211 Drives 211, Part 2

Hi!

Assembly of the 211/211 amplifier has begun. The metal plates for the internal construction are done. These will carry all the parts and will be stacked in a sandwich fashion. As mentioned in the first part, this time a completely new chassis design will be used. Even a new shape. It will be round:




The photo above shows the top plate with the tubes plugged in.

These are all the metal plates for the sub assemblies for the amp:




Cutouts for sockets, capacitors, connectors, etc. And screw holes for transformers and chokes.

After the parts are attached it looks like this:




These are the assemblies with output and interstage transformer (left) and the last stages of the B+ filtering. Oil caps for the filtering and ultra path connections.

Capacitors are mounted to the plates with aluminium rails on the under side:




Filament and B+ chokes are on the bottom plate (left):




The bottom plate also carries all connectors. Input transformer and bias resistors are mounted on the underside of the top plate (right).

The Connectors will be accessible from the bottom:





Stay tuned for updates as the construction progresses.


Best regards

Thomas
