The Classic Tone USA 40-18038 and 40-18039 transformers are premium components designed for guitar amplifiers, specifically for those seeking the authentic tone of a JTM45 circuit. These transformers are meticulously crafted to deliver the rich, tube-driven sound that is reminiscent of iconic British amplifiers.
The 40-18038 is a secondary-side tapped transformer, which provides flexibility for players who want to fine-tune their tone. This transformer comes with 4, 8, and 16 taps on the secondary side. This versatility allows guitarists to choose the optimal output voltage for their specific amp design or personal preference. With a primary voltage of 120V, this transformer delivers a maximum secondary voltage of 432V.
The 40-18039 is an output transformer, designed to match the 40-18038 in a JTM45-style circuit. It also offers 4, 8, and 16 taps on the secondary side for adjustable output voltage. This transformer has a primary voltage of 120V and can provide a maximum secondary voltage of 432V.
Both transformers are built using high-quality materials and construction techniques. The core is made of MOTOX, a proprietary laminated core material that ensures superior magnetic field stability and reduced eddy current loss. The windings are made from heavy-gauge, enamel-coated copper wire. This results in a transformer that delivers a balanced, clear, and authentic tone, with minimal hum and noise.
Classic Tone USA's 40-18038 and 40-18039 transformers are the perfect choice for those seeking to build or restore a JTM45-style amplifier, or for those looking to add some classic British tone to their rig. With their flexible tap options, these transformers offer a wide range of tonal possibilities, making them a must-have for discerning guitarists and tone enthusiasts.
