This AKG C24 is in great sounding condition. AKG has replaced the original connector in the base of the microphone with a new 12 pin connector to reduce noise and increase connector reliability. Power supply has custom pattern control modification, but it was implemented very professionally with Allen Bradley potentiometers and works great. The capsules are original and sound wonderful. I will include a new 6072 tube to replace the existing tube to guarantee performance. The system is complete and wonderful, only selling to handle tax losses from last year.
