211 -The Next Generation- Part 14 : 6HS5/211 assembly

Hi!

In Part 13 of the series of posts about my next generation line of 211 amps I showed how the layout of the refreshed 211 mono blocks with 6HS5 driver is going to look like. This post will illustrate the assembly process.




Contrary to the 801A/211 amplifiers this one has the amplifier section and power supply on one chassis. This means a lot of iron needs to be fitted in.

Everything is mounted on a single metal plate:




Here the sockets, connectors and switches are already fitted. The underside:




The interstage transformer is the only piece of iron which is placed inside. Many rails and bolts are needed to hold the capacitors which will all be inside:




For the further assembly steps the plate is fixed in a rig which makes it easier to handle:




Here all the chokes and transformers are already mounted on the top side:




The inside with some initial wiring before the capacitors go in:




Everything in place and wired up, ready for testing:




The amp can be tested in the assembly rig, before the transformer covers and enclosure are added. 5 covers are needed to hide these heaps of iron:




Stay tuned for photos of the finished amps!

Best regards

Thomas
