Variable--pentode - Triode Pentode; gm 2 mA/V; Triode 20; Ih 0.2 A.

This is a DARIO ECF-1 / ECF1 tube, NOT a BELVU. The picture shown is to give the customer an idea of what the ECF-1 / ECF1 looks like and is for a visual display purpose only.

Patented in 1940, the Dario ECF1 was developed to enable the design, together with an ECH3, an EBL1 and a rectifier valve, an adequate superhet with six tuned circuits. The ECH3 is used as the frequency changer, the triode of the ECF1 as 1st AF stage, its pentode as IF amplifier, while the diodes of the EBL1 are used for detection and AVC and the pentode section works as the AF output stage.

The internal electrode assembly of the ECF1, which was taken from the ECH3, is interesting. Mica plates, holding and screening plates and the triode system are identical, only the grids of the pentode section are different. It is amazing that this pentode contains four instead of three grids, of which the second and the third grid, connected in parallel inside the valve, serve as screen grids. Couldn't one simply have omitted a grid when using the ECH3's structure for the ECF1? The dimensioning of the grids may be different. This is clearly visible with the outer grid in each case: as the second screen grid in the ECH3 it has a fine pitch, while it has a coarse pitch as the suppressor grid in the ECF1.

Why ECH4 and ECF1?

One may ask oneself, why at the same time and for the same design of circuit were the ECF1 and the ECH4 released? The answer for this is somewhat complicated: The heater current of the ECH4 amounts to 0.35 A. Thus it is suitable only for parallel heaters and so precludes its use for AC/DC sets. For the latter, a suitable 100 mA U- series was released, consisting of UBL1, UCH4 and UY1, but this series was not available in all countries. A valve complement of 2 x UCH4 + UBL1 + UY1 needed a heater voltage of 145 V and therefore offered no advantage for countries with predominantly 110 to 130-V mains (e.g. France, Spain.) The ECF1 however could be used there both with parallel heaters, as well as for series heaters with the C- series of valves. A valve line-up for 110-V AC7DC sets was then ECH3, ECF1, CBL6 and CY2. This, like the alternating current version with an EBL1 and 1883, was very common until superseded by the Rimlock series. In countries, where the ECF1 was established, the ECH4 remained mostly unknown, conversely, the ECF1 was not to be found in ECH4- countries.
