Lopent, Advanced A series 3.5K30W single-ended output, suitable for 300B 300A 2A3 6C4C and other electronic tube ,single-ended Price is per ONE PAIR (2pcs)
Spec.:
Power: 30W (20Hz),
Frequency response: (all are open loop without feedback, take the actual measurement data of the electronic tube )
300B end 10Hz--70KHz (+0dB, -1dB), 16Hz--45KHz (+0dB, -0.5dB)
2A3 end 12Hz--70KHz (+0dB, -1dB), 18Hz--50KHz (+0dB, -0.5dB)
Primary impedance: 2.5KΩ, 3.5KΩ, secondary: 0-4-8-16Ω,
Core size: EI96 stack thickness 50mm,
Primary copper resistance: 82.5Ω (B-P2.5), 97.5Ω (B-P3.5)
Secondary copper resistance: 0-4Ω terminal 0.24Ω, 0-8Ω terminal 0.33Ω, 0-16Ω terminal 0.67Ω
Inductance: 18H (DC bias current 80mA, 20Hz, 5Vrms, test equipment HIOKI 3522-50 LCR Meter)
Primary allowable maximum DC: 100mA (65-85mA recommended)
Each group of transformers are tested and matched, and DC current is added to the primary inductance test, which is more in line with actual working conditions.
Pairing standards:
Copper resistance deviation <1%
Primary inductance deviation <5%
