Many thanks Jerry! It was a bit hard to read, that's why I wanna make sure I measured the right points. I will measure the non-functioning state tomorrow at about the same time and send you the

This seems correct. What about when the mic doen't work?

Here you will find the results (mic working state): A=5.04 B=7.64 C=1.16 D=0.55 E=7.50 F=15.36

Can you read the voltages on the various points?

I uploaded a NT1-a PCB photo in much better quality ( /g/MicBuilders/files/Heinz_Files/NT1-a_Maesurement_Result_001.JPG ) to the Heinz_Files folder.

Hi Jerry. I measured various voltages on the circuit board in the working state (with reference to ground) but I'm sure I missed some. Can you circle the points on the circuit board that I missed? *I

Having a spare capsule around is handy. A K47 copy isn’t acoustically like the original capsule, but it will work with the R?de flat-response circuit and is a popular upgrade. Edge terminated

I have no experience with the NT1A and the proposed capsule. So I cannot be of any help here. I would guess that screw hole locations and maybe capsule thickness are items to check before purchasing

Hi Jan & James Many thanks for your suggestions! I threw it into the washing machine again and am now letting it dry. The coin laundry's nearby also have very effective shoe dryers.? Should I try

"Quick test showed high signal on lowest setting in DR-70D, knob on "twelve o'clock". Plenty gain left to use." Hmmm.... Got me thinking that the signal might be too hot for a train...

Can't complain. I just put together an OPIC ( https://opic.jp137.com/index-ldc.html ) circuit (in a BM800 body)? and connected one of these: Works like a charm. Quick test showed high signal on

From an earlier post, where you measured the voltages around the capsule during working and non working periods, there seemed nothing wrong. That would have been the area where I'd expect moisture to

I somehow have a bad feeling about the capsule connection. The red one in particular seems old, brittle and slightly bent. I checked the cable for breaks with the DMM, but unfortunately could not find

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

Nice options, but much lower output than a standard piezo disc. Cancsooundok however. Op za 2 nov 2024 10:12 schreef pmfalcman via groups.io <pmfalcman= [email protected]>:

Please keep this on the forum, Henry & Heinz.? This whodunnit story is becoming curiouser & and curiouser. My $0.02 is simply that if it is the capsule, it will be VERY noisy long before it stops

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

Hi Henry. Thank you for your detailed answer! You pointed it out very clear that my meter can’t measure the voltage across the capsule with any accuracy and why. Many thanks! The meter is like an
