The price is for ONE pair Telefunken G73-R black coated glass, NOS, laboratory product, very reliable version, Tested Nos tightly matched, excluding shipping. I have some carton boxes each contain 100 pieces so they are all unused with NOS testing values and tightly balanced. 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. The finest West German manufactured Telefunken tubes with diamond marked, these have G73R hand written or Lab stamps on the outside black shield coating. Records indicate they were only available as spare parts for Agilent or H-P equipment. Critical use in hospital and aerospace equipment demanded tubes with extremely low noise and tightly controlled output. The ultimate tube for Hi-Fi, tube mics and mic preamps, these tubes are very fine, highly rare and in great demand. Authentic, the real deal, the bottom of the glass is diamond marked. Matched pairs and quads are available with tightly controlled transconductance from section to section and from tube to tube. Astonishingly accurate, the sound image blooms out of a dead quiet background.  If you want the best 12AU7 variant available anywhere, put these in your cart. You can order the number you want since there are hundreds of them in stock.

If you need the tubes urgently, please pay an extra to use express services like DHL, FedEx... which costs about 63 pounds taking 3-7 working days depending on your local customs. Please let me know soon. Happy bidding. Thanks P/S: All the tubes are under one-month guarantee and return is accepted but buyers have to pay the returning fees.
