Product Summary

With strong performance and pristine condition, this special pair of vintage tubes are priced to sell! Many tube enthusiasts began their journey with Bugle Boy tubes, right here at Soundlumia, and we believe that's the best choice they have ever made just like the audiophile friends among us.

Sound Qualities

You get the "textbook" Siemens 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 Siemens tubes. Bass is deep and well controlled and the accuracy feels very similar to the high end German ECC82'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: 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

This set was tested and certified by RoeTest V11 tester with the following result: 

Measured transconductance (GM): 2.66/2.52 mA/V  - 99%/93%  (100% = 2.7 mA/V)
Measured plate current (IA): 6.595/6.19 mA  - 110%/103%  (100% = 6.0 mA)

NO shorts, leakage or gas. NO noise or microphonics.

Curve trace is also included in the original RoeTest report.

Appearance & cosmetic condition

We treasure this tube because the pristine cosmetic condition is in - over 90% of the paint is intact. The Heerlen date code etched on the glass is perfectly visible on this single tube.
