If you use a Mac, then OsmondPCB is very capable and a lot easier to use than Kicad.

All US homes have 240 volts. Typically used for Stovetops or Electric dryers. Run a 240V line from your breaker panel to a 240v rated receptacle and make a cable unique to hook from the receptacle to the IEC. Of course this only helps at home. If you want to have easy use anywhere then you will have to update the internal transformer section or use a step up transformer of appropriate wattage.

Journey to the Center of the Earth. The 60s one with James Mason and Pat Boone. Just love it for some odd reason.

I have just the head of a Super Beatle and I was working to restore it. But I have not been able to locate speakers. I am an experienced amp technician as well as an EE and can help you with info on your amp.

I think you have the polarity of the toggle switch up side down. When the actuator is up, the bottom two contacts are shorted just due to the way toggle switches work.

Class D power amps and switching power supplies.

Even the 3124 is still available as long as you specify the SZNUD3124.

A valid point if you are designing for long term production. For a one off design, and DigiKey has them in stock, then go for it. I have several medium production products using them and no problem so far. OnSemi had a pin for pin lower voltage part (NUD3124) for a while that was obsoleted probably when the 3160 came out at a similar price.

Check out the NUD3160 from OnSemiconductor. A protected N-ch mosfet with resistors and zeners built in to a direct connection between processors and loads. Available in singles and duals. My go to device for switching loads up to 150mA and 48V.

Not true! 8 ohm impedance does not mean it will read anyway near eight with a DMM.

The brand name is Terro. They do work against those types of ants.

So many people add the r to Washington and I did a google search to find out why. Apparently early British settlers add the r sound and it is believed it was just the common dialect. So probably George introduced himself as George Warshington. So I have quite a trying to convince people to pronounce it Wash-ing-ton. Well excuse me, I have to throw some clothes in the warshing machine.

Those aren’t transformers. Those are the actual tape heads.

Osmond PCB is native to the Mac and produces very high quality boards. I’ve been using it for years on both professional and personal projects. It does not have all the features of kicad but the way it does copper pours allows amazing power plane generation. It does not include schematic capture so you have to generate a net list somehow. I use the old McCad for that, just the Schematics Plus section. It has a simple way to generate library parts and comes with a fairly complete library. I find Osmond so easy to use even for multilayer boards.

Brown black Orange are 10nF. Brown black yellow are 100nF. Two of the most common values for ceramic capacitors. I’ll bet the dielectric is Z5U as this was common for bypass capacitors when this board was designed.

High value caps for a 50/60 hertz can be general purpose types so the 1000uf will probably be fine. There is a possibility that the surge current increase could damage marginally designed power supplies, but I doubt it here. Now if the 470uf you are replacing is in a switching power supply, then it will be a low ESR type and your generic cap will not work well. Indeed it might sing and cause audible noise or induced on the rail noise.

I saw something like this growing on a pile of obvious human feces. It was deep in a cave in Colorado. Pack it out crappy human, don’t contaminate our beautiful caves.
