Parts

Tayda
BC857 1 PNP, sot23-3

1N400x or S1JL 

1N400x (x = 1, 2, 3. 4) Power diodes are for Reverse voltage protection - Mouser

Part No: 821-S1JL. Any similar rectifier with at least 1A rating should be okay,

such as 1N4001, 1N4002, 1N4004. Get these sizes; SOD-123 or sub-SMA (DO-214 is

too big, so avoid)

LM13700 2 SOIC

TL072 x 4 SOIC Tayda: A-1136

LL4148 diodes 4 SOD-80 Mouser Part No: 512-LL4148

BCM857DS 1 PNP, SOT23-6 or SOT457 Mouser: 771-BCM857DS-T/R

Mount the 1k tempco resistor over the BCM857 so they are in contact (1kT on

PCB). Once the VCO is tested and working, add a little heatsink paste so they

are thermally in sync (!). If you don’t care about 1V/oct tracking just use a

regular 1k resistor.
