| The JAN-Philips 5751 is our first choice for taming high gain guitar amps while vastly improving the clarity, smoothness, and vintage tone! They still have plenty of gain but if you have a high-gain preamp that does not have that classic crunch characteristic, the 5751 tube will do wonders. In hifi preamps and CD players, the JAN-Philips 5751 will lower noise floor and sound smoother and clearer in place of many 12AX7 tubes. Availability: Usually ships within 24 hours.
