Twin Triode Tube High-Mu
The TAD 5751 HIGHGRADE is a high-gain, dual-triode tube offering a smooth, clear sound. When used in a HiFi preamplifier, the TAD 5751 will provide a lower noise floor and a smoother, clearer sound signature than most 12AX7 tubes. It will be able to replace tubes such as 12AW7A/WA, ECC83, 7025, etc.
