Here you can see the internal view of the receiver when removed from its wood cabinet. Note the high components density due to the frequency modulation stage. In this receiver the components layout is very untidy.

Here the top view of the receiver. It's easy to see the AF and MF stage on the right and the power sypply on the left. The big wheel on the right is the system in order to obtain a "fluid" stations tuning while turn the tuning knob.

A detailed view of the AM ferrite aerials. These ferrite coils are mounted on a rotating disk, so during the station searching from a know outside the cabinet is possible to adjust the right antenna rotation, this in order to improve a better signal strengh.

This is the external knob used to rotate the internal AM ferrite aerials. On the knob there is a switch wich is possible activate/deactivate this function. When the indicator is placed on "0" the switch exclude the internal aerials so the receiver can operate with the external one.

In this picture you can see the strange way used to assembly the tuning scale and its indicator. Between the glass tuning scale and the tuning indicator there is a wood panel used as loudspeaker frame. All this assembly/disassembly operation require a great patience to obtain a perfect alignment between the components, otherwise the tuning indicator during the tuning movement can touch the tuning scale and scratch it. Please note the wholes on the wood frame... a lot of woodworms..... sigh.


Detailed view of the wheel used to obtain a "fluid" tuning searching while rotating the tuning knob. Unfortunatly the tuning knob is very small, so specially when in short waves it isn't easy to find a station correctly. The magic eye can help in this.

This is only a part of the complicated system developed by the Philips engineers to obtain with only two external knob several controls such as volume, tone, sensibility, band selection and tuning of this receiver.

Here in the white plastic dish you can see only a part of all the mechanics screw, frame holders, springs, whashers used in this compact but complicated receiver.
