Re: Another new member -- intro
All I can suggest is to look for any wiring errors you may have made. it IS possible for a new part to be defective but its rare. Just should not be forgotten. If the LO doesn't work on all bands

Re: Another new member -- intro
I echo the sentiment, best looking SX-23.
So I put in a place of honor on the front page.

Re: Another new member -- intro
Thank you Richard, Paul and Nick. Yes, I've read that the S-20R is a pretty decent receiver and worth repairing/restoring. I passed on the Hayseed Hamfest can electrolytic and just used discrete caps

Re: Power distribution, was: 2-wire, unpolarized outlet ?
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

Re: Power distribution, was: 2-wire, unpolarized outlet ?
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!

Re: Power distribution, was: 2-wire, unpolarized outlet ?
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

Re: Power distribution, was: 2-wire, unpolarized outlet ?
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

Re: Another new member -- intro
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

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
