Hello,

I have up for sale a Telefunken G73-R Red Label Version. Only selling it due to needing funds.

G73-R history - Surpassing the quality control requirements of the famous Telefunken ECC802S, these are extremely rare, limited production, black shield coated, avionics/aircraft grade, factory selected Telefunken G73R. Manufactured solely for Agilent Technology and Hewlett-Packard, the proprietary G73R part number and RFI/EMI black coat shielding indicate the highest quality grading on the planet. This illustrates exhaustive aftermarket testing for low noise, uniform output, low microphonics, freedom from physical defects, long heater life and an even, uniform cathode emission

Tube is in good working condition. It is a true End game 12AU7 / ECC82 tube.

I am looking for $330 shipped via PayPal G&S or $315 shipped F&F.
