Very nice video. Thank you for your patient explanations and hard work!

Hi Dennis, good hearing from you and thank you for taking time to send me a uplifting message. I checked your KZbin channel, you do a great job yourself. You have some beautiful radios. Have a fantastic day. Regards, Jay

JZ, I have learned so much form you. You explain things so clear and effective that the new person without electronic background can understand and not get overwhelmed. I watched other KZbin channels and was so confused since their presentation is focused on individual with electronic background. Thank you so much for taking your valuable time making these videos.

[@RadioFixer]

I am happy and glad that you enjoy watching and learning. Thank you very much! I really appreciate your time taking time to send me such an uplifting comment. I am doing this as a hobby with no electronic background, trying my best to create detailed videos to encourage others without electronic background that are new to this hobby so they can understand and not get overwhelmed. So happy to know that is working for you. Have a good day! Regards, JZ

The wire that is wrapped around another wire but actually isn't going to anything is called a gimmick. It usually gives a small bit of capacitance ( to ground) about 5 or 6 pF. Basically for noise suppression in the wire it is wrapped around when tuned at certain frequencies otherwise you may hear a whine like noise when you tune to a certain frequency. We call this a notch filter in electronics. Zenith began using this damn rubber coated wiring in 1937 and was a cheaper subsitute for the cloth type wiring. Who knew that even 20 years later it would solidify and decompose. Zenith figured you probably would buy a new radio by then! Those fine pipe cleaners are great. Have a set myself. You are a meticulous restorer and don't want to make any mistakes. We should all strive to be so good at this kind of repair work. Thanks for the hard work you do my friend on making these videos!

Hi Steve, thank you so much for uplifting comments and being so supportive since I got started this channel. I have learned so much from you and want to take this opportunity to thank you my friend. You are a true gentleman. I get very nervous when someone with you knowledge watches my videos, since I have no electronic background and speaking second language. Hope you understand everything that I say in these videos. LOL As always is great hearing from you and wish you a great day. Best regards all the way from Jacksonville Florida, JZ aka Jay

@@RadioFixer You are doing just great for a self described amateur. Keep up the excellent work.

[@flywithbruce]

Incredible the amount of time to figure out this one issue. So happy it was all figured out. Excellent job!!

[@RadioFixer]

Hi Bruce, good hearing from you my friend. You are right, the darn thing is like a puzzle. It is fun to figure it out. 😂 Have a good day my friend.

That wire that is coiled on both sides is called a "mock capacitor". Somewhere the engineers must of figured that there needed to be just a minute amount of capacitance to enhance the circuit.

[@RadioFixer]

Hi Tony, thank you for letting me know. First I thought that manufacture forgot about soldering that wire.. LOL. I truly enjoy working on these radios. Was always fascinated with radios since was a child when we actually listened to radio shows as a family. Years ago before internet (LOL), went to public liberty and check out every book about subject to understand it better. As you know book knowledge is great but we need working knowledge and experience to be able to perform. As always is great hearing from you. Have a great day my friend!

I buy a lot of my parts from Just Radios in Canada they always been good to me. Jay don't cut the red wire Oh wait sorry about that I was thinking of the bomb squad disarming a bomb lol Yes those cat eye or tuning eye tubes are a bit different to wire up. Obviously you did a great job jay it's working. Thanks for sharing.

[@RadioFixer]

Hi larry, you made me laugh. Thank you for That! I am start working on the car and man is getting harder to get in and out of the car. I think the car shrunk the last a few years, YES that what happend.. LOL Have a great day my friend.

Great video J. I’ve heard that the ‘X’ plate 6X5 tubes are better constructed tubes than the standard coke bottle types, so they don’t short like the G type tubes. Yep, that 1Meg resistor is a tussle. 😊

[@RadioFixer]

Hi Jim, you are correct. All my research indicated that 6X5WG is better then 6X5G. I like the style of G model since they so unique design as you said like a coke bottle. Just want to make sure do everything that I can with this radio so our older daughter and granddaughter can enjoy it for many years and remember me by it. I have 3 children’s and I like each of them have a floor model radio. As always, is so good hearing from you and thank you for being in touch. Have a fantastic day Jim! Regards, Jay

Deoxit is the goto cleaner for switch contacts, connectors and tube pins and sockets.

[@RadioFixer]

James, you are correct. I have used Deoxit for switches, contacts and very happy with it. Since we live in Florida the humanity is so high most radios tube connections and pins are corded and not having a good connections so I used the other product for that since it works very well in high hummanty. Have a great success using it on my cars that I restored and in process of restoring. Good hearing from you, thank you for reaching out and sending message. Regards, JZ

[@jimnewman5596]

Great job fixing the cat eye. Was the 1 meg open or out of tolerance?

[@RadioFixer]

Hi Jim, thank you very much my friend. The resistor was way off almost 3 times higher. The eye tube was very weak/bad, I am glad that I had one which I bought years ago. LOL. Thank you for reaching out Jim. Have a great day!

[@James_Bowie]

At 14:13, I believe you mean to say that pin 3 is the Grid.

[@RadioFixer]

Hi James, thank you for bringing this to my attention. You are a true gentleman. I truly appreciate you experience and wish that I had electronic background or mentor like you when I got started. Was always fascinated with radios since was a child when we actually listened to radio shows as a family. Years ago before internet (LOL), went to public liberty and check out every book about the subject to understand it better. As you know book knowledge is great but I needed working knowledge and experience to be able to perform. Every radio I learn more and more. Have a good day! Regards, JZ
