Product Summary

Perfectly matched & balanced pair of vintage Amperex 12AU7/ECC82 Orange Globe audio tubes. With strong NOS performance and pristine condition, this special pair of vintage tubes are priced to sell! Many tube sound enthusiasts bought Orange Globe 6DJ8's as their first pair of vintage tubes to replace their JJ stock tubes...right here at Soundlumia's eBay store, and we believe it's the best choice they've ever made just like many others among us audiophiles.

Sound Qualities

We have evaluated at least 10 different versions of Orange Globe tubes and the mid-1960s' Holland sound is clearly among the best. You get the "textbook" Amperex Holland midrange presentation that is transparent, natural and expansive, with a slight touch of warmth that illuminates your musical world. The top end is super airy, smooth and nicely extended like one would expect from the best Siemens tubes. Vocals are intimate, sweet and forward (but not right in your face) and that always reminds me how the vocals sound on the best Mullard tubes. Bass is deep and well controlled and the accuracy feels very similar to the high end German ECC82's (Siemens, Telefunken.) To see how these sound differently from their German counterparts, please feel free to take at a look a wonderful pair of Telefunken ECC82 tubes in NOS condition from the 1960s we have in stock here: https://www.ebay.com/itm/266393604277

Professional Sound Evaluation

The pair worked wonderfully and sounded terrific in our professional studio setup for monitoring. 

 - Input: Cambridge Audio CXC V2 dedicated CD transport + Schiit Audio Bifrost 2 Multibit DAC
 - Amplification: Woo Audio WA7 Fireflies (3rd gen) Balanced Headphone Amplifier
 - Output: Focal Clear MG Pro open-back headphones

Our full tube sound review was written 100% based on the actual listening experience while this pair of tubes were running in the system described above.

Professional testing & sound evaluation

Both tubes tested Strong NOS (110%+ nominal mutual conductance) on a reliable recently calibrated Mercury 2000 tube tester with the following results (mutual conductance both in uMhos and in percentage of nominal):

Tube 1: 3,240/3,420 (108%/114%)
Tube 2: 3,050/3,150 (102%/105%)

Good tubes start at 2000 and new tubes (incl. NOS/NIB) 3,000 - 3,100, and the Mercury 2000's rated mutual conductance (nominal) for new tubes is 3,000. Test result can also be seen in the pictures. In case you wonder what all these numbers mean to your sound experience, it's actually quite straightforward: mutual conductance directly translates to tube's ability to amplify sound, so the higher these numbers the stronger. 

Appearance & cosmetic condition

we treasure this pair because the pristine cosmetic condition the two tubes are in - over 90% of the paint is intact. The Heerlen date codes etched on glass are perfectly visible on both tubes. What a rare find! The Orange Globe logo is also visible on one of the tubes as well.

Gf8 delta 0A1 (delta = Heerlen, Holland, 0 = 1960, A = January, 1 = 1st week of the month) 
Gf8 delta 0D3 (delta = Heerlen, Holland, 0 = 1960, D = April, 3 = 3rd week of the month) 

Packaging

This pair of tubes will be packaged in the new white generic tube boxes, secured by a handmade paper ribbon (by courtesy of Soundlumia.)
