At least I have a Wye transformer so I'm to code. I like to keep all my power ground referenced. Putting 10 pound of machinery in a 5 pound building has my machine quite close together I do want to someday put my hand on one and touch another and get zapped. I'm very interested in safety as it will be me that get hurt!
Yes I know pots are stack able, done it may times but some pots are not. The one in my machine is not stacked the switch is part of the main housing. I'm in the middle of no where. Since Radio Shack is gone we have no electronic supply house. Even when Radio Shack was here the slowly went out of the component business but at least it could be ordered.
One in my machine is about 1" in diameter possibly 1/4 watt maybe 1/2. I'm thinking a larger diameter pot will give me finer control at least it won't hurt to put it in, lots of room!
For no reason I can actually recall, I looked up their company background and discovered I had become a Digi-Key customer in their earliest years and still am. Allied Radio and Lafayette long before that. Also Mouser a tad more recently and Newark from the late 1960's onward. Power-One, first year, too. Arlington Electronics, Capitol Radio, and for a time Potomac Aviation and Marine were the only "local" places worth a damn, Metro DC.
Radio Shack was never worth spit, their best days, unless you expected to build to whatever hobby-schlock they HAD instead of what you NEEDED - MIL-SPEC or industrial-grade as often as not for my needs.
"Fun" was having to alter 2 dozen telco rackup line units from single-output channel to dual in a posh suite of the Okea Plaza hotel, Tokyo for gear installed practically next door, KDDI, internationals gateway switch center.
The goods had been designed for dual-channel, had been so promised on contract for least-cost routing, , but had arrived populated for single-channel only. All they needed was de-soldering a PCB DPST relay, replacing with DPDT, which should have never been otherwise - downloadable firmware and configurable software doing the real work, anyway.
Comical part was the Danish designer back in Silkeborg fussing over not being able to get the parts to me fast enough.
"Uhh Per? It's a stock JAPANESE relay. I'm IN Tokyo. I'll find them in Akihabera in about 20 minutes of slithering through narrow aisles 'tween tiny tables."
And did so. Also solder-sucker, wicking braid, good solder, and a VERY decent dual-temp iron.
Taipei has a similar "zone". Hong Kong as well.
Brunei? Not so much - you just have to fly in and out more often. Enough so the Security Chief invites you up to the top deck to watch some guy do "touch and goes" in a four-engined Airbus, of all things!
"Who would do touch and goes HERE at this airport, in a "heavy?" I ask.
He grins. "Our Sultan. He is upgrading his rating from his twin Airbus to his new one."
Shopping trips to London, he'd fly one, a former RAF crew the other one. That was so that not all his wives were on the same aircraft, and the Crown Prince was not on the same aircraft as his Dad flew.
Careful guy, the Sultan of Brunei. Also wealthy. Magical array of telco gear. Enough to run a country 20 times larger, and with 100% redundancy plus-plus, even so.
His dream? Another Zurich or London as financial hub. In Asia.
Otherwise, when the oil runs out, it is back to subsistence fishing for his people.
