BBD Component Substitution List

Hello All,
Here is a list of substitute parts for the impossible to obtain parts for the Delay pedals.  These are all available from Small Bear Electronics and would require minimal reconfiguration of the circuits.  Let me know what you all think and then I can order the amount of parts that we would need.  Should be about $20 a person to purchase the components that we can't raid from the school supply (resistors, capacitors, op-amps, etc). 

BL3208 (direct substitute for the MN3208 which is a 2048 stage BBD driver)

BL3102 (direct substitute for the MN3102 which is a BBD Clock source)

We will need to use two of the 3208s to simulate an MN3205 or MN3005 which is a 4096 stage BBD.  There is a diagram for this type of configuration on the small bear electronics website.

  1. I have ordered enough parts of each of us to make two delay pedals. They should arrive by week 4. It will be $20 each. I will bring the parts with me when they arrive.
