The Philips F5Z37A was manufactured by Philips Electrical Industries of N.Z. Ltd in about 1967.

8-valve Hi-Z broadcast band stereogram with Philips AG1025W or BSR UA15 record changer.

7-valve equivalent, circuit uses two rectifier valves instead of one.

Year is a guess based on valve lineup and printed circuit board use.

Almost identical electrically to the F4Z37A Concorde

Also available as an F5Z67A, which uses different valves but looks identical otherwise

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.
