Add to the schematic, the information that the i-f. peak is 115 kc, The tube place- ment is as follows, looking towards the rear of the chassis, with the tuning knob nearest to you: To the right of the 1st i-f, transformer, the 6A7. Between the two i-f. transformers, the 6D6. To the left of the 2nd i-f. unit, the 75 demodu- lator. Immediately to the left of the speaker transformer, the 2525 and on line, but to the rear of the volume con- trol, is the 43 output tube. The i-f. transformers are accessible through the rear of the i-f. cans. The model 95 covers from 545 kc. to 1500 kc. and from 5750 kc. to 15,800 kc. The vol- tage table, which you should add to the page is as follows: Tube Plate Cathode Screen Fil. I-F Amp 115 1.5 75 6.3 Output 95 IS4 105 25. 'Vg/mga "rm-limi firm/gh plate mum.

Broad- cast band alignment trimmers for Ist detector is on side of first section of gang, nearest the front of the set. The pre-selector unit broadcast band trimmer is on the side of the middle gang and the oscillator trimmer for broadcast band is on side of third section. These trimmers are aligned at 1400 kc. The slide wire adjustment is the image supV pressor trimmer, aligned at 160 kc. for MINIMUM response. Broadcast band trimmers aligned for maximum re- sponse. Short wave trimmer, aligned at 12,000 kc., is located on rear of chassis on line with the phonograph jack. The 600 kc. oscillator trimmer is located on the front of the chassis. To adjust image suppressor, tune the receiver and the test oscillator, feeding into the antenna and ground of receiver, 1630 kilocycles. Slide the wire in or out of the pre- r selector circuit until response is MINI- MUM. Then repeat alignment of the broadcast band at 1400 kc. for maximum Airline Model 62- l 53 This Montgomery-Ward receiver is the same as Models 62-124 and 62- 129, found on page 5-5 of Ridet's Manual, With the exception of the folv A voltage regulator is incorporated on the chassis, this being mounted in the back left comer by means of a two- prong plug and a receptacle on the chassis. When no regulator unit is employed, the receptacle is covered with a piece of Fibre, which is eye- letted in place to protect the jumper When these sets are shipped with a 3-volt dry "A" battery the regulator unit is in place on the chassis and the initial voltage adjustment has already been made. If the set was originally not equipped with a regulator and it is desired to change from a 2-volt bat- tery to one of 3 volts, the regulator may be inserted by removing the Fibre covet, pulling out the jumper wire and inserting the unit by matching up the two-prong plug with the receptacle and pushing down the unit until it rests firmly in the socket. The voltage reg- ulator is connected internally in series with the plus A line. In some of these sets considerable variation in the type 19 tubes has been experienced with the result that the tone quality has been poor when this tube was operated at a bias of 6 volts. This bias has been changed, therefore, to 4,5 volts, which has been found to be satisfactory in all cases. To eHect this change, connect the white battery lead with the "06'Y market to the '-4.5 volt tap on the uC" battery. This lead and the green and yellow lead, with the volt marker, will then be connected to the same ---4.5 volt tap on the battery. Airline Models l>2l49l 62-I55. 62-l60. These Montgomery-Ward receivers are the same as those described on page 5-3 of Rider`s Manuals (Models v62- 120, 62-122, 62-126 and 62-128) with the same exceptions as those noted elsewhere for Airline Model 62-155. Starting with serial number 11501 the following changes have been made in the receiver, whose schematic dia- gram is shown on Belmont page 2-1 of Ridet's Specialized Auto Radio Manual, Volume II: The cathode and the suppressor grid of the 6D6 tube are now connected to _R-B, R-S and C-S and so to the cathode of the 6A7 tube, instead of to C-1 and R-2. These last mentioned parts are now out of the circuit. The value of R-6 has been changed to 19,000 ohms from 12,000 ohms and R-Il from 250,000 ohms to 500,000 The alignment data for the Philco 802, the schematic of which will be found on Philco page 2-57 of Ridet's v Specialized Auto Radio Manual, Vol- ume II, is the same as the alignment data for Model SOO-Code 12?, which may be found on Philco page 2-56 of the same volume. Run No. 2, Condenser, No. 52 (50 mmf.) removed and Part No. 30-1032 (250 mmf.) added. Filter choke, Part N0. 32-1374 added, being connected in series between pilot lamp, No. 51, and resistor No. 53 and condenser N0. 52. The original Model 12 was similar to the Model 8, shown on Philco page 3-5 and page 1599 in the Radiotron Complete Manual, and was properly known as Model 12-Code 121. The later Model 12 is the Model 12-Code 122 and is similar to Model 9, except that it is for 12-volt operation. The tubes, circuit and base arrangement are the same, but the tube heater circuit is that shown in the accompanying illus- tration. Since 6.5-volt tubes are used,7. Detox IF 20d' PYAF 0-!!

a series multiple connection must be
used to operate them from a 12-volt

The shunt resistor on the oscillator
tube is Part No, 33-3002 and is 21
ohms. The speaker employed is the

used, supplying 40 milliamperes at 220

The Model 12 has been designed
especially for bus and boat installations,
