I have a 6 tube Wonder-Bar Ford Radio, that does not work. Needs alot of work,I find no model no, or chassis no. on it anywhere.I need a schematic on it to get started on it.Will appreciate any and all help you can give me
Thanks

Hi Randall,
What are the tubes? If you can't find a match you may be able to find something close, a radio that uses the same tube line up.

Best Regards,

Bill Grimm

Hi Bill, sorry i did not list the tubes of the radio. They are 7Y4,7B6,7C5, 2ea 7A7, and a 7B8. hope this helps.

Here’s the service information on your radio, almost certainly a Zenith built 6MF080, 6MF780, or possibly a Detrola built 7070 (almost if not identical to the Zenith built radio). Model number should be stamped in the metal side or back of the radio.

6MF080:

6MF780

46-48 Ford automatic tuner. Good luck if you have problems with this “Rube-Goldberg” contraption!

Sams also covered these radios: Detrola 7070 in folder 45-10 (AR-1), Zenith 6MF080 in folder 10-18 (AR-1), and 6MF780 in folder 62-12 (AR-2).

One word of caution; don’t force the manual tuning gears, the pot metal bevel tuning gear is easily stripped, if not already stripped. The potmetal stop lugs on the threaded shafts in the rotary tuning mechanism will likely be frozen on the shafts. A little heat on the lugs with a soldering iron while applying WD-40 or your favorite solvent will help to loosen them up. If the bevel gear is already stripped, you may be able to carefully file new profile teeth in it and press it closer to it’s mating gear. Or, try to find a donor radio with a good (insert maniacal laughter here!) tuning gear.

Deteriorated rubber covered wiring, super compact component layout, cheap wafer loktal sockets, a tendency for open coils, and a ridiculous solenoid operated tuning mechanism---what’s not to like about these radios?

Good morning Meade,I want to thank you for all the service information you sent my way on the 6tube Wonder-Bar Zenith radio. I do appreciate it very much, this will get me started on the repair of it if it is worth the time and effort.

Thanks Again

:Hi again, i have a quick question about the station indicator. Does the radio have to be powered up to get it to change from 1# 2# 3#4#5# to M# for manual tunning?.

Yes, but------The radio push-bar operates the solenoid to pull the tuning core support to the rear of the tuner, then release it to stop on one of the small lugs on the threaded shafts. Each time the tuner operates, the mechanism rotates to a new position: 1,2,3,4, 5, or M. It is possible to operate the mechanism manually without power to the radio by pushing the tuner core support plate to the rear of the tuner. The mechanism must push back far enough to activate the ratchet device to rotate the mechanism to the next position. When operated under power with the push-bar/solenoid, the mechanism slams home rather forcefully to activate the ratchet, so take this under consideration when operating it manually. Try not to bend or break anything while manually pushing the mechanism.

Study the tuner description on the link I gave, while observing the tuner as you operate it. After awhile, it should be clear what all is going on with the various mechanical parts of the thing.

:Hi Meade,i took the information you gave me to follow on getting the station indicator to change from no. 1#2#3#4#5#M# for manually dialing the radio.It made it work super,by pushing the tuner core support plate to the rear of tuner. Before i did all of this i made sure i sprayed and lube all the mechanical parts i could see that played a part in getting this job done.I can now dial the radio when on the M# position.

Meade i want to thank you very much for the information i do appreciate it very much. It is great to know that there is people still around with the knowledge to help others.

Hi Meade,it me i have another question on the Ford Wonder Bar Radio.When i got it and started checking it out i found when i took the front face of the radio off i found two things that was not attached to anything that was loose inside the front face.They look like they may be spring like hinges for the Wonder Bar but i dont know where they go. Can you give me any help on these? would appreciate very much.
