300b Valve Amplifier

grabcad

This is a 300B single-ended valve amplifier that remains unfinished; it's just waiting for you to complete it! The Sowter transformers add quality to your build, while other components were sourced from eBay or made specifically for this project. Two .zip files are available for download: 300B amp Assy Heavy.zip contains the entire assembly, while 300B amp Assy Lite.zip has a smaller file size since it omits valves and rotary switches that you'll need to supply yourself. Recently, the user completed a KT88 amplifier and shared his listening experience. The 300B amp will eventually be finished in a larger case, but no rush - the KT88 amp is straightforward and efficient.
