Adjust the values for R20 and R21 to correspond more adequately with the VCO Tuning Voltage Limits and the input power you get at the LM-358 (IC9).
The formula for the OP AMP in NonInverting Step Up Mode:
Vout = Vin*((Rf/Ri)+1)
Example:
For the ROS 1200
3.3V((30kohm/10kohm)+1) = 13.2V
Corrected:
3.3V((47.7/10)+1) = 19V ( max Vtune for ROS 1300 = 20V)
For the ROS2700-1819+:
3.3((64.9/10)+1) = 24.717V (Max Vtune for ROS 2700 is 25V)

nice info Lcstyle, many thanks for extra info.

you get your WB2010 finished? I'd love to see a pic of how you fixed the missing trace (as I'm coming to that point soon :))

Don't thank me.
Thank Limor Fried for giving us a project interesting enough to motivate us to want to learn stuff.
She deserves the success she's created for herself.

Very True. Building this thing has been a journey to say the least. :)
I only started electronics last December and have learned so much since then.

Today i learned something you might be interested in...

...check out my traces:

I set my iron to 450C and ran it over the traces.
The high temp melted the soldermask! Happy Days...

... kinda, the trace in the middle connects to ground, i had to trim a little to make it work right
