Aaaaargh. Right that was a silly mistake, thanks for spotting it.
I've reversed the cap, and checked over the remaining components again. Unfortunately no improvement to the sound, so I suspect there's another problem with my build - dodgy soldering/solder bridge I've missed/faulty component.
It's not a very large board, so I'll populate up another one and see how I get on, and if there is any difference there.

One thought that occurred - I recall from the WH Red Llama thread that it is important to use the unbuffered version of the 4049 for the Red Llama. I have used the same IC here, with the 'UBE' suffix. Might it be the buffered version that is necessary?

Again, thanks for your help.
