I know this thing was discontinued years ago. Ive had mine for over 20 years and other than a loose battery connection that I fixed about 10 years ago its about as bullet proof as a piece of gear could be. I know that one day that thing is going to die on me. I know I can buy another one but as far as I know there never was a successor to this thing, what can I replace it with? I have 4060s or 4061s (I forget which) that have the microdot connector.
RiotBox. It is way smaller and lighter than the MMA6000, but it doesn't have (nearly) continuous gain. Just a three position gain switch.
