Sound Sample:

Perfectly matched & balanced pair of vintage Mullard 6DJ8(ECC88) tubes - Heerlen, Holland sound from 1974 - Strong NOS - Very Rare

Product Summary

With strong NOS performance and practically same date codes, this special pair of vintage tubes are priced to sell! Many tube sound enthusiasts bought Holland 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

You get the wonderful 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, thanks to the very rare dimple disc getter on these tubes. Vocals are intimate, sweet and forward (but not right in your face.) Bass is deep and well controlled and the accuracy feels very similar to the high end German ECC88's (Siemens, Telefunken.) 

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: Liquid Platinum Tube Amplifier by Alex Cavalli 
 - 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 NOS (100%+ nominal mutual conductance) on a reliable Mercury 2000 tube tester with the following result (mutual conductance both in uMhos and in percentage of nominal):

Tube 1: 13,500/14,000(108%/112%) 
Tube 2: 13,000/13,500(104%/107%)

Good tubes start around 7000 and new tubes (incl. NOS/NIB) 12,500 - 13,000, and Mercury 2000's rated mutual conductance (nominal) for new tubes is 12,500. Test result can also be seen in the pictures. In case you wonder what all these numbers would mean to your sound experience, it's actually quite straightforward: mutual conductance directly translates to tube's ability to amplify sound so the higher the numbers the stronger. 

Appearance & cosmetic condition

One tube is in very good cosmetic condition, and the other tube's paint has mostly worn off but the Mullard logo still can be seen. The close Heerlen date codes are perfectly visible on both tubes:

delta 4J2 (delta = Heerlen, Holland, 4 = 1974, J = October, 2 = 2nd week of the month) 
delta 4J3 (delta = Heerlen, Holland, 4 = 1974, J = October, 3 = 3nd week of the month)
