Hi.

I also built the Raymond Haigh wobbulator featured in RB magazine and it is working well. I also seem to remember there's a mix up with the location of two of the four Toko coils. It's probably the board layout rather than the circuit diagram but will have to verify this.
When I eventually finalise the layout of my workshop then I hope to use this unit more frequently.
I used the front panel legend as per the original article, it's just a paper copy with a piece of perspex protecting it. A couple of pics of the completed unit attached.

Regards
Symon.

EDIT: Just reread David's post #26 re the transposed Toko coils
