Frequently Asked Questions
It’s an inspired recreation, capturing the core sonic character but lacking the sheer scale and complexity of the original. Expect similar warmth and compression, but with a slightly more modern feel.
Heritage Audio designs and specifies these transformers; they aren’t generic parts. This contributes significantly to the module’s unique tonal signature.
While it’s not excessive, ensure your power supply has ample headroom to avoid noise or instability; a dedicated, high-quality power supply is recommended.
