AV 32B SL datasheet
This tube is an AV300B SL with extra cooling plates. It will operate like a normal 300B, in any amplifier. The only difference is, this tube allows maximum 65Watt plate dissipation.
Features
- This tube uses AVVT's unique Super-Linear Patent (Note1)
- AVVT's patented ribbon filaments with 16 flat Surfaces, for more linearity
- Two extra large getters
- Unbreakable Hard-Glass. Bulb is larger sized than normal 300B.
- Anti-microphonic Suspension in Tube Top
- All 1999 (and later) AVVT tubes use unbreakable hard-metal filaments. (Note2)
- Ceramic UX4 Socket with Gold Plated pins

Note 1) Super Linear platesare based on an exclusive AVVT patent. The cold ends of the filaments do not have a very good function, and cause distortion. This tube has four cavities inside the plate, that cover the cold ends of the filaments. These cavities are covered by four nickel plates, that you can see from the outside. Within these cavities, plate current will not be able to flow, and this disables the emission of the cold end of the filaments.
Note 2) Hard-metal filaments are operated at much higher temperature than normal tubes. This tube will glow bright orange, instead of the dark orange color of nickel filament tubes.
Note 3 Individual Test data, such as: Matching Data, Grid Current, Vacuum, Filament Current, etc, are on the Certificate that comes with each individual Tube. Each tube has is numbered, inside the bulb with a metal Tag
Note 4 Typical Data are choosen higher as for the 300B. When operated at lower power level, refer to typical data of the 300B for mu, transconductance, and Plate Resistance. You can test this tube with normal 300B settings. |
