6L6 SE-UL Top Plate Wiring Complete

In the last few days I’ve managed to get most of the wiring on the 6L6 SE-UL top plate complete. This includes all the preposterously large power supply filter capacitors.

So here is what it looks like with most of the components and wiring in place. If I could go back and update something in the design, I’d make the top plate about 2″ wider.

I say “most of the components” because there are a few things missing in this picture. The two 2H power stage filter chokes mount to the chassis. These will be wired in before securing the top plate (for better soldering iron access), then mounted to the chassis sidewall under the right channel output transformer. The main filter choke will likely go in last. It mounts to the sidewall under the power transformer. It gets wired into the terminal strip at the top of the two vertical (in this picture) filter caps.

After those major components get wired in, there are just a few basic connections to be made. Then it will be time to begin power up testing and doing voltage checks. Once I set the proper value for the dropping resistor it will be wired into the terminal strip at the top of the two vertical filter caps to set the final B+ voltage. I’m hoping to be able to get to the testing phase in the next week or so.

As always, questions and comments are welcome.

  1. I can’t remember…did you ever consider top mounted caps? Even one of those modern made multi section can caps?
    I tried to use a top mounted big filter cap once… I gave up when I couldn’t find a snap in cap with large enough diameter to work with one of my stash of clamps. Maybe some day stars will align…..
    I think your layout looks perfectly fine.

    • I did consider using a couple of JJ dual 100µf can caps (like these). I used these on the 6V6 Lacewood to great effect. But ultimately I decided to keep the components under the top plate to keep the layout as clean as possible.

      It looks better to me now that I’ve had a day to get used to it. Maybe today I’ll get started on the power supply inductors and getting the top plate installed on the ring frame.
