I had a thought tonight about a cool amp top plate and found a gaggle of them on the bay. Flipped upside down and mount it on a walnut box.

Cool, this is just the ticket for MetallicAmp, an all tube, no glass guitar amp. All the tubes will be 1940's vintage metal envelopes. So there will be no plastic, glass, or sand(silicon). Maybe I can figure out how to eliminate the wood too.
I found a similar tray that weighs a bit less and costs $15 with free shipping. I had $3.78 in Ebay bucks that were near expiration, so, done deal.

You could have 1/2" rebar bent into a rectangle the player can sit on. Stack 8 of those up for a 4" tall chassis
A member here, W5JAG has run his SSE board through the dishwasher a few times to clean up the remains of failed experiments.
After spewing electrolytic goo all over one of mine several years ago, I tried it.....it did look nearly new despite several years of failed experiments. Now after 10 years of being used as a test mule, it's still kicking.
Yes, I stuck a 4D32 in an SSE. It did not work well in SE. I haven't needed to remove the big socket yet. This board lives in my junk box and is reserved for experiments. It's used here to demonstrate some power supply voltage measurements.

How about heavy , maybe 3/4" diameter standoffs on the perimeter flat as feet/legs . . . . .and the underside of the raised dividers might make good wiring conduit.
I got some surplus 5/8 diameter hex standoffs for pennies on the dollar for just this purpose a few years ago. No doubt they were surplus because of the pretty darned fuggly purple-faded-to-sickly-pink anodizing they were sporting.
. . . . And if scratched up old surplus isn't what they're after, the discerning gourmet might find satisfaction here. . . . . With engraved top caps no less . . . . .
Something that would be just right for a single channel...they all seem to be appx. 15 inches by 8 1/2 inches...the textured no-slip coatings are thick, & the thickness is about 3-5 mm.

djn,
Good idea for an amplifier top plate.
I used to hang on to those stainless steel compartmentalized food plates.
That was a real good idea at lunchtime when the Destroyer was taking rolls (+/- 45 degrees, 90 degrees peak to peak).
Lunchtime is much more calm now, I can be at home listening to any of my sound playback systems using vacuum tube amplifiers of my design, driving un-modified, and modified speakers.

This is too cool, djn! Your previous endeavors are proof that you're one who thinks - quite literally - out of the box. Please keep us posted.
Those metal chow trays always make me think of that scene in M*A*S*H where Igor's culinary skills (or lack thereof) get the better of Frank Burns. 😀

Manufacturing used to clean PCBs in Freon Tanks.
Then Uncle Sam made Freon Forbidden.
Manufacturing stopped making the P6015 40 kV probe, because it was charged with Freon.
Manufacturing started making the P6015A 40kV probe, it had Gel filler. It could never meet the same dissipation specifications as the old Freon charged probe.
Uncle Sam called the Service Department, and wanted their P6015 probes recharged with Freon.
Sorry, your Legislative and Executive departments has forbidden the use of Freon.
Talk to them, or purchase a P6015A.

We had Freon based vapor phase degreasers. The Freon was boiled in the lower compartment the hot vapors would rise up through the middle compartment where the perforated trays that held the PC boards passed, continuing up toward the cooling coils in the top compartment where the Freon would condense back to a liquid, pass through a filtration system to capture the nasties removed from the boards, and be returned to the bottom compartment.
We tore down one of these machines every other week or so for a good cleaning with acetone and new Freon, then it was returned to the assembly line. It was discovered that these machines had several useful features for those of us who built things. They made junkyard quality car parts look and work like new, especially spark plugs, carburetors, turbo chargers and the like.
Freon went away in the 90's I think, long after I was out of the Mr. Fixit business at the plant. They got some wicked smelling terpene solvent based on oil from orange plants. For the first week or two everybody thought it was nice, smelling a lot like an orange grove.....then people got sick, and the smell became nauseating.....that lasted a few months, then the water soluble fluxes came, only to be replaced with no-clean flux.
BTW, there are some solders sold through Mouser, Digikey and others that use a water soluble flux. They might be fine for the average "maker" working with a 5 volt Arduino. DO NOT USE this stuff on a PC board based tube amp or anything with several hundred volts on it. The flux residue left behind from this solder can absorb moisture from the air in a humid environment, leading to a slightly conductive path. This can cause an arc that could carbonize the PC board leading to burnt parts. This happened to a customer's board that was left in his garage for a month or so, and I have been able to duplicate this scenario with a board left in the garage as well.
Seems this amp really needs a good cake pan to go with the tray. Cakepan tube amp has been done, just not with the tray on top.
