Four Point Five
This is our smallest amp at 4.5 Watts. The circuit is based on the 1955 5E2 Princeton (which is a 5E1 Champ with an added tone control). However ours is built in a tweed Deluxe sized cabinet with a 12" speaker and larger coupling capacitors (the original had smaller caps to reduce bass to protect the 8" speaker). This makes a fantastic recording amp for guitar or harmonica or a somewhat expensive practice amp! - there's nothing like the tone of an overdriven Class A amp and this is the only authentic way to get that sound without annoying your neighbors!
