuning oscillator 2. 
It's just not stretching sharp enough up the keyboard.
The front panel Osc 2 calibration doesn't really help much. 
Internally, in order to even get close, I have to have Scaling and 
High End Compensation all the way to the left, but the upper end of 
the keyboard is still flat. No room left to stretch the pitch out more.

Osc 1 is fine.



Blah.
