Making of SE 211 Mono Amplifiers


A new pair of single ended 211 mono blocks is in the making. Here some impressions from the construction.

The amplifier consist of 4 chassis, each mono block has its own power supply. Each power supply uses 4 6AU4 TV paper tubes in a full bridge rectifier configuration.

The amplifier uses a 801A as driver tube. Same circuit as previous 801A/211 amplifiers.

Here some photos of some of the several modules:

The amps are tested before they receive their housing:

Photos of the finished amps will follow in an upcoming post ... stay tuned!

Best regards
