Jon, It's from the relay in the amp. I would not know how to convert it. The amp is made to pair with a Gonset transceiver. I have since sold the unit, since I could not make it work for me. I bought it to save it from the scrap heap. Thanks for viewing! 73 Paul AA1SU

@@vtradio thanks for saving it from the scrap heap! I guess I'll have to look around and find a second amp on a scrap heap somewhere :) I imagine the main difference is the big tuning coil, and whatever capacitor it's in resonance with.

@@vtradio part of why I was asking, was that the relay may get worn out quickly from doing CW with it. I'm interested in learning code, and looking at possibilities for simple rigs to use. I'm guessing I'll have to build something, which is more than half the fun :)

My pleasure 😊

Thanks for the nice comment! 73 Paul AA1SU

Thanks for the ideas. I will try them out when I get a chance. I've been trying to sell this at a local Hamfest w/o any luck. However, now I'm going to keep it for a vintage AM station because someone wants to buy my Hallicrafters SX-101A that I was saving for that purpose. 73 Paul AA1SU

I have the NC-300 and recently sold a NC-303 with matching speaker. I want to sell the NC-300, but not having much luck at the same Hamfest where I sold the NC-303. I have a really nice Hallicrafters SX-101A that I am keeping for the vintage AM station that I promised myself I would put together a few years ago. I have videos of all 3 here on UA-cam. Check then out when you get a chance.

I did not know this had a selenium rectifier. I made no repairs or mods to it. Soon after this video, I sold it on eBay. I rescued it from the estate of a Silent Key. He was a ham radio hoarder. I bought as much stuff as I could before the house was sold. I went by the house a few months ago, and it had been completely renovated. I knocked on the door to find out what happened to what was left behind, but no one was home. However, I and some others saved as much ham radio history as we could over a 2 year period. Thanks for watching and writing. 73 Paul AA1SU

Thank you for watching and commenting.

Actually, I sold it to Todd Bigelow KA1KAQ. He used to live here in New England but now lives in VA. I think it sold for $75. I was glad to see it go to a good home. He said that he had one already, but that mine looked in better shape, so he planned to use that one. Have not followed up, though.

Aha! Good catch. I did not grow up with these, like you did. You can correct my mistakes when you make a video of it. I actually made the video clips in Sept 2022. Just got around to uploading it. I replaced 3 capacitors and 3 resistors, using the Hayseed Hamfest kit. When I first got it, I thought something was wrong because it would not transmit w/o the key. But after I replaced the components, it still did not TX. Then, one day it suddenly did. You said that I probably bumped something that fixed it. I also replaced the resistor in the parasitic choke because it broke apart on me. That may have also taken out the 6DQ6A tube because I replaced that, too. 73 Paul AA1SU

@@vtradio Do you go around replacing light bulbs that might go out? I had a capacitor in a S-76 receiver blow up and belch smoke and then stop and the receiver now works fine.

I had one of these as a novice in 1958-brings back a lot of great memories! Used it later to drive an amp to 500 watts….

I know. I missed two of them by one second.

How true, how true my friend.

Thank you for your insight.

Yes, if you set it next to your computer sound card. Did you like my picture of Brother Stair at 6:16?

Pat, Actually, the coax connector is factory installed. I probably won't add the resistor, but who knows, I might. I've decided to keep the radio in case ever get around to building my vintage station. I had planned on using my Hallicrafters SX-42, but the SX-101A is Ham Band only and would probably be a better choice. 73 Paul AA1SU

No Jamie, it only covers 143.8 to 148.2 MHz. It is 2 Meters only: no 11 Meters. Thank you for asking. 73 Paul AA1SU

On/Off button is still a mystery to me. I did not hear about NEAR-Fest, so I just went to the web site. I see that it is Friday only and ends at 3 PM. I'm horrified! I'm glad that you mentioned it to me. Thank you.

@@vtradio The Deerfield fair treats Nearfest like the ARRL treats their members.

@@vtradio It's now Thurs & Fri

@@SSJIndy Yes, I heard. Not sure if I can break away on Thursday. ☹

The fact that you are receiving the AM Broadcast Band is a very good sign. What I would do for starters is to go to a room, away from computers (or outside), and extend the wave rod (antenna) all the way up. If it's daytime, alternate between the top 4 bands and tune around the dial slowly. If it's nighttime, try the bottom two bands. You should be able to tune something in. Yes, this radio will accept an external antenna. Open up the back and you will see two screws near the bottom of the wave rod. You can attach a long wire to the one marked 'A'. The other one is marked 'G' for ground. Don't worry too much about that one. If you want to see the video series that I did on restoring this radio, go to my channel and click on Playlists. It will probably be more that you want to get in to, but it may give you some ideas of what to look for. If you know someone with a tube tester, you may want to start by checking those (baby steps). Installing the Filt-R-Pak from eBay would be a plus, too. I just checked and the seller is running low on stock. I need to order one each for my 8G005 and my H500. Good Luck and keep me posted. 73 Paul AA1SU

@vtradio Thank you for your suggestions, Sir. Here's my setup. ua-cam.com/video/TwdrXaBCZJE/v-deo.htmlsi=9badqcOiyo9E5CTB The SW now works great with my external Hustler HF all band vertical. 31-meter band is my favorite and, of course, it is best to listen to it at night. Here, in California, I am able to pick up Radio España daily on 9.690 MHz starting around 22:00 UTC (around 2 PM Pacific). And, yes, the radio hates all modern electronics and LED lighting, so I had to setup a normal incandescent lighting in my bedroom because I love falling asleep while listening to a SW broadcast with a little bit of static noise. Although, I don't speak any other languages besides English and my native Russian, I still enjoy listening to broadcasts no matter what language they are in. I am a bit disappointed about the lack of European stations that can be heard on SW bands at my QTH but there is a station from. Miami that broadcasts European radio shows. 73!

It is a handsome looking radio, isn't it!

Thank you. I'm trying to learn more about the tube transmitters. I've already restored several tube receivers.

Dave, Good luck with your recapping of your Zenith!

Yes, they are 1/2 watt resistors. I don't think I measured the old ones at the time.

Ha Ha! That's great.

You can do some sort of internal grounding trick to keep the thing from spewing out harmonics on higher HF frequencies and possibly 6 meters. Otherwise the Knight (T-) 50 is a simple MOPA CW transmitter, and I've heard people really like them.

I think I read that somewhere. Thanks.

That's great. Does it work?

@@vtradio yes…..along with my 1934 Philco….

@@vtradio yes. I listen to it every day

No kidding. That's interesting. I think there are specs to build on the web somewhere.

I don't have the radio anymore. I would think that there would be a way to remove the memories. If not, you can add popular simplex frequencies in there. Thanks for the kind words, too. 73 Paul AA1SU

Thank you! I'm sure that you will enjoy the radio. 73 Paul AA1SU

Steve, I agree. In part 2, I changed the settings quite a bit, and it was more pleasurable to use. I was not used to it yet, and I jumped right into making the video. 73 Paul AA1SU

Rick, That's great! Happy to help. 73 Paul AA1SU

Thanks. I got mine in an estate sale, too. I couldn't really find a use for it here. A friend wanted it, so he traded me a non-working 1939 Hallicrafters S-20 Sky Champion Shortwave Receiver. Not sure who got the better deal. 😉😉 73 Paul AA1SU

Eddie, I really like the tube receivers, too. I also have a Sony ICF-2010 but I haven't really listened to it since I bought it last year. As for the S-120, I sold it soon after Part 2 came out. I sold it a Hamfest to a nice older couple that looked at it one day one, thought about it overnight, and came back to buy it on day two. I'm glad it went to a nice home. 73 Paul AA1SU

Thanks Craig. That's good to know. 73 Paul AA1SU

Yes, I believe that a modern headphone will work just fine with a stereo to mono adapter. I have not played with the tone controls too much. As I recall, they make a difference, but not a whole lot. Thanks for the question. 73 Paul AA1SU

@@vtradio Subtle differences in tone is what seems to be the common response... I'm asking because I can't hear any difference at all with my ZTO R600. The tone is fine as it is, but I'd like to get those tone switches working. Thanks for responding... 73

Bob, I forget exactly where, but this link looks like the exact thing that I used: bama.edebris.com/manuals/zenith/l600 It's for the L600, but there were very few differences in the 600 line. 73 Paul AA1SU

I made an email request for a quote on just the caps w/o the can capacitor. He replied right away. It turned out that I did not need the single electrolytic capacitor. I have since misplaced it. Bummer, because I have other T-Os that would benefit from it. Thanks for your comment. 73 Paul AA1SU

@@vtradio I sent the radio to TOMS OLD RADIOS in Texas. He restores these radios and will replace whatever is necessary to repair. TOMS OLD RADIOS is the company that makes the Filt R Pak power supply

@@adriancressy8363 Adrian, Great option! I've seen his restorations on eBay. He does wonderful work. Much better than mine.

You may have to go thru it, like I did. These are very old radios. Good Luck. Le me know how you make out. 73 Paul AA1SU

Roger that, good buddy!

FILM? Did I say film? Oh well, we all make narrating mistakes. 73 Paul AA1SU

Thanks for subscribing! I have a lot of radios to make videos of, but see, to want to operate more. 73 Paul AA1SU

Thanks for watching and thanks for the comment. It does look hard, doesn't it? I would have to watch it again before attempting it on another radio, which I plan to do. How's that Globe Scout coming along?

@@vtradio It looks impossible for me. You are a genius. It would-be easier to fix the Globe Scout without a schematic than restring this.

@@K1OIK Thanks. I will admit that I was terrified to this, or the caps for many years. I left it up to a guy that I met at NEAR-Fest to do it for me. In the end, I replaced more capacitors than he did. I have since sold this R600 but kept my first one. 73 Paul AA1SU

I have one this on my garage. Not sure if work. The only thing I know it's very heavy.

@@bolacheia9444 You should get it out, hook up a wire to it and see if it receives that AM Broadcast band. 73 Paul AA1SU

Thank you for the comment. It could be that I was looking at the wrong part of the schematic. All the other research showed a resistor to bring down the voltage. I sold it at a Hamfest soon after this to a nice older couple. I could have sold it for more on eBay, but I'm happy that it went to a good home.

All I bought was an Eton AM/FM/WX for a buck. I showed great restraint this time.

Thanks for the comment Danny!

Brian, thanks for the comment. Good luck with your Vette. Mine is still not back together from the heater core replacement last fall.

I'm not sure. I was under the impression that only the electrolytics mattered for polarity. How do I tell the foil side?
