Thanks for reading the post and for your prompt response Lawrence.
The circuit is attached - what are your suggestions?
Basically, I'm intending to power the unit from a traditional transformer/rectifier/capacitor wall-wart rather than a modern switched mode supply, and trying to keep it as simply as possible, though have already added C8 with C1 in parallel, though another cap won't complicate life too much! I don't want to build it and find it doesn't perform well, but that said, with this - as with the original design and the Mini-Mod - the original design concept was to keep things as simply as possible and easily reproducible.
All good clean fun!
