Soundlumia's Opinion

Stronger than time! This is the classic beauty in sound, admired by audiophiles for more than 60 years and will still be our top choice in the next 60 years. The legendary Siemens tone is considered the "reference sound" for serious classical listeners who need to upgrade the sound quality at phono stage. 

The airy and transparent sound produced by these vintage Siemens tubes has been unrivaled even to this day. The magically extended yet never tizzy highs, coupled with the slightly focused upper mid-range, deliver a clear presentation of the entire frequency spectrum, completed by the precise and deep controlled bass. And the most defining sound characteristic of Siemens PCC88 tubes is their ability to retrieve the deepest levels of detail in sound, and these hidden sonic layers can go a long way to revealing the subtle ambient clues that help complete building a truly 3D holographic presentation. While as quiet and analytical as the best Telefunken tubes, Siemens PCC88's produce a warmer, smoother and more musical sound. 

Professional Tube Testing
Tube 1:

Measured transconductance(GM): 12.86/14.54 mA/V  - 103%/116% (100% = 12.50 mA/V)
Measured plate current(IA): 19.185/20.58 mA  - 128%/137% (100% = 15 mA)

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

Curve trace is also included in the original RoeTest report.

Appearance & Cosmetic condition

Despite some loss of paint on one of the tubes, this pair overall is in great cosmetic condition. The 2-line Munich date codes etched on the glass are visible on both tubes although you may need to look closer to see them completely: 

 

DJ0 ‡7C (DJ0 = PCC88 gen. #0, ‡ = Munich, 7 = 1957, C = March)
