What a lovely old meter! Japanese? As used by technicians during WW2? It's essentially a 1mA meter with series resistors selected by the voltage range switch, so that at the full scale voltage, 1mA of current flows thru the meter. As a result, it doesn't have a fixed input resistance like a modern digital meter. It has a sensitivity of 1000 ohms per volt.
Hi Henry
?
That's what I was interested in. Whether the meter behaves like a digital one in terms of input resistance or not. Many thanks!
I opened it carefully and took another two screenshots from inside. It looks more like the inside of an old clock or a kind of Antikythera mechanism from ancient Greek. :-) There is a small compartment at the top which means "Shunt" 1MA200MV (1Milliampere,200Millivolt)? I didn't open it yet. The meter is Japanese.?

Regarding the NT1-a I got an answer from Rode. They suspect that the issue is moisture and humidity related and would like me to store the microphone with a silica packet in a cool, dry place for 24 hours, to dry up the capsule and resolve the issue. To investigate further, they asked me to provide an audio or video sample demonstrating the issue. I will provide the information they requested until next Wednesday.?
Additionally, the following note was added:
It's also important to note that seeing as you've purchased your microphone second hand, it unfortunately not covered under warranty, this means that any potential repairs will be up to the discretion of your local distributor.? For now, I would recommend running through the above steps to see if they resolve the issue and then once we hear back from you we can proceed down that route if required.

Let's see what Rode suggests. I'll keep you up-to-date. Should I point them to this thread? Or better not?

Anyway. I find it more interesting to modify it myself than sending it in. Or if the capsule turns out to be the culprit, buy a capsule from Matt or Jules. We'll see.
