These boards will NOT solve mainframe issues eg: defective switches, defective power supply voltages, zero drift, etc, with the HP-410C. These boards are intended to replace the Hybrid A3 board , and the intermittent calibration functions defective calibration potentiometers, of the A6 board. No circuit changes necessary. We recommend the A7 voltages be checked before these boards are installed. Compatible with all HP-410C instruments, from the oldest to the newest, compatible with all three A7 board configurations. Calibration WILL be necessary after installation. A word about HP 410C Calibration. OEM, (Original) HP-410C instruments were individually calibrated: Meter scales were printed for each instrument. The chances that a HP-410C instrument still has the original meter scale are microscopic. This means the readings between Zero and top end of any given scale MAY be accurate, but probably they are not. Over the lifetime of the instrument, meter movements (they are analog) have been replaced, A3 and A6 boards have been replaced, power supply voltages have deviated, so the original calibration has long been lost.
