325V 50VA toroidal tube preamp transformer guitar amp
Load Test Result: TEST CONDITION: Input 115VAC 60Hz to the primary coil (parallel both coils), 500 ohm 250W resistors as dummy load and room temperature at 25 degree C. Temperature rises 10 degree C after an hour test at load test #3.
1. Primary I = 0.01A, Secondary V = 335VAC at 0.0A, Power = 0 Watt
2. Primary I = 0.30A, Secondary V = 315VAC at 0.10A, Power = 32 Watt
3. Primary I = 0.42A, Secondary V = 286VAC at 0.14A, Power = 40 Watt
Dimension 3.5 Diameter x 1.5 High.
