This is the second Australian Transistor Radio from Philips and pre-dates the (now more common) 199 and 190C. The release date of December 1959 is from the manufacturers Service Data (Page 4). The tuning range of 517 -- 1622 kHz is quite large and extends beyond the modern range. The batteries are AA types and the weight is without batteries. The radio is unusual in that there is no Printed Circuit Board but rather the circuit board is punched and component leads passed through and point to point wiring finished on what would normally be called the "Copper" side of the board. The choice of the OC75 for the 2nd Audio Preamplifier shows a difference from the usual transistor selection of the period and the use of OC44/OC45s in the RF section dates it before the OC170/OC169s used in the 199C The initial advertised price (Mingay's - February 1960) was 31 Guineas. The Tuning Gang is not the sub-miniture plastic or mica insulated type but rather uses air as the dielectic element. Initially the radio was available in Red, Burgundy and Charcoal. The data sheet lists the speaker as "2 Inches" but at least one examples has a 70 mm (2.75 inch) speaker. The speaker mounts on the circuit board and has a foam gasket between it and the front grill.

Compare with the European models L1X75T or L1D90T (Fanette).
