SuperNick (Nick) has finished assembling the x0xb0x.

There is, however, one tiny problem.

No sound.

Earlier in the build we had successfully confirmed sawtooth and square-wave output from parts of the synthesiser, so this does not mean nothing ever worked.

It means the completed system has introduced a new fault-finding adventure.

Naturally.

See if you can spot the point where the raving cats appear.

Because apparently diagnosing an analogue synthesiser was not enough entertainment for one video.
