The PSVANE ACME 274B
 
The finest rectivfier tube ever made!
PSVANE mentioned these desgin factss as a remarkable details:
  • 5+ years of R&D poured in to create this Supreme series and world's first 3D designed tube structure
  • Patented hybrid plate design - combination of graphite and mesh material first time used at the same time on high power output tubes (845, 211, 805) to achieve synchronized expansion even at 600 Celsius temperature, high emission capacity, and super stability.
  • Overhang filament structure on 300B, 274B, 2A3 model to achieve very airy and high resolution sound reproduction. Vintage style globe shape glass enclosure on these models.
  • 5cm diameter larger glass enclosure on 845/211/805 than regular series to allow quick heat dissipation and enhanced stability
  • Teflon base with sand blasted aluminum cover - no finger print residual!
  • German solder used in pin connection and of course, gold plated!
