The Blue one is polarised. That type has a small permanent magnet to make them more sensitive. It also means the drop out voltage is very low. I've tested 24V examples that held in down to 3V. You have to be careful of sneak paths when the drop out is that low.
This I knew.
1.) it has the proper symbol for that
2.) I know those series.
Regarding the 'Relay battle', I was referring to the 'Centigrid' type (visible in the upper right), respectively a RF optimised variant of them.
Centigrid are nice, very expensive though. Funnily enough yesterday I found a PCB from a 2" aircraft indicator I designed in about 1995. It has a centigrid on it.
Virtual cookie to anyone who can identify the aircraft type
G'd Day,
let me guess after I have taken a closer look with my thick glasses: That's for the F22 fighter airplane as visible in the copper mask in the lower left corner?
If that's correct - where can I get that cookie then, please?
Cheers,

Close, but no Cookie.
It's F20 not F22. Not a fighter but has the wing from fighter. French to boot.
Aircraft in the photo has at least one of the PCB's on board, possibly 2 depending on role configuration.
Very nice Med, but there is not a single glowing Tek in sight, so what started your love affair off with them?
I always wanted them but back then even the tube scopes were still in high demand and too expensive.
Took over an hour to start the snowblower. Carburator must have been partially gummed up. Yes, there was some fuel so it did not dry out to a hard varnish during storage. Yes, there was stabilizer in the fuel. Yes, it was high octane fuel with no ethanol. Tank was mostly filled with new winter fuel purchased this month.
Not much later, the snowblower found the stick that the dog had been playing with. Okay, actually a 3" diameter firewood log. Yes, shear pins work. It is a PITA to replace a shear pin, especially outside far from the garage.
Finished snow clearing at 9:51pm, then still had to walk the dog...
Now time for
Is it a Tecumseh "Snow King" engine? If yes I pity you. There's a reason they went under and out of business. Their carbs were total crap and even pampered the passages would clog up with the result you experienced.
It looks like you might be bang on. It is a Sears Craftsman with a Tecumseh engine...
So I can assume I did nothing wrong, but I can assume that when I get sufficiently frustrated I will be blowing (pun not intented, but left anyways) the TEA budget on a snowblower.
Naaahhh... just get a cheap Chinese carb off slAmazon, and install a fuel petcock if it doesn't already have one. Use it religiously.

Once you have the thing running again with the cheap Chinesium, then you can worry about rebuilding the original for a spare. Or put it off til summer.
The later models of Tecumsehs... the engine itself is pretty good, but like med says... carb and coil were contract-built by the lowest bidder, so tended to be somewhat hit or miss for durability.
Briggs have their own constellation of problems, not the least of which is chronic blow-by due to oil rings made of case-hardened cheese; replacing a mostly functioning snowblower for the sake of "the brand" is just ¢-wise and £-foolish.
good hunting!

I replaced the Tecumseh engine on mine with a Harbor Freight "Honda Clone" engine, the best thing I ever did! - smooth, powerful, quiet, economical with fuel...
Still, I love the 5hp Briggs on my leaf blower (probably 30 years old). Starts first time every time, doesn't burn oil, runs like a champ, sounds mean!

Yes, I've heard that the Chinese Freight clone engines are actually quite good but I have no direct experience with them. Another reason Tecumseh went bust.
Go easy on our Ozzie member.
Matched 12AU6's installed in Type CA plug-in which is in turn installed in the Type 535A. 45 minute warm up. DC Balance: Perfect!
Solartron 7055 on the bench. Restarts continuously. Also smells something fierce when warming up. So, naturally I dug up my bag of replacement Schaeffners and opened her up. Much to my surprise, the filter is in one piece. But...
This kindof got lost in all the "discussion" I started over my own little bit of electrical fustercluckery... what was the eventual outcome?
Hard to tell from the angle the vid was taken at; looks like a safety cap from here, but given the circuit more likely a blob tant...?

9. Capacitors are Murphy's footsoldiers.
Doing it in a lab like in the video is easy-peasy. Try doing it lying on your back in half-darkness and freezing cold inside a cramped sarel box, and see how easy it is.[/color][/size][/b]
Oh, of course. The demo is not the install.
It's just that once you've got the wire into the hole, pressing the "connect" button is going to be a bit easier than finding the hex key, tightening lightly, swapping to the torque wrench, getting it to grab, and then torquing to spec. All the other parts are roughly equal in shittyness for all cases.
And I thought tants were expensive. This is almost $60 USD of HV disc ceramic capacitors to re-cap one HV supply in the two Type 547's. But at least now I can start experimenting with the HV issues.
The latest from the clowns at hvstuff.com: An inquiry was sent via PayPal to respond to me with status of the order. If no response by tomorrow I can authorize PayPal to release the hounds and get my money back.
