For Auction:: HP 410C VTVM Solid state upgrade ( Original HP) A3 PC board. This is the A3 Solid State PC board that HP developed for the HP-410C VTVM, as a "drop in" to replace the original Hybrid A3 board. Board has been tested and repaired . This Solid State A3 PC board requires no other modifications to the HP 410C. It is totally "drop in" to replace the original Hybrid A3 PC Board. *** Calibration of the HP 410C is recommended after completion of the SS A3 board installation. Installation of this A3 board will NOT fix power supply or other existing operational conditions. The board does require that the A7 ( Power Supply) board be in tip top condition. We recommend replacing all of the existing resistors and diodes on the A7 board and check for correct voltages BEFORE plugging the Solid State A3 board into its socket. If the Power Supply filter capacitors are defective, we recommend you consider our HP-410C Solid State Upgrade Kit which contains re-stuffed filter capacitors. We also recommend the "slip on" circuit connectors to the A7 board be removed and circuit wiring soldered directly to the existing pads. ( The "slip on" A7 board circuit connectors were a never ending source of intermittent issues). All sales are final, no warranties or guarantees are expressed or implied.
