The EL3530 series was, according to my sources, the very first Philips tape recorder that was produced for the consumer market. It was dubbed the ‘Maestro Junior’ and came in either vertical (with speaker above the deck, left) or horizontal (speaker to the right of the deck) modes (see additional images). Various models were produced with sub-designations (EL350/10, /21 / 22 etc to signify minor enhancements or configurations)
The Maestro Junior wasn’t a success however, probably due to its excessive price – a
machine like this that cost about 700 guilders in 1953 (880 DM in Germany) was considered
to be total luxury. It wasn’t until the appearance of the simpler and cheaper EL3510
that there was significant interest for the domestic tape recorder in Holland.
This was a single speed (3¾ ips) and dual- track mono machine with a maximum reel size of 5″.
Valves used were:
EF40: AF microphone pre-amplifier
