I'm glad that you asked for photos! Pictured: White GE labeled 5814, with short post, slightly lighter black plates, bent square getter, copper rods, silver clips and a double top mica. These also have a 5814 etched code at the top of the glass face. Pair White CBS Hytron labeled 5814 with medium post, black plate, bent square getter, copper rods, silver clips and a double top mica. Red labeled, CBS labeled 5814a with high post black plate, bent square getter, copper rods, silver clips and a double top mica. I will re-evaluate these using an Amperex 12AU7 long plate top mica mounted getter as a control behind a pair of Gray Plate Sylvania 5751s and tell you what I find. Here are my impressions:
The Amperex is darker in character with deeper more powerful bass than the above tubes. It would probably work well with the Raytheon 5751 windmill getter as a counterpoint. The GE labeled are more lucid, immediate, have seemingly better focus and more realistic mid range timbre. Nicely detailed very listenable. I find myself disinclined to pull it. This is clearly a Hytron tube or a mighty good copy! The red label CBS have a similar tonal balance but the bass is not as impactive deep or defined, the mid range is less present, a little thinner and has a slight electronic quality compared to the GE labeled above. This is all just relative, it's still a pretty good sounding tube. The white label CBS Hytron sounds like the GE, present, lucid, dynamic. It might be slightly more vibrant than the GE, but at this level, it might be my imagination.
The real beauty of music lies in the ambience of the venue.
