WIRING DIAGRAM OF MODEL 36 WITH RESISTANCE TYPE VOLUME CONTROL AND CABLE CONNECTION PANEL FOR LATER MODEL "Y" POWER UNIT. (Note that the red and the black cable leads feed the R.F. filaments as well as the 1st A.F.
filament. In some Model 36 sets the + B Ist A.F. cable lead is green with a yellow tracer.)

Receiver Chassis

Model 36

SPECIAL NOTE. The parts listed on this page are those used in the roooivor chassis. The power supply chassis was available in two productions. The diagrams of the two power supply units are shown on page 98 of Rider Manual, Volumo l. See Special page 98 for data concerning these two power packs.

These parts in receiver chassis

Note... In late " y " units show on
the following resistors are used but not shown in the schematic. The " Y " unit is the power pack for the Model 36 receiver. These parts in power unit chassis.

These units and three center tapped filament shunt resistances are contained upon the panel assembly, which is located within the metal unit. The filament shunt resistors are of 20 ohms cach, part # 9434.

Special attention is called to the fact that the r-f and.lst a filament circuit contains resistance wire in place of fixed resistors, The same is true of the detector circuit. See schematic of the early " Y " unit on

Resistor 15941 (12,500 ohms) may be marked 9424, when found in the chassis. It is to be replaced by unit # 15941.

DETECTOR AND Two STAGE AUDIO FREQUENCY AMPLIFYING CIRCUIT USED IN LATER MODEL 36,
AND IN MODELS 37, 38, 40, 42,44 AND 52

The 2nd A, F. filament shunt resistance (shown in dotted lines) is used in all Model 36 sets and in many Models 37 and 38. In later Models 37 and 88, and in Models 40, 42,44 and 52, this resistance is not used in the set, but the 2nd A.F. filament shunt resistance in the power unit is used for the same purpose a green-yellow tracer lead connecting speaker post No. 2 to the centre tap of the 2nd A.F. filament shunt resistance in the power unit. In Model 36, and in Model 37 console sets, the two terminals on either side of the ground eyelet are used for toggle switch connection in the 110 volt line. Insome Model 36 sets a green-yellow tracer lead is used instead of a black-red tracer lead for connection to the yellow lead of the 2nd A, F.T. The R.F. plate circuit resistance is not used in Model 86 nor in some 37 and 38 sets. Except for these minor variations, this circuit is standard in these sets, and the service man should remember the color scheme of A.F. transformers and the colors of cable leads and their location on the connection panel.
