Re: Marconi 702. Sound problems.
The CRT is out so now I can gain access to the power supply unit in order I can take pictures of it for another forum member. The RF unit must also be removed because the sensitivity control needs replacing.
For safety's sake buy a visor so that your eyes and face can be protected from implosion. It's worth bearing in mind that these tubes are almost eighty years old.
