This is one of the first-generation tweed-covered Deluxes, dubbed the "TV Front" because of its resemblance to a 1950s television. The octal preamp tubes provide an excellent, midrange-focused sound, setting it apart from the later 9-pin circuits. The power transformer has been swapped for a Hammond, which matches the original voltages perfectly. With the original Triad output transformer still intact, the sound of the power section is well preserved. There is also a small hole drilled in the lower back panel, likely used as a jack at some point.
Internally, the power cord and electrolytic caps have been replaced. The coupling caps have also been swapped, as the original wax types tend to fail over time. See circuit pictures for further details. These amps offer a charming, great-sounding alternative to the more expensive narrow-panel models from the late ’50s.
