I have a factory model LCR62-418Z radio phonograf combo . i wold like to find schmatic and a little abuut it . there no speaker on it and if remember there was maching transformer of sonkinde in the line to speaker but that's missing to if you could provide info on this i would appreciate it.

Hello Serge,
A schematic for your Airline model 62-418 is available here on NostalgiaAir. From the home page, enter the "Riders Online" section, then click on "Montgomery Ward", then click on your model number "62-418". You can then click on the schematic itself to see a larger view.

Your radio/phono originally used a field-coil (electrodynamic) speaker, with the field coil also serving as the filter choke in the power supply. DC resistance of this field coil is noted on the schematic as 1000 ohms. If you substitute a permanent-magnet speaker, you will need to add either a choke coil or a resistor in the power supply circuit to take the place of the original field coil. If you use a resistor, you may also need to increase the size of the original electrolytic filter capacitors in order to provide adequate filtering. The transformer you mention would have been the audio output transformer, which was commonly mounted on the frame of the speaker. You will also need to replace this with a new output transformer, either mounted on the new speaker or on the chassis if space permits. The impedance of the primary and secondary of this transformer will have to be chosen to match the 6F6 power output tube to the impedance of your new speaker.

the schematic 62-418 has 8 tubes and my radio has only 6 tubes so it dont match. the tube layout sheet says 6 tube-2 band ac operated superheterodyne radio-phonograph combination . model L379 Factory model LCR62-418Z votage 117v ac frequency 60 cycle only. and i remember the speaker was a 12 in permanent-magnet speaker because i used it on a elctrique guitar amp lost the transformer so if there is more info you can provide i will apreciate it verry mutch

yours
