The price is for ONE tube 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.

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. They are carefully tested on my TV-7/U and my hifi system before being packed with NOS ranges from 110-120/56 min. If you are not sastisfied, please send them back with full refund within a month (of course you pay the returning fees). I guarantee the best quality of my tubes.

If you are not sastisfied, please send them back with full refund within a month (of course you pay the returning fees). I guarantee the best quality of my tubes. Thanks a million P/S: It is important to bear in mind that the shipping service I offer in the listing is $28.65 to all regions to which Vietnam post is available. Due to the bad epidemic, Vietnam post is not always available to some locations especially in Africa, some South American countries or even some Northern European nations. Also, it takes longer than usual (22-60 days depending on the distance and your local customs). So, please wait patiently email/message me if there is any problem occurred before opening disputes on ebay. It will make the situation more complicated and obviously affect my selling performance.  For that reason, please ask me before bidding. Besides, if you need the tubes urgently, you have to pay an extra of $45.75 (taking 10-12 days) or $68.75 (taking 3-5 days) by DHL to all regions world-wide. Thanks a million
