Bradley,
I just got home from work. I shouldn't have gone on line this morning before going to work as I ended up rushing.
Before I forget here is a link to a Czech web site. If it works correctly for you you should see a colum of various Tesla radio model numbers.Clicking on one should give you various pictures some will include the chassis from the bottom. Although your radio is not there there is a lot of information regarding it's Czech cousins.
The link should start you off with a model 405u which I am in process of restoring.It is not my particular radio but the same model number.

There is a bottom chassis view.Also see the manual voltage adjustment switch.
