 Note for older 422 Centurion amp owners: ​ Using an older Centurion with the newest Ten-Tec HF transceivers - Pegasus, Jupiter, and Orion - may require a small modification to the QSK board in older Centurion amps for proper QSK CW keying. Short diode D2 (red diode, 1N4148, next to Q1) with a jumper wire.  The current 422B does not require this modification. For questions, please consult our service department at (865) 428-0364 or via email at service@tentec.com Note for older 422 Centurion amp owners: ​ Using an older Centurion with the newest Ten-Tec HF transceivers - Pegasus, Jupiter, and Orion - may require a small modification to the QSK board in older Centurion amps for proper QSK CW keying.
