From the post

Here’s tasty, oldshool Interfax – Harmonic Percolator vero project

Cross between fuzz and overdrive.

Hybrid germanium/silicon transistors with germanium diodes

You should be good with 0.1″ pitch stripboard as well as with wider 0.15″ doing this build, depend on what enclosure you’ll chose to use

0.15″ pitch vero is recommended due axial components use
