The New 300B Amplifiers


After the development of the 46 drive 46 amplifiers, I started to offer the 300B in a similar chassis style as well. Here is the first such built, a pair of single ended 300B mono blocks with 801A driver tube.

In terms of circuit and sound quality these are the same as previous 4 chassis versions with separate power supplies.

The tower chassis and layering the components inside in 3D fashion allowed a single chassis per channel.

This results in a more compact set up which requires less floor space.

Both monos side by side.

The tubes lit up:

The meter in the center shows the bias current of the output tube.

Another set of these in a different color scheme is in the works. Stay tuned.

Best regards
