SIMPSON 1000 Vacuum Tube Tester Plate Conductance Tested & Great Price
I have replaced the grid wire with proper, flexible, rubber wire as these get brittle with age. It has the paper capacitor updated with a modern unit. Tester works fine and is in good condition.The original power cord is in great, flexible condition. Some of the covering is loose on outside, plastic windows over roll chart has yellowing. Meter face is perfectly readable but it looks to me someone tried to polish and it would need a proper polishing to be perfect. This is a fairly accurate tester of the "Plate Conductance" type. Included is a copy of the original manual.
