And it begins

Alan brought over the subject radio the other day and we took the cover off to check out the guts and to cogitate about the control head interface.

Here are some pictures of the VW that the radio will go into. The plan is to mount the control head on the steering column and the box under the front hood.









I have checked the rotation direction of the tuning knob/dial and the tuner in the box. They all rotate correctly, dial rotates to higher frequency while the tuner slugs pull out of the coils.


Dial light is has the wrong holder.



Original speaker was swapped out with this one. The original holes were used to mount it and oddly the replacement speaker is a field coil type. I would have thought that a replacement speaker would be a PM type. Maybe it was swapped out before PM speakers became available...


Serial number. Looks like it was masked off and then the box painted...


Connection interface. One is power and the other the dial light. The three in the middle are blank.



End user wants 12 volt negative ground. To do the conversion all the tubes need to be replaced with 12 volt versions and the power transformer primary rewound.


Speaker removed, one can see the original footprint of the original speaker.


Speaker has a warped cone so that the voice coil is rubbing. If this guy is to be used it will need a recone. End user wants to mount the box in the front compartment so a remote speaker connection is needed.




Speaker footprint.


Tuning/volume control cable interface. 8 spline.



I added a release agent inside the splined area and injected RTV to make a mold so that new control cable end can be made.


Control cable dimensions.


Chassis screws, fancy versions. Three types, slotted/pointed, pointed, and blunted.



Small crack found in the speaker bezel.
