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.
