Vintage Marshal II Power Control Unit by Meccano Ltd. Manufactured in England.It operates on a 220/250 Volt AC input and offers dual outputs: 12 Volts D.C. (8 Watts) and 15 Volts A.C. (9 V.A.).The unit features a large control knob for adjusting speed and direction (Reverse, Off, Normal) for model railways.It is designed with double insulation and typically bears a label stating "Earthing Not Required", but given its age I wouldn’t rely on that. It hasn’t been used for more than 30 years, but was working then.
