6BM8 / ECL82 / 6F3P Svetlana NOS
The UCL82 is derived from the PCL82, which was designed for TV purposes. However, the UCL82 was almost exclusively used as AF pre- and output amp, although the triode section is greatly oversized for this application.
Just as the PCL82, the output section of the UCL82 has been designed for an anode and screen voltage of 170V as usual for universal ac/dc receivers.
Unlike as the PCL82, the UCL82 was not superseded by an UCL86 after some years.
