Emission Labs, 520B-V3, 520B-V4 Rør - Parret par/2stk.

The 520B is a long Anode Version of the older 52B, with many technical improvements added. The EML520B is a state of the art product, in the family of the 300B tubes. This powerful tube is recommended for new designs. The 520B has the same outside dimensions as the '845' tube, but longer Anodes. All critical parts, like filaments, grids and Anodes are constructed of hard metal for higher reliability and reproducible quality. Note the relation between the tube base, and and the glass bulb. Then compare this with our 300B. This gives you some idea of this tube's size.
