Hi all,
since it's a bit difficult to get the original parts for the dynalo, I've redrawn a pcb, using 2SJ74/2SK170 at input and bc550c/bc560c for the rest.
The pcb is inspired by the one provided by Kevin Gilmore in the original article, with the addition of some local decoupling caps. It's single sided (red tracks are jumpers) and avoid small tracks (most are 56mil), to ease home-etching. Dimensions are 6*10 cm.
So, what do you think ? What could be improved ?
