OEP R35A03F Audio Output Transformers
R35A03F pro audio transformers from OEP have a 12 W maximum output at 50Hz. The use of grain orientated silicon steel for the core material reduces distortion and the stray magnetic field. R35A03F push-pull output transformers are 5k Ω centre tapped. These output transformers are ideal for use with ECL82 valves.
