I've restocked with PCBs for the 901B Oscillator module, and for the Universal Daughter Board (UDB) used in the 904C PCB set.

It's come to my attention that there are a couple of errors in the BOM for the 1630d Frequency Shifter, however the schematic values are correct.
R17 and R22 are 33K
R16 and R21 are 200K
In combination with the 100k CV input resistors, these values will scale a 10V CV range (+/- 5V ) onto the 3V3 range that the Teensy ADC uses.
1630d Build Doc version 1-3 corrects this error.
