Echophone EC-1 Tube Radio Restoration with Alignment Procedure

I just unpacked one identical to this one that my late Dad restored not long before he passed. It works wonderfully, but I think I’m just going to primarily display it. I learned so much watching this video, and appreciate the amount knowledge and skill it takes to properly restore these historic radios! My Dad was an amazing electronics tech, and you are, as well! I think it is a dying art, and I’m glad to see that you are not only carrying it on, but sharing your wealth of knowledge with these excellent presentations!

Wish I could see where you are on the schematic. I would have thought those 'cans' were inductors.
--later--If I would have been patient I would have seen the schematic. Yup, caps across the inductor. Now I wonder why they didn't use a slugged inductor and you could just twist on that and it would have been very stable. Did they not have those back then? Isn't having vari caps less stable? Scares me that the filaments are all in a string right off the mains. Yikes.

What did I wake up to

I noticed the Knight unit use to test this rec'vr. I did buy some Knight kits and put them together. One was a tube tester. Not fancy model but big enough to get the job done. I also bought some Heath kit units.

Hi new to your channel , and i think it`s awesome .
I am a novice in electronics and most of it goes over my head, but very interesting all the same.
Brilliant channel iv`e got some catching up to do . All the best Stu (Newcastle uk)

Wow, my first SW Radio when I was a Dumb Teenager! It started off my life into Ham Radio and getting a Commercial FCC license, and 36 years repairing Communications equipment. I spent many hours listening to that Bull on something called "Ham Bands".

uh do you work for nasa cuz damn

Thanks for the content.
Keep up the good work.

Capacitor Octopus.. LoL..👈🤣👉📻

Cool, I read where these radios were ued to "enhance Moral" in the field during the second world war. Saw one on Ebay today for 50 bucks that looks like it was found in a trench in France. What a mess plus 32 bucks to ship. It was a 1A model.

Thank you for the Video. I am hoping you can answer a few questions for me. I am attempting to restore a 1930s era tube radio. I am stuck on the IF portion (working backwards). I have a cheap signal generator and can hear a speaker tone to the IF section. I get no static, sound, nothing from the radio. I KNOW it is very out of alignment. I was thinking about picking up a cheap usb oscilloscope to see if I can figure out what's going on with the IF (I get no capacitance readings on the trimmers) and possible align the radio. I am an electronics neophyte. I was wondering if a Hantec 6022be would work. Based on my understanding, it is a 20mhz scope with 5 v max line input. The radio generates 320 V DC. The IF is at 465 KHZ, the alignment procedures call for up to 1.6 MHZ signal for the short wave band.

Would the 6022be meet my needs? If I used a 100x probe, would the scope and PC be protected?
Thanks for your input.

Mr Carlson my hobbys are painting pictures and lisining to shortwave and ssb iam thinking about getting my ham license I have 4 shortwave receivers

Mr Carlson me and my cousin are going to a Swap meet in September 11 Sunday morning at 8 am in Milwaukee 2022

Mr Carlson you are good at electronics restoration and alignment

Mr Carlson your vintage Echophone EC 1 shortwave with ssb is cool

Mr Carlson I like your utube videos are awesome

Mr Carlson the radio chassis is in good shape it looks like new

Mr Carlson the radio cabinet looks like new

Mr Carlson you are good at electronics restoration of vintage shortwave radio Receivers and Alignment

Mr Carlson your vintage Echophone EC 1 tube shortwave radio Receiver from 1940 is cool

Mr Carlson the radio chassis looks like new that's so awesome

Mr Carlson the radio cabinet looks like new that's so awesome

Mr Carlson you have instresing information on electronics

Prague to find a nice old radio to play with that and get my old Dx100 out and get a heat sink on the transistor that makes it drift so much.

Is it possible to use an inverter powered from a car battery, instead of an isolation transformer?

Some of what you describe as "computer generated noise" is actually radio teletype or digital shortwave data transmissions. The "galloping horses" sound is probably fax transmissions use for sending things like weather satellite or weather maps to ships at sea. These can be decoded by using the BFO and feeding the audio into a decoding or other computer-assisted software.

WOW!!!! This is BY FAR my FAVORITE video of yours!!! You have answered so many of my questions. I now know what "loosely coupled" is and WHY it is needed. I know how and where to inject signals and why, and I now understand what the negative voltage does in the AVC section. I have self taught my way thru WW 2 military repair manuals for several types of WW 2 radio sets and, frankly, I'm surprised I did as well as I have in restoring those radios. Much of what I didn't quite get in those manuals I learned by logical trial and error. Just figuring out what outcome I was looking for and working out way to get it done. I hade a good vintage VTVM and vintage signal generator as well as a modern digital signal meter and field strength meter. But with what you have taught me here I now know I could have done better. THANK YOU.😎

Some singles 50 KHz 2.5 5 10 15 20 & 25 MHz WWV, WWVB & WWVH

i have two of these and many sibling Halicrafters branded models. S-38 is my favourite and 5R100A excells in perfomance.

Another interesting thing you could do is show where an antenna tuner could be added and maybe also where a "S" meter circuit could be added

excellent explanations.
Thanks for uploading!
Now I'm hooked to your channel 200% 😄 !!!

2 hours in roughly : No padding condenser on this band on your document for Band 3: is that the one with the missing clip instead of being the one you said had Band 1 in the Alignment procedure ?

Kind of an AA5 in a heavy duty case. If it had a power transformer it would have been nice, but a really neat set. Really too well built to have skipped the power transformer...guess it was a cost consideration.

why the f... you have a russian soldering gun ?

Hi I’m Julian Crippen

Mrister Carlsons lab your utube videos are awesome my friend you do good work 👏 🙌 👍 👌 😀 😄

Could you tell me what the 7.5k resistor on the output transformers purpose is? Apparently someone had removed the one on my EC-1 radio, but I don’t hear much difference in the operation when I hook it into the circuit. Thanks for all the great videos!

Hi, I am interested in learning about the electronics. Please add the cc in English in the video. Thank you.

What is an "absolute value fuse"? I've never heard that terminology before, and a web search finds nothing.....

Ok, I have to know, since I have mosfets on my mind, would it be possible to build a vtvm using mosfets? And what would the differences be?

Gotta give these folks back in the 30;40 and prior a lot of credit pretty ingenious.

I wish I would have had the knowledge I'm learning now back in 1965 when I was 15 and built my Knight Kit Star Roamer. It worked well when I was done but really didn't know how it actually worked. Mr. Carlson really opens your electronic eyes.
