A PRECISION MATCHED VINTAGE QUAD of very nice, strong & early 1960s era Telefunken  12Ax7 (see beautiful photos of glass - exhibit E)  Munich factory / ECC83 tubes. These are all from the very early 1960's . They are beautiful examples of the very first of Telefunkens offered with the more rugged 14mm tall ribbed plate. 

The Siemens Halske factory made 14mm plates we the precursor of the later Telefunken(s)...these original cross seam Tele's have some very positive sound attributes that the later German tubes didn't always have...read on...

This type of early branded Telefunken Siemens is fairly rare. They are Siemens factory made for Telefunken back in the very early1960s  (Siemens without the 4x premium you'd otherwise pay!) ... You won't find the ubiquitous "diamond" bottom on these... rather note Exhibit D, where you will see etched glass codes... I61, I62 etc. These tubes are genuine West German production, Telefunken tubes. They were produced in the early 1960s by Siemens, likely at the Munich factory. So, to clear up any misconception, they are not Amperex, Mullard or Philips. This early variety of Teleunken is identified by the cross seam top, etched letters on lower side and the lower angular plate tabs, and quite a thick mica.

The sound of these is very special. Guitar players often favor them over the tall/smooth plate Telefunken of the late 50s -- the breakup is crisp.

The sound is definately Telefunken pedigree, with all of that creamy, lush sweetness -- but .. with brighter more defined highs compared to the smooth plate. If your past audiophile experience was with the tall 17mm smooth plate variety , give these 14mm Siemens beauties a try instead ... you may well like the delicate top end. For those who love the incredible long life that early german tubes give -- but found the smooth plate too rich or dark ... give these a try. These have the old world quality and will give any 12ax7a/Ecc83/7025 equipment a wonderful prescence. 

 All 4 pieces test well MATCHED / BALANCED for GM & Plate Current readings on Calibrated Lab Tester at the full, fixed bias 250V. Study the photos below ... it's the best matching set of these you'll see anywhere.  

A 4pcs are STRONG, test range 110% or better of new on ALL sides, they are low hours examples. 

 As found amongst a cache of stored spares, from a HiFi estate, in are old Telefunken boxes. The boxes are old and show many stains due to age (exhibit A, H). The early Telefunken tubes inside look beautiful and sound wondeful. 

Emissions test shown below for easy reference -- all sides are over 110% dynamic emissions. (see full lab test reports for GM & plate matching data below, exhibit A,D,E,H). The QUAD Tested strong and quiet on multiple testers. And, played in preamp....quiet to ear -  No microphonics. 

  They're guaranteed NO DOA,  very much happiness with these nice old tubes is assured!! 

 These are the classics;  West German of the 1950s & 60s have long set the standard for 12Ax7 dual triodes ... a very clear, detailed sound come from these ... and absolutely one of the silkiest, sweetest 12ax7's you can own.  Plus, genuine early Tele's go forever as well, outlasting most... (they have superior build quality) other brands of the era. 

Study the large photos & reports below, and you can see they are genuine Tele tubes and in great, matched shape!  

Strong tubes, and they sounded great, when tested in a hifi audio amp -- QUIET and WONDERFUL..

 Gourgeous Tele's. The flashing is beautiful & shinny, pins are straight. White Ink, clearly marked West Germany (exhibit A,E), a couple of tubes  may have partial ink, all have legible letters... see descriptions below...  

The units are matched construction, 14mm, top halo, and have etched Tele / Siemens codes in glass (exhibit D) .

Likely the most throughly tested set now online ... anywhere ... and so throughly checked out & fussed over QUARTET, all made during 1961 & 1962. 

A QUAD matched set like this is irresitable to both the collectors and audiophiles .... all over the world.  These will surely sell quickly -- Buy now to avoid a bidder's war.

Always carefully double boxed, and fast shipping with tracking #. 

Please see our excellent feedback, all happy 100% customers on vintage audio & tubes!
