I then had to add a little filler around the edges because the veneer on the cabinet had its edges slightly rounded.
I then noticed that on the front face, the lower left hand edge along the bottom was not "square" with the front of the bottom. The outer edge was forward a bit and the edge closet to the middle was back some. I removed some wood screws and using a hammer and a wood block, I broke the stiffeners loose both along the bottom and the side. I then glued and clamped the front face even along the bottom edge and reinstalled the screws. After a little wood filling and some sanding, the cabinet was ready for finishing.
I sprayed on a coat of sealer on the cabinet, grille, mask, and hatch in preparation for the grain filler.
I used Mohawk "Mahogany" grain filler #M608-4236 thinned a little with lacquer thinner. I used a credit card to apply the filler and went across the grain and again at 45 degrees to the grain. After a little bit, I used burlap and rubbed the filler across the grain. The color now is a deep chocolate brown. I did the same for the grille, mask, and hatch. This will dry overnight.
