RCA WT110A Cardmatic Tube Tester. This is a Mutual Conductance or GM tester. Machine is in excellent condition, I'm testing a 5600 Gm 6L6GC  bogie tube in the pictures, It test Good.   Machine is easy to use, put test card in and push down to the line, pull the lever back, switch to calibrate, set to line, switch to test, testing is automatic. I also tested a 6SN7, it was easy to test, there is a P1 and a P2 position on the test switch, simply switch it from P1 to P2 to see if the tube balances or both triodes have the same GM. Comes with all test cards provided by the RCA factory.(You can make test cards to test any Vacuum tube you want, instructions are in the manual, which are available online) Tester uses transistor circuitry with high test plate voltage 170........ (20 more than a Hickok tube-based tester) Scale can be easily converted to GM Using bogie tubes. International Shipping.$150.00 International bidders please be advised, I use eBay's global shipping program, So there's no way to put a lower amount for customs, you will have to pay actual customs duty based on sale amount. USA shipping $80.00 or free local pickup in Los Angeles area. There is no manual. Because of the age of the machine and the fragile nature of tube testers in general, there is no warranty or returns on this item.
