=== Problem Description===
The pre-amp bandwidth is ~6MHz and this brings excess noise contribution in detector data. 
=== Change Description ===
Reduce the pre-amp bandwidth to ~1.3MHz by moving the poles on the pre-amp chain. This involves changing the following 3 capacitors. 
* Replace C74, C75 with 470pF (PN = 002205)
* Replace C76 with 68pf (PN=002206)
