Probably should explain: These feet are made with a series of miter cuts, then the 2 halfs are glued together and they are made from red maple, most of my wood projects, 98% or more , are done with traditional handtools—these feet aren’t too difficult one just has to pay attention
Nice work! Unfortunately woodworking is not my friend!

Your comments are appreciated very much
This was actually my first build from a schematic, had rebuilt/updated several amps/preamps/receivers and done a few kits, but nothing from scratch
From the inception my intention was to build something special, but we know how that can go awry
Given that Paul designed it and helped me through all my rough spot, really didn’t want to embarrass him, so I’m really pleased with the results, the functionality is exceptional, abs the best amps I’ve ever had….

With the help from the exceptionally talented @Andre Garcia we’re working on some plates to attach to the amps, probably the back plate of the Lundahl OPT but TBD
Here’s a trial run set, actual plates to come….

They're wood. That too was a subject of much discussion and soul-searching. ;-) Personally I like the result.

Thanks again….
Lots of trial and opinions, tried multiple different commercial options, only showed 3 or 4 of them, then lots of wood designs that just didn’t work.
Originally thought round or stepped/graduated feet would compliment the case design but they looked so out of place (trying different sizes/colors) l didn’t even post pictures of them
In the end, it was all a very rewarding process/project

Thank you for your comments
Didn’t go in to detail here about my 300B tube comparisons, but in short the JJs lacked the bass of the Gold Lions and the Psvanes…the GL & Psvanes were extremely close in my experience, might even give the edge to the Psvanes, but given the price difference, the Psvanes became the clear winner for me…
However, with all that said, I’d be content with any of the 3 compared

The back of the OPT's would be a good choise. If they were mounted on the front of the amps, front of the OPT's, or even on the top of the OPT's, it would take away from the esthetics of the amps. I personally think it would take way from the looks of these beautiful amps. Your eye would be drawn to the plates, not the amps themselves?

I’ve come to the same conclusio, the back is the most appropriate location and there isn’t room on the rear wood, so the OPT rear plate is the next best optionThe back of the OPT's would be a good choise.

Not long ago I’d posted a thread asking about SET amp kits and got lots of fabulous feedback….wanted a project that would be satisfying, challenging, and give value added end results. @Wardsweb offered to lend me his amps and provided a detailed build schematic so that got me thinking about...

Just wondering why the Western Electric trademark name yet your not using there tubes.

Because of what it is—Paying homage to the amp’s original roots/design, obviously anyone can tell it’s not an original Western Electric 300B SE amp, wouldn’t matter what tube(s) it has…..Plus all these 300B tube producers wouldn’t have a product if not for the Western Electric 300B tub/amp.
Other than that it would be an argument surrounding opinions on which tube sounds best, opinion because my understanding from technical tests and comparisons is that many brands of 300Bs test the same, can’t be distinguished from the other brands in electronic tube testing.
There’s some discussion of the choice in the build thread, albeit not along the lines of your question….

Almost finished with the preamp accompaniment to the above, it’s working but, in need of a few finishing touches Wood is Caribbean Rosewood and Birdseye Maple
The Line Stage is 6H30 based and the Phono Stage is based on the Juicy Tercel II
Volume control is the Khozmo Autoformer Volume Control AVC – with remote….

Oh! I forgot to ask, how did the Khozmo AVC work out? Sound good?
