[FUN_Mail] AM3100 Intracellular amplifiers

[Ashley L Juavinett]

Hello FUN colleagues —

I hope you’re taking care of yourselves right now.

I’m reaching out with a mundane request, hoping to tap into the deep electrophysiology knowledge in this group. We’ve been having repeated issues with our AM3100 Intracellular amplifiers<https://www.a-msystems.com/p-201-model-3100-intracellular-electrometer.aspx> after about ~6 years of using them. They’re either very fickle or have stopped working entirely (the immediate symptom is the DC offset does nothing, and/or Ohm test doesn’t work).

I’m writing hoping that someone has experience with AM3100 amplifiers and ideally even an idea of what’s going wrong with them or how to fix it. AD Instruments (who we purchased these from, along with PowerLabs) has not been useful.

(For what it's worth, we have some old Getting amps and we’ve been slowly replacing the AM3100’s with those, but I’m hoping to fix the AM3100s if possible.)

Thanks in advance for any insight (or even just sympathy) you can offer.

Sending lots of care from California,
Ashley
