Oscilloscope Power Supply Repair Solution — Tektronix G35SB080 | P/N 671-5612-06 | Power Supply Control Series
Where This Product Is Used
The Tektronix G35SB080 Control Board (P/N 671-5612-06) is a factory-original power supply control PCB designed for use inside Tektronix oscilloscopes and bench-top test instruments. It is most commonly required in the following application scenarios:
- Oscilloscope bench repair depots — replacing failed power regulation boards in Tektronix instruments to restore full measurement capability
- University and R&D lab maintenance — keeping critical test equipment operational without full instrument replacement
- Industrial calibration facilities — maintaining certified Tektronix oscilloscopes used in production-line verification and EMC testing
- Military & aerospace MRO — sourcing OEM-equivalent control boards for long-lifecycle instrument sustainment programs
- Electronics manufacturing (EMS/ODM) — restoring in-house test equipment to minimize production downtime

Why Engineers Specify This Model
- OEM part number match — P/N 671-5612-06 is the exact Tektronix factory reference, ensuring drop-in compatibility without re-qualification
- Avoids full instrument write-off — replacing this board at component level is significantly more cost-effective than scrapping a functional oscilloscope chassis
- Preserves calibration traceability — restoring the original power supply board maintains the instrument’s calibration history and certification chain
- Reduces lead time vs. new instrument — critical for labs with tight uptime SLAs where waiting for a new oscilloscope is not acceptable
- Trusted Tektronix heritage — Tektronix is the global benchmark for precision test & measurement; OEM boards carry the same design tolerances as the original build
