Hi David,
Once again, I'm in awe of the lengths you will go to to finish off a project! I don't realistically expect I shall ever get round to putting mine in any form of case, let alone a handmade comb jointed box complete with printed front panel!
I don't suppose you would consider making a small batch of bare PCB's for Forum members? It would certainly make construction easier!

Howard, Good to hear you have successfully completed yours- well done!

I am planning to add an auto level control circuit to mine to keep the modulation depth at optimum. As suggested by other forum members, this will be based on the BA3308 chip. I now have one of these to play with so hopefully I can come up with a design whereby the Minimod can be fed from a wide range of input levels.

Cheers
Nick
