Nick, Re I still hear people say "220" when they mean 240V. How do you know which they mean? Right here the laws for 240 Vs 220 are simple, but complicated. You put 240V 0r 120 into your long

NickThere are many who feel as you do.?? I would check the tube heater voltage at the tube socket.? If it is within 10% of 6.3 volts then all is OK according to the vacuum tube manuals.? I am of

I always use a variac on my vintage gear set to about 115V to keep the filaments safe.? My line V is about 121/242 but at a previous residence it was sitting around 108V! I still hear people say

Depends on the year!? Sometime in the 1950's, the line voltage convention was changed from 117 to 120 so the choices were 117 / 234 then and 120 / 240 now.? 115 volts was proposed in 1927 in the

Another reason (other than the transmission losses) to use HVDC transmission lines is to be able to sync together (at 50 or 60 Hz) various parts of the power grids. The power provided by Hydro

Is it "220" or "240"?

Donald"Now gone?" that's really funny!? Even professional electricians still call it the "Edison three wire system."? See:?https://www.youtube.com/watch?v=yl35KT64g2g Might as well to try to

Good luck with the S-20R, they are actually good receivers. I bought one, supposedly restored, several years ago and found that while it worked the restorer had done a pretty crude job, so it did

A fascinating list, I didn't realize there were so many. Many years ago I went on a tour given of the Sylmar station of the Pacific Intertie. It was fascinating. It looked like the set for a very

Let’s try to make peace with AC and DC power this way -- Low voltage DC transmission is impractical. High voltage DC transmission works great since there is no “Crest Factor” to deal with. In

DonaldYou are mistaken.? See:??https://en.wikipedia.org/wiki/List_of_HVDC_projectsfor a very long list of existing HVDC transmission projects.Regards,JimLogic: Method used to arrive at the wrong

Long range DC distribution is not practical as we have proven many times over Under the Edison system EVERY block in New York had to have its own generator as running the DC more than a block was to

Just pointing out that is it no longer called the Edison system Any relation to Edison is now gone so stop calling it that The only Edison we have kept is his light bulb screw and it

No, I read it correctly.? You are proposing a distinction without a difference.? The Edison system was developed to reduce the number of conductors and the cost in a power distribution system, a

Hi Jim, I would copy what I see on Wiki-p , but I will just mention that I see some critical punctuation in there. Others should look for themselves. Sent: Friday, January 10, 2025 10:25 AM To:

Welcome, Tom.? I'm also new to this forum.? I've been a ham for 30+ years now and in the past several years have gotten into vintage receivers and transmitters.? I hope saying this doesn't get me
