The Philips B2Z56U was manufactured by Philips Electrical Industries of N.Z. Ltd in about 1965.

4-valve broadcast band mantle radio

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.  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.

General Construction Notes for Philips Electrical Industries of N.Z. Ltd:

Model codes are explained on the Philips brand page.  Philips early-mid century were probably the Google of their time - they had branches in many countries and a global brand that everyone knew - and were apparently happy to let engineers come up with new ideas and implement them.  Construction is often overly complex but very well engineered - although repairs can also take a complex path.  They used time-in-motion studies to find the most cost effective way to asemble sets and sometimes this means repairs can be nightmarish (if you've ever worked on a V7A Theaterette this will be all too aparent).  U suffix model numbers are transformerless (hot chassis) sets and great care should be taken, or the sets avoided altogether.
