The input should always be terminated when not in use because the [[sampling diodes]] are easily damaged by excessive inputs or static discharge. See that article for possible replacements. | *The input should always be terminated when not in use because the [[sampling diodes]] are easily damaged by excessive inputs or static discharge.

*The ground contact of R4 can become intermittent, causing the input impedance to go high or fluctuating. The cure is to disassemble the sampler incuding the sampler board covers, and then carefully bend the ground tabs of the input termination resistor outward. | |||
