MC1496 Modulator and Mixer

In this video I do some playing around with the old school MC1496 Mixer and Modulator IC.

UPDATE: I have just realised that I drew the schematic wrong at the output. I should have had the transistor base connected below the load - not above. I'll correct the schematic on github

The kicad schematic is up on my github repo

Heres a PDF version of the schematic
