High-end 15-valve plus magic eye, Hi-Z Stereogram with reverb. ('Revebeogram').

The Philips F9Z06A is part of the Philips Festival Hall series of radios.

The Festival Hall series were high-end multi-band radiograms typically using Hi-Z speakers and typically complex (Philips were the Google of their day) circuitry.  They were well-built and had great sound.  The first few models were mono and valve based, with later sets becoming stereo and also switching to transistors as those became available.  There were also valve hybrids with transistor preamp modules in the record input.

The radios in this series are:

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.
