150W 100V Line 4-16 Ohm Audio Toroidal Transformer

High power toroidal transformer for audio use. Input and output windings can be reversed or be configured differently i.e. Input windings series connected for 100V and output windings paralleled for 4 Ohm.

Primaries:
For 100V line use, connect in series, ie. join pink & yellow. Use purple & brown.

Secondaries:
For 16 Ohm use, connect in series, ie. join black & blue. Use red & orange.
For 4 Ohm use, connect in parallel, ie. join orange & black and use blue & red.
