Tuesday Tube : 10 Raytheon 4-Pillar

Another version of 10 tube with Oxide-Coated filament.

One of the best design and supported structure.

Raytheon 4-Pillar series have special design 
that tube lovers want to keep in their collections.

Red sticker of 4-Pillar was unique and always attractive.

Less transparent when compare with mesh plate 210 
but more impact and larger scale of music instruments.

Collective item with awesome sound too ;)
