This microphone was produced in the Pennsylvania facility before the KAT system was mass produced - note: this is NOT a modular mic. The mic and the power supply power on and work fine.The tube is also made in the USA by Raytheon. What's in the box.
Korby Audio tube condenser mic with a wooden case. 15+ feet of the original mic cable. I plugged the mic into a simple tube StudioV3 Art tube preamp, which was then connected to a Mytek ADC to feed into Cubase 10. I tested it with my voice to see if there are any issues, and to see the overall response and noise level. The mic behaves well, with very low noise level.
The tone can be characterized as being mid-range forward, with nice top, but relatively weak bass - suitable for very close proximity to avoid boominess of the voice. There are expected minor nicks and scratches on the mic, with a faint discoloration on the side around where the shockmount ring connects with the mic.
Both the wooden case and the power supply have a number of visible nicks and scratches. I don't have any other information regarding the mic. With new hardware or software items not described here.
