The original amp components are a 1950’s era Supro 5w amp with an odd 10?x6? Oval speaker.  After doing some research, this speaker size seems to be really rare, and only a handful of Supro amps were made with this speaker.  With the rare size speaker, I accented it with a segmented ring to trim it out.

The ring is made of walnut and accented with bands of Paduk wood.  The speaker is caged in a custom copper cage where I added a blue patination using various salts and acids.  The cabinet is made of walnut, and the controls are mounted on a copper plate with a similar patina.  To visually tie the speaker cabinet to the control box, I added an oval window to the side and positioned the power indicator light, adding a soft glow.  Then I added a similar round window to the side of the control box; all openings are outfitted with a copper grid.  Finally, one of my favorite parts was to show off the fact that it was originally a vintage tube guitar amp.  I mounted the amplifier tubes on the top of the control box and protected them with rings of copper that had the same patination as the rest of the copper.
