    A Bit Of my history:  I have restored several radios including a 650.  I used Citri-Strip and a small brass brush.  Careful sanding, staining, and lacquer finish.  Veneer repairs and all.  Nice to the touch and looked like new.  I've never used wood filler, I don't understand what it does.

I recently acquired a new project. The finish on the 620 is thick, crackling, rough,and dark.  I applied a spot of citri-Strip on the front and was rewarded with beautiful  bare wood and inlay result.  I used some alcohol on another spot (right side) and was rewarded with the same beautiful result but with what looks like the original finish still underneath.   Smooth as glass, better than anything I've redone. 

Now my question:  Is filler whats needed to make the difference? I always thought of filler as something to fill in gaps and chips.
