Conar Model 224 Valve / Tube Emissions Tester

Thanks for quick response. You are correct I do need to provide more data. I will do this with photos. I have the handbook which includes a schematic. I have also removed the meter which had been savaged by the previous owner. There is no data the item at all. I hoped that someone may own or had restored one and could provide data. Working on phots and dimensions now.
Thanks
Chris
