211 -The Next Generation- Part 15 : 6HS5/211 finished

Hi!

Finally here are photos of the finished 211 mono amplifiers with 6HS5 driver.




The development of the layout and the assembly have been shown in previous posts. This is how the finished amp looks like:








The dimensions are: 320mm wide by 620mm deep. The wooden body is 125mm high. Overall height about 310mm. Quite some boat anchors!






Both amps side by side:




First I was a bit sceptical if the design with the many transformer covers on top would work. But as it was finished, I liked it a lot.




View from the top:





The sockets of the driver and rectifier tubes are mounted a bit recessed below the main plate to provide a good clearance distance for the high voltages.






The amplifiers in operation:




Glowing in the dark:






Close up to 211 and 6HS5:





The rectifiers:

  1. They look awesome. Must have sounded beautiful too. How much will something like this cost?

  2. Look great. Love the veneer on the sides -- classic.

  3. I've considered using Lundahl transformers before, but didn't want to deal with enclosures for them.. How do these ones you're using deal with the heat that the transformers create, so that it doesn't get trapped inside the enclosures?

    1. Hi!
      The output transformer and B+ chokes don't get warm at all. The filament chokes get a little bit warm, but not much. The power transformers get the warmest. But they are designed such that they can be operated within such enclosures. There are venting holes in the main metal plate underneath the transformers. If you use transformers which get very hot, you probably can't use such covers.
      These covers are also available through me.

      Best regards

    1. Hi!
      The covers are metal (Aluminium).
      I also sell these covers separately. They are available in different varnishes. Here a description of the covers:
