Two n-p-n silicon planar epitaxial transistor sections in one
package to be used as push-pull amplifier, primarily
intended for use in linear u.h.f. television transmitters and
transposers.
The package is an 8-lead flange type with a ceramic cap.
All leads are isolated from the flange.
1. Three-tone test method (vision carrier −8 dB, sound carrier −7 dB, sideband signal−16 dB), zero dB corresponds to
peak sync level.
2. Power gain compression is 1 dB.

The circuit and the components are on one side of the PTFE fibre-glass board, the other side is unetched copper to serve
as a ground-plane. Earth connections are made by means of bolts. Additionally copper straps are used under the emitters
and at the input and output to provide direct contact between the copper on the component side and the ground-plane.
