There's just one word to describe Buddy's repair ability - he's simply an artisan. Wow, just never ceases to amaze me with the magic he can do! 73 - Dino KL0S

[@TheRadioShop]

Thank you for those very kind words Dino.

[@vener6]

Nice fix ! This receiver will hopefully be enjoyed for several years now. 73!

[@RapperBC]

That audio was the *perfect* intro.

[@w6by]

An amazing piece of work, and excellent close in photography.

[@cfcreative1]

I love the simplicity of these radios.

[@mitchelrowe7363]

My uncle gave me my SX-42 when I was 14 years old. I am 55 now. Thats 41 years of ownership! I still use it once in a while and plan to do a full restoration and post it on youtube someday. Maybe this summer.(Yes I will after my birthday it will be 42 years celebration) The SX-42 has the best audio of any receiver I have ever owned bar none. It is the 6v6 audio coupled with the infinite impedance detector. Thank You Uncle Bob!

Buddy does amazing work .he great to learn from

[@michaelmatthews1287]

Hello to the radio shop sir as always I appreciate viewing your videos I learn something every time awesome restore work I like how you pay particular attention to the mynute details your Innovative work goes beyond most tec's they would be at a loss very nice work sir excellent again thank you for what you do sir.

[@TheRadioShop]

Thank you Michael. I try my best to explain things in simple ways. Plus there seems to be lots of good techs that have dropped off KZbin so want to give the best I can,

[@tubeDude48]

At 9:30, towards to middle-right side, it looks like a totally burnt resistor. *EXCELLENT!* The hardware repair on the main shaft was most informative.

[@TheRadioShop]

I thought the same but it is a low ohm resistor and covered in wax. Thanks

[@alpcns]

Thanks for the video, Buddy - as always, a genuine pleasure. What you can do with a bunch of crusty old gears never ceases to amaze me.

[@TheRadioShop]

Thanks for the kind words my friend.

[@LarryDeSilva64]

Hi Buddy I have that receivers newer brother a hallicrafters SX43> I bought mine at Ham and HiFi for the giveaway price of $20 along with a hallicrafters SX101 for $40. Both needed Minimal work to get to recieve again. Always great to see you fixing these old receivers up. Good work around to get that gear drive to move without slipping. Mine wasn't used as much so the gears seem fine.

[@TheRadioShop]

Nice deal on the rigs! Cannot beat that. Glad to hear your gears are good. I have seen many missing the parts. Thanks for stopping in.

[@majordisappointment8692]

Thanks a well built radio nice i hope they do go full restoration would be a great piece for late night SWL.

[@ArthurJS123]

Thrilled to see one of these bad boys on your bench. Mine went through an extensive 1 year electronic and cosmetic restoration. Check the radio out on my channel- it’s a true family heirloom.

[@dbingamon]

I have one of these, I've just changed out almost every capacitor. I have have to do the can cap in back still. My has one of small gears cracked in the tuning. It will still mesh up but spins on the shaft when it is not supposed to. I'm thinking of binding it with JB weld but after I've seen your resistor lead through a tiny hole idea, I really like that and might pin it that way instead. Mine also has rust around that friction mechanism. Those wavy washers, called Bellville washers are still available, we use them at work for packing nuts on mechanical valves. Also, that locking knob in the front is missing on mine, I will have to make something.

[@Joe-KN4IFI]

Great work Buddy. You are a true craftsman. Love watching your videos. I learn so much. 73s Joe

[@TheRadioShop]

Thank you for the kind words Joe

[@bblod4896]

At 27:37... When you turn the shafts, you can see a tiny bit of wobble at the rear of the shaft. Nice rebuild. Thanks for the lesson Buddy.

[@TheRadioShop]

Yep, thing is old. And worn out lol Thanks B

[@michaelellard4664]

Really enjoying the video. Must have great skill ans patience.

[@TheRadioShop]

Thanks

[@b3j8]

Such a cool old radio! Looks like the rig was either used/stored in the basement and exposed to dampness. You know know your craft sir. Very good instructional video!

[@lylewatts6370]

I must say a lot of mechanical parts in these old radios.They are worth fixing in my opinion. Great job Buddy! I have a CR-91 RCA to go through when I have time. Love this old stuff.

[@TheRadioShop]

Thanks Lyle, and so do I. Old stuff is fun. Good luck on the CR-91

[@CraneofBoulogne]

That is a great video! It is nice to see a professional ply his trade.

[@jaybats7865]

Great job Buddy. Your expertise never ceases to amaze me. Thanks for the fun.

[@laceradewilde4056]

The most precious asset about Buddy's work for me is he works on things I also own. I dont own a Mustang so the transmission refurb made me yawn. I do like 'em Mopars though. But I digress. I do have a Halicrafters SR400 that needs your magic and I would love to watch a video of the repairs. I left a message on the Electronic Universe site about it. Sadly, there doesn't seem to be much activity so I raided the fridge and lit the fireplace. Oh and spray painted the front door Mary Popins Pink. Love your videos, love your work. Your blessed with a wonderful gift. I'll be watching. Have fun!! 73's Lacey K4LCY

[@TheRadioShop]

Thanks. No that is one rig I have not worked on in a long time. I will look for the message. . Thanks again Lacey

[@TheRadioShop]

Thanks Frank. Yes it is a masterpiece in itself!

[@peterharband326]

Nice old receiver Buddy. Had a SX 24 when I was a kid. Did a dial string job on a Drake 2b a few years ago. Tough job but was worth it. Good to see u back on deck.

[@TheRadioShop]

Thanks Peter. They are pretty tough old rigs. Dial strings? No problem :-)

[@donaldshields2483]

Very nice job you sure I have a lot of patience and usually very very good work I wished I lived close by I have a Kenwood 570 I’d like to have you check out but I’m up here in Maine and I think you’re in the Carolinas of a Julio so I think I will pass seven threes God bless

[@jenniferlachance351]

Hi Buddy. I've been looking forward to this video since you had shared your plans to overhaul the tuning mechanism sometime back. You didn't disappoint! Thank you for sharing! I have a SX-42 that belonged to my uncle (long since an SK). I plan to restore it this summer. It is in pretty good shape and has always been in clean air conditioned space. I hope it is as clean on the inside as it is on the outside! 73 and thanks again!

[@TheRadioShop]

Good luck on the repair. These are pretty easy to work on. Lots of room. Sorry it took so long to get it uploaded as the video was recorded first of December.

[@n8nkqrp595]

'Radio shack, Bill speaking. May I help you?' "I sure hope so, Bill. I lost my catalog. Could you tell me if you guys stock brake shoes for an SX-42?"

[@edwatts9890]

"Uhh... ...Have you tried Auto Zone? We just have cell phones!"

[@MrVasile]

Great video, Buddy. I always learn something new, and am always amazed at your knowledge! Hope you are feeling well, and looking forward to the next one! 73, Tony, KB9A

[@TheRadioShop]

Thanks Tony. Feeling a lot better. This video was recorded before I became ill.

Thanks.

Shear pin. Clever fix Buddy!

Thanks Richie. And if it ever shears off the bits fall on the chassis so no shorts.

[@scottlee1211]

Another great video! Thanks Buddy for posting!

[@TheRadioShop]

Thanks Scott.

[@ArthurJS123]

I had mine, which my late father bought brand new, and gave to me, professionally restored four years ago. What did your customer decide on cosmetics? It seemed to me it wouldn’t take that much. My control panel was stripped, repainted, and silk screened. It was expensive, but worth it. If they wanted to do a more basic restoration, I believe Radio Daze sells decals for both the radio and the matching R42 Reproducer. You do great work.

[@ignacioleon8249]

Good nigth exellent job Buddy who knows ?knowos Looking good

[@TheRadioShop]

Thanks

[@ignacioleon8249]

Hello, thanks for repling back to me. I have a question i have two radios yaesu ft101B they do not work, No T X but it does receive. Would you be able to fix them?

[@pda49184]

Great piece of work Buddy.. I witnessed a very similar type receiver being unpacked from a shipping box..📦. Amazingly the whole outer casing was bent about 15 degrees from true.. I speculated for some time to figure how the courier had achieved this feat of mental bending .. I can only assume he's dropped it from a 4 story building or driven his truck over it. The one in your shop would be classed as a 'light' restoration in comparison, but I feel blessed I don't have to do either 📻...

[@waynethompson8416]

Have you ever tried cleaning contacts like those with Q-Tips and Tarn-X before? I have never used it myself, but watched someone else do so and was amazed at how clean they became.

[@TheRadioShop]

Yes that stuff works wonders. Just make sure you are in a well ventilated area.

[@catman581]

Great video, I didn't go through all that work on mine, I just put a little 2 part epoxy on it, it works like a charm. Not original, but a good fix

[@TheRadioShop]

Thanks Richard. And that works also.

[@catman581]

@@TheRadioShop You fixed it the right way. I don't have the dexterity anymore to do that kind of work, so I had to take the easy way out. I really enjoy your videos. Regards, Richard Sacco AB3IY

[@xraytonyb]

HI Buddy. Happy belated New Year to you as well! Thank you fro sharing! I have one of these units waiting (over a year) to go on the bench. It's almost mint and includes the R-42 speaker in mint condition as well. The band spread knob looks to be OK on mine. The person who I got it from was an old time Elmer and he had it restored by someone who was supposedly an expert on these. I haven't opened it up or tried it out yet, but your video is making me want to move it up on the list! Great job as always! Looking forward to your next video! - Tony

[@TheRadioShop]

Hi Tony and great to see you. Cool deal on the rig. You will find it fun to work on. Those band spread knobs are the first to go in these. Specially if it has any time on it. You see a lot of them even missing the knob or the shaft broken. Waiting to see yours on the bench. Thanks for stopping in.

Hi Buddy, have you heard from Mike or Peter? I have not watched your video yet but if history repeats , it will be wonderful. Thank you!

[@dl7majstefan753]

Very good work again! I don´t understand the behavior of the S-meter: At 49:45 it indicates S9 plus 40dB with no signal - missed i something?

[@TheRadioShop]

Thanks Stefan. Nope you did not miss anything. That is the line noise in my area. Some days it is real bad. I have two solar farms near by.

[@dl7majstefan753]

@@TheRadioShop Ha! I thought, solar farms are there to protect our environment - and now they produce a lot of electronic pollution!

[@984francis]

I think the brake material caused that rust. In fact, it may be the worn material, not rust. It has to go somewhere.

[@gbowne1]

I'd happily make whatever parts needed, even sheet metal/brackets as a donation.. just let me know.

[@TheRadioShop]

Thank you very much

[@gbowne1]

@@TheRadioShop You're welcome Buddy, just let me know. I was actually considering making those "NLA" unobtanioum small parts and sheetmetal/chassis/brackets available for restorers, especially for Johnson, National, Hallicrafters, Heathkit, etc. All I need are drawings or sample parts.
