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)
