| Most years are best guesses, but the order is certain. |
The Pionier
series of radio kits predate all other electronic
kits from Philips. They are certainly from before 1963, possibly as early
as from 1957. The larger senior
series are based on vacuum tubes,
and the assembly requires soldering. The smaller junior
series on
the other hand is based on early germanium transistors (OC 13 and OC 14,
apparently OC 71 and OC 72s that failed quality control!) and components
are mounted with a nut and bolt system. This seems to be the ultimate
ancestor of the EE kits, as well as the later radio kits, which were also
influenced by the development in the EE kits.
I have only seen this series in Dutch

The Pionier junior
series developed in three stages:
At first it consisted only of a single two-transistor and crystal
earphone kit simply called Philips Pionier Junior
transistor-radio
This was renamed Pionier II
when a smaller diode receiver kit
and an intermediate expansion was added
Later, these two kits were slightly revised, and another expansion was added, containing a third transistor, a loudspeaker and a larger cabinet to house it
There never was a single kit with the largest construction; one had to
buy Pionier II and the II A
expansion with the Pionier III
manual, the loudspeaker and a third transistor.
Pionier - Early version of Pionier II
Pionier I - Diode receiver without amplification
Pionier IA - Expansion from Pionier I to Pionier II
Pionier II - Two-transistor receiver
Pionier IIA - Expansion from Pionier II to a three-transistor radio
with loudspeaker

Pionier S 101 - Single stage receiver
Pionier S 101 A - Expansion from S 101 to S 102 (two stage receiver)
Pionier S 102 A - Expansion from S 102 to S 103 (super
receiver)
Pionier S 113 - Super
receiver
Pionier S 20 V - Power supply for any of the receivers
Pionier S 201 - ½ W amplifier for any of the receivers
Pionier S 202 - 2 W amplifier for any of the receivers
There were no S 102 or S 103 kits, one had to buy S 101 and the expansion(s) for these constructions. S 113 is a slightly improved version of S 103 suggested if the radio is not built stage by stage.
