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
