GE 41, 42,43 These models appear on pages 17.1.2 through 17-16 of Rider's Volume XVII. The following changes should be made. Add Cat. No. REF - 003, line fuse F201, 3AG, 5 amp., 250 volts, to the parts list and add this to the schematic diagram of the Special Power Unit on page 17-3. The fuse should be placed in series with the power transformer primary and the power cord. Besides the addition of a fuse, the safety will be further increased by placing e sheet of asbestos underneath the power unit to cover the ventilation slots. Thus, even in the case of overload, the hot tar of the over-heated transformer is prevented from dropping on the floor.
Add Cat. No. RSV - 001, Switch-power ON - OFF switch to the parts list. Replacement is readily made by merely bending the mounting taps.
To adjust for minimum hum level, turn the volume control until the audio output is zero and vary resistor R.201 (which is parallel to the filaments and center-tapped to the chassis, forming an effective hum balancing circuit).

General Electric 41, 42, 43, 44.45 These models appear on pages 17-1,4 through 17-16 of Rider's Volume XV11. A sliding type switch has been added in series with R67 (8200 ohms) connecting the resistor to the phonograph pickup input jack, J3. This switch is on the receiver chassis back Apron with its respective label indicating High Fidelity and Normal, the open and closed positions, respectively.
In the replacement parts list under Cat. No. RSS - 003, add the item: High Fidelity. Normal switch.

General Electric 50 This model will be found on pages 16-1 through 16-4 of Rider's Volume XV. This change covers a correction to the original parts list in the model 50 where Cat. No. RHS - 001 was changed to RMX - 006 for a tuning assembly and spacer.
A further correction is necessary in the item description since only the tuning shaft and drive pulley (Assembled) supplied under RMX - 006. The spacer is the tuning shaft bearing, and is catalogued a8 & separate item under RHJ - 001. The original parts listing of the drive pulley under this number has been deleted.

GE 140 This model appears on pages 17-21 through 17-23 of Rider's Volume XVII. The following changes should be made in the parts list: From Cat. No. RAD - 027 remove the statement " (with loop connecting strips only). " Change Cat. No. RCC 075 to read RCC - 080. Delete Cat. Nos. RDK - 098, RHC - 008, and RMX - 103. Add the following parts.

The following procedure is recommended for repairing broken antenna loop connecting straps.

The broken straps should be cut back flush with the inside edge of the notch on the loop. The flexible wire is then used to make connections from the loop to the inside of the receiver. Consult the accompanying diagrams for loop connecting de. tails and wire specifications. Carefully lift the section of the loop to allow connecting the specified pieces of wire and solder

2 REQUIRED PER SET Above, the loop connecting details of the General Electric Model 140. The wire details for the antenna loop connections are shown in the lower figure.

wires to remainder of loose straps. Re move the fibre strap guide which original. ly insulated the loop straps within the cabinet. Remove original wire leads and pieces of loop strap connected inside the cabinet to the chassis terminal strip and pin 6 of the 1R5 oscillator-converter tube socket. Solder the new leads from the en. tenna loop directly to the terminal board and tube socket. Make certain that the inside of the loop is connected to pin 6 of the 1R5 tube socket.
The following procedure is recommended to replace a speaker in this model.
1 - Unsolder leads on speaker, using small tip iron.
2 - Unsolder 90.af capacitor (C14) at terminal strip.
3 - Without unsoldering, remove dual 40 uf capacitor (C20) from mounting clip.
4 - Using long screwdriver (8 inches or longer) loosen screws holding speaker to chassis.
5 - Remove nuts holding speaker to front panel.
6 - Lift up left end of resistor mounting plate and then lift out speaker,
If the antenna straps which interconnect the antenna in the receiver cover with the radio chassis circuit break, the following replacement procedure is recommended:
1 - Bend up insulating material covering set end of antenna strips by inserting the tip of a long-nose pliers and twisting gently so as not to tear material.
2 - Unsolder wires from loop strips in receiver.
3 - Remove screws holding door cover.
4 - Lift loop at point midway between hinges to expose strip rivets and un solder loop from loop strips.

5 - Remove rivet or rivets as needed, taking care not to damage loop or loop back.
6 - Replace broken straps by new members, Cat. No. RCE - 002, and rivet it in piace with eyelets, Cat. No. RHE - 003
In order to replace the rectifier disc assembly, SR, proceed as follows:
1 - Remove two mounting screws from the power switch, S1 (door switch).
2 - Dress power switch away from mounting plate, providing more access to underside of top chassis deck.
3 - Unsolder leads to rectifier disc assembly.
4 - Push aside components underneath rectifier assembly mounting screw until screw can be loosened.

General Electric 210, 211,212 These models appear on pages 18-21 Through 18-25 of Rider's Volume XVIII. Change the third column (Signal Input Point) of the alignment charts on page is 23 to read: 12BE6 grid (pin 7 of V2). See note
7.
The parts list on page 18-25 should be changed as follows: Change catalogue number UOP - 557 to VOP - 558 for Speaker 544 - inch PM. Add the reference symbol R32 to Cat. No. URD - 141 - Resistor
6.8 meg., kw., carbon.
The following changes have been made in the schematic diagram on page 18-21. Where capacitor C38 is shown terminating at ground on this schematic, later model receivers have this ground connection re. moved and the capacitor is terminated at the junction of the antenna input and capacitor C14. Capacitor C36 should be added and connected from the junction point of R29, pilot lamp I1, and pin 4 of V7 to ground. Resistor R32, which has been added to replacement parts list above, is connected from the junction of R8 and C4 (AVC filter) to the cathode, pin 2, of output tube V6.
This resistor, R32, has been added to increase the converter stage gain when operating in the A - M position because of a change in performance characteristics relative to grid cut-off of the 12BE6 tube.

General Electric 230 Kaiser - Frazer This model appears on pages 18-26 through 18-28 of Rider's Volume XVIII. The change involves & substitution of catalog numbers in the replacement parts list as follows:
Cat. No. URE - 035 and URF - 055 are catalogued for carbon-type resistors. These numbers are to be replaced for numbers specifying wirewound resistors, RRW - 037 becoming the Cat. No. for R13 and RRW. 036 the number for R18.

General Electric 502 This model appears on pages pages 17-4 through 17-8 and pages 17-89,40 through 17-47 of Rider's Volume XVII. The changes involve'a schematic correcton and a cor. rection in the value of a component in the replacement parts list.
The schematic diagram which shows an open circuit in the screen grids of the 6V6 tubes, V10 and V11, should be corrected to show the screen grids connected to the 260 - volt B - plus line.
In the listing of Cat, No. RCW - 1028, the capacitor value was mistakenly given as 22 - uf. The capacitors listed are actually 100 - vuf and RCW - 1028 should be changed to read 100 - uuf.
