VR1        100K x2 ALPS RK168    688-RK16812MG099     8.00



1) Sub these from Mouser:
Code: Select all
C5,C6,C8   47uF 35V, 5D 2LS      647-UVZ1V470MDD      0.17
R1,R2      210, 1/4W             271-210-RC           0.13
VR4        10K Pot               72-T93YB-10K         1.58

647-UVZ1H470MED qty 3
271-215-RC qty 2
72-T93YB-5K qty 1


2) Wait for backorder from Mouser (less than two week wait):
Code: Select all
RL8        Omron G5NB 24V SPST   653-G5NB-1A-DC24     1.92
SW1-SW4    Pushbutton switch     10KB012              1.35


3) Sub from eBay:
Code: Select all
VR1        100K x2 ALPS RK168    688-RK16812MG099     8.00

Mouser has had nice stocks of this fantastic part several times but sells out quickly. eBay is probably the fastest route to go.
eBay link to 100K 2X ALPS RK168

Be sure to get the 2x dual gang (stereo) 100K. It has a single row of eight pins. It also has the black plastic connector on the rear for PCB power pins.
