901B PCB Restock

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



1630d BOM errors

 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.
