Making of SE 211 Mono Amplifiers

 Hi!

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 top plates, gold anodised:





The amps are tested before they receive their housing:



The first of the mono blocks in operation:



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

Best regards

Thomas
