I said you couldn't Google. Never said you couldn't look in a radio!!

Here's the answer. Well, here is one of several variants. As you can see there is no heavy expensive power transformer. And it will run on AC or DC if you can find 115v of battery!

Many of these were repaired "while you wait" as the tech simply swapped tubes until it worked. Sometimes you could tell if a tube was "gassy" because it lit up purple. Some were intermittent and a tap with a pencil eraser would indicate that. But if you lost a filament then you could either swap tubes until you found it, or really impress your customer by locating the open filament with a meter, and fixing the little radio on the first try.
