Hornby Skewes Shatterbox 4d4f02c6f7fc

 Slightly modernized and improved. The original  ran on negative power supply with low gain jellybean PNP silicon transistors with BCE pinout. This layout calls for low gain NPN silicon transistors with CBE pinots so you can easily socket the normal suspects like PN2222, 2N3903 etc. And a trimpot for the biasing the fuzz section replaces … Read more
