OEP V78A01F Audio Output Transformers


V78A01F 25W valve output transformers are constructed with a grain orientated steel core. The core construction reduces distortion and reduces the stray magnetic field. Featuring 24.5% UL taps on the primary output these push-pull transformers have outputs for 4 Ω, 8 Ω and 16 Ω. V78A01F push pull transformers are suitable for use with amplifiers with EL34 valves.

UL94-HB (minimum)
Temperature class B (+130°C) minimum
19 H total primary inductance at 1 kHz
85.7 mH total secondary inductance at 1 kHz
Isolation of primary to secondary is 1 kVrms for 2 seconds
