I'm pretty sure it is stock with no mods done at all. Just went over the two ADA Depot noise mods (v1 & v2) and couldn't identify any of the mods on my MP1. This unit is from 1988 and marked as revision D (it also has the 1.38 software)

Can you tell if it's had the noise mod done to it?

Hello Kaz and the ADA MP-1 mailing list!

I have recently acquired a used ADA MP-1. The unit is rather noisy and it has a faulty front input plug. These issue led to hours of research and discovery, including finding out about this mailing list and Mr. Kylheku (among other leading figures in the mp1 technical community)

** I'd love it if someone could help me debug and locate the source of the issue **

I have also put together a list of information and mods/upgrades/refurbishing instructions and other technical resources for the ADA MP-1:, feel free to check it out
