Title: U87i capsule info
Post by: bits_ville on June 13, 2022, 08:46:59 PM

I bought this mic recently. It sounds fantastic, as a U87i should, but I took the head basket off, to check the condition and date and found the initials or abbreviation “hq” written on it. I have never seen this either on another U87i or pictures on any forum.

I believe the microphone was made in 1978, but I’m wondering if this indicates a technician who serviced the mic or if it was possibly reskinned. It sounds excellent so I don’t really have complaints, just very curious. 

Thanks
Robert

The capsule is period-correct for a 1978 mic, confirmed by the "8" on the diaphragm ring.

Thank you Klaus!  If you have a moment, do you know what the HQ stands for?

In addition to the manufacturing year you would have (my speculation) the name of the assembler, possibly the assembly station and batch.
