The Philips BZ156U was manufactured by Philips Electrical Industries of N.Z. Ltd in 1955.
4-valve broadcast band mantle radio.
Note: Radio and Electronics show a different cabinet to that in the service document and photos - this is possibly a misprint, although it could have been released in different cabinets.
Colour options were either cream, or maroon with a cream front.
Also sold as a Mullard model 466, and similar to the previous years model, BZ146U (photos of this model show how the back panel should look)
Note: This is a series-string heater, transformerless, set which means the chassis has the possibility of being at mains voltage levels. If you don't know what you're doing then this set can be lethal. Note that the photographed model is missing its back, which is potentially very dangerous. The burnt wirewound device second from the right is a step-down resistor and it sees potentially lethal voltages as well as extreme heat. It is the authors view that sets of this nature should have the power cords removed and not be used for anything more than a decoration.
Valves (4): UCH42, UAF42, UL41, UY41
Intermediate Frequency: 455kc/s
Frequency Bands: 1
