This project is an adaptation of an early 1970's electro~harmonics LPB-1.
The Linear Power Booster (LPB-1) is a handy clean boost when you have a single channel amplifier and you need that extra kick for your solo. It is also used for driving longer cable lengths or recovering signal loss after running through a long effects chain.
A BC239 silicon transistor is at the heart of this project. The circuit featured is a classic voltage divider bias.
This project is aimed at builders wanting to improve their soldering skills.
