If soldering small items is a problem try fixing it while solder the first pin.
There are some slightly different HAA15-0.8-A Power supply out there. Mine is different from this: http://www.cs80.com/crowbx/psmod.html
Mine has a slightly different layout. I used two 2k2 Ohm resistors. parallel to R52 and R79.
The Voltage is now adjustable between 8- and 20Volts.
So no Problem to justify for 19Volts.
- Voice Card BOM Typo:
correct: Optional: for compliance with Oberheim ECO for PW trimming on VCOs, change R73/R74 to 46.4K 1% and R15/R16 to 34.8K 1%
- IC3 (CD4011) is lacking in the BOM
You have to solder a diode at the output of the 15V regulators

Hint for calibrate the Voicecards:
The IC1 and IC4 must not be inserted while doing the calibration, because the DMM- OHMs measurement injects to much voltage which falsify the measure.
Hopefully the Green Lines shows where the Testpoints are
The both multiturn pots must be adjusted to 61K.
