1 Powdog 6 months ago While fitting a new cabinet for a 5F1 chassis this past weekend I started thinking about a new amp build. A Supro Spectator squeezed into a Tweed Champ chassis. Instead of making another hole for the Tone control I used a stacked concentric pot and moved the power switch to the Fuse hole. I also added a third Mic input jack in the triangular configuration Paul Barth used on his amps. The pilot light is a really cool dimmable unit I’ve had for years.
