PHILIPS L3Z74T 'TRANSISTOR ACE' (1961)

The Philips L3Z74T was manufactured by Philips Electrical Industries of N.Z. Ltd in 1961.

Very popular Philips NZ 7-transistor portable radio.

Available in several colours, tan being the most popular.

Cabinets (among other locations no doubt) were produced in Christchurch in a cabinetmakers shop in Ferry Rd - A lady who's father owned the shop recalled making the tan cabinets and covering them as an after-school job in the 60's.  Does anyone recall the shop name?

There is a similar-looking model (L3Z73T) which has a gram input (switched using the local reception button) on the back for playing records.

Several different dial designs have been noted.

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.
