The Philips 209U is housed in a rather neat looking Bakelite cabinet, and was made in 1946. It is an a.c/d.c mains valve radio with long, medium & short wave band reception.
It utilizes the following valves:-
UCH21, UCH21, UBL21, UY21.
It is a difficult radio to gain access to the chassis with regards to restoration. All control knobs are secured through their shafts by long metric screws. There are two drive cords, one for the pointer, the other for the tuning capacitor. The weakest link is the latter cord, it is usually found to be broken, and to gain access to it you have to remove the pointer drive cord off the drive drum, and unscrew the drum from the capacitor. The illustrations for both cords look simple enough from the service manual, but once the drum is removed from the capacitor (drum face downward) it portrays the diagram as seen via mirror image. I therefore re-drew the diagram for the capacitor drive cord by looking through a mirror, and then success!
The scale lamp is type 8095D-99 (25v @ 0.1amp m.e.s) seems to act like a fuse, as there is no shunt resistor, so the radio dies if this bulb goes o/c.
The green tubular ballast resistors can also be a problem, and the smoothing electrolytic capacitors. Also, the pitch coated capacitors should also be replaced with modern types. The resistors weren't too bad as far as tolerance changes went.
The glass dial is removable, and great care should be taken with it (quite vulnerable with regards to damage). The horizontal slats on the speaker front are also prone to damage
