Mains Transformers for Tube Amplifiers LL2741

C-core mains transformer. The core is assembled with a small air-gap to compensate for any mains DC-unbalance. Estimated power rating 250 VA which can be increased with good cooling. Magnetic stray is extremely small if secondaries of the two coils are loaded identically.

Weight 2.5 kg

Copper resistance, no load output voltages and max recommended transformer current (rms) with primary connected to 230 V serial / 115V parallel and Sec 1 connected as above

Primary res. Serial/parallel: 7.5 W / 1.9 W
No-load impedance: 2k / 230V 0.5k / 115V
Sec 1: 16 W / 290 V 0.55 A
Sec 2: 0.1 W / 6.3V 3.1A
Sec 3: 0.1 W / 6.3V 3.1A
Sec 4: 0.1 W / 6.3 V 3.1A
Sec 5: 0.1 W / 6.3 V 3.1A

Please note! Output current from rectifier: 63% of above with capacitor input rectifier, 95% of above with choke input rectifier.
