- Classic Octopus Tester
- Scope set to X-Y for voltage-vs-current measurement of part
- Look at scope pattern for device signature
- Out of circuit component tester
- In circuit component tester
- Test 2 units and compare signatures on scope
- Use 6.3V "filament" transformer
- 8.91V - Vpeak
- 17.82V - Vpeak-peak
- 1mA, 10mA switch
- Pot adjustments to set current (transformer variances)
- 2 BNC jacks
- Connect to XY on scope (X=CH1, Y=CH2)
- Plus, Minus Banana jacks
- AC powered
- C13 jack with switch
- Fuse
- Build into Bud Box CU-1945
