Re: HH Scott 340 Receiver Rebuild
The volume pot was dripping DeoxIT. It's a great product but I think some folks get carried away with it. The pot felt very rough and when I disconnected wires and Ohm'd it with an analog meter, needle movement was not smooth as pot was turned.
Tough spot but you can remove a couple screws each side and tip front panel forward. Too many wires to disconnect and remove that front plate.
I watched a video where a guy successfully resorted a soaked pot. It was suggested to soak the wafer in rubbing alcohol to dry it out. Clean the element surface with straight DeoxIT D100L, dry. I tapped on the rivets to tighten connections without breaking the wafer. The center contact ring was loose on both wafers.
Fader grease is applied sparingly on metal-to-metal surfaces and on raised ring where it contacts back of plastic wiper. Feels like a new pot and both measure well.
It's busy with stuff connected to it. You want to get it back together right. A couple of resistors connect from below.

Re: Post a picture... any picture
The Lockheed Martin X-59 is probably the strangest airplane ever designed. Its razor-sharp nose takes half of the airplane’s length; there’s no cockpit in sight; the wings are tiny compared to the entire fuselage; and its oversized tail engine looks like a weird hump about to fall off. Of course, there’s a method to this madness. The design is the secret sauce that has produced a true unicorn: a supersonic jet that doesn’t boom the hell out of people and buildings on the ground.
The sonic boom is a phenomenon that has long been the Achilles’ heel of supersonic flight. When an aircraft travels faster than the speed of sound, the compressed air molecules against the body of the plane produce shockwaves that merge to form a sonic boom, a loud and disruptive noise heard on the ground. This noise has historically been a significant impediment to the commercial viability of supersonic flight over land.
The X-59’s “quiet” supersonic boom isn’t made possible by expensive magical materials or exotic engines, Richardson explains. “There is no radical technology in the airplane itself. It really is just the shape of the aircraft.” And if the shape looks more like an anime alien spaceship than an actual vehicle created by human beings, that’s because it was dreamed up in another dimension—by computers and humans—through special software created by the Bethesda, Maryland, company’s engineers.
As planes started to go supersonic over the continental U.S., the sound explosions became so much of a problem that Congress banned supersonic flight over land in 1971, a move that was later followed around the world.
