Marconi TF 2103 Wide Range Oscillator • 1970s made in the UK

Rare vintage wide range oscillator built by Macroni in the UK 1970s. This unit is in great physics condition and is still working with a couple of issues.

The third or middle frequency range selector switch (1 to 10 kHz) is a bit fiddly. Sometimes is does not engage and the button needs a little push to go into the correct position. When it is engaged the oscillator is working, but the square wave does have a couple of dead spots in this position only. The sine wave does not have this issue and works well in all settings, the square wave doesn't seem to have issues in any other settings either. Other than that the unit is working well.
