REALLY sorry guys , when I opened the box , it turned out to be a complete set of FLUKE 382A voltage standard spare parts kit. NOT A FLUKE 732A !! I had a number of Fluke voltage standards, turns out the 382a has a separate oven controlled 6.2 volt standard ( not a PCB ) however it uses a pcb that is the oven proportional temp. controller. I also have an Fluke 335A voltage standard card that is an operational spare , this is fully self-contained operational PCB , about the same voltage ( 6.1xxxxx) but an older Rev. version. The newest Fluke 335D uses a quarter diameter size standard with a solid state heater built into the module. SO... the Fluke 382a Parts and PCBs and voltage standard are all going the hamfest next month, but willing to sell individual parts/PCB. The PCBs sell for $15 at the Hamfest , voltage standard $35. Willing to negotiate if someone wants more than one 382a part , all assemblies are available , meter , Calvin Varley divider assembly , and transformers ( but they are real heavy { double shielded } ) Sorry about the incorrect part number . not a 732a.
