Mike, I wish this series of videos were around when I rebuilt my DX-60B a few years ago. I have a stupid question, when you’re checking the values of resistors and capacitors, are you removing them to test or can they be done inline? 73 Lloyd - W1LBM

The Heathkit HW-16 was great for CW work, but it was no go on SSB.

Just started watching your videos and find them extremely helpful as I learn about restoring old receivers. When referring to "rf" while you were discussing when to use film versus OX/OY type resistors, are you also including the rf part of receivers too (just curious as your example was a transmitter).

It’s Been 5 months Mike . Looking forward to your next Video Mate new Subscriber from QLD Australia.

Great lesson thanks . 🙏

This is a great explanation. Just requested access to your Facebook group.

What kind of SDR and software do you use as your spec-an?

I need a variac in a hurry so I ordered one of these after watching - very helpful video. Earned my subscription, thank you sir

All good info, Mike. Pointing out details on the schematic helps a lot. I just bought a DX-60 to restore and your videos will be a great help.

It would've added a lot to have examined the schematic with us viewers and explained where the new parts went, especially the rewired power cord, and other changes you have made.

I just repair an philips 90 RL 152 , with only a meter and another pocket radio , the only thing i regret is have not the RF Gen , and ST , because it take me long to figure the problem . Thanke u sir for vid

New Subscriber Here. Would You show and describe what test equipment you use? I didn't know how off the alignment had been. Can you explain if you do a SINAD or not and the reason to do or not to do?

Thank you for the Demonstration. I just purchased a Heathkit IT-12 and also have the signal generator. I never used the IT-12 before and this video showed me exactly how to use it. I searched all over UA-cam for a tutorial and found none. I happened to see this pop up on tube radio repair so I clicked on it. Then I saw you at the work bench with the IT-12 and signal generator and hoped you would demonstrate them and YOU DID!! Thank you!! I subscribed and will catch up on all of your videos.

Thank you

What Size Bristol wrenches does the S-76 need to remove the kknobs ??

So did you inject the signal through a capacitor?

Thank you Mike. Good information.

Incredible how many Amps you guys need on 120V. I have this same model but for 240V and it's only 6.6 Amps for the same Wattage.

I'd like to watch. See one, do one.

l like how you explain the design issues as you come across them. The regulated vs. unregulated B+ and how that power resistor would affect both voltages and possibly the alignment is such an example. I've got an HQ-170 sitting in an upstairs bedroom I'd really like to get working again so this is of great interest to me. Thanks, Mike.

Some of those domino mica caps were actually paper caps, especially those made during WW2 when mica was scarce.

Off to a good start. Thanks for an informative video.

A great primer indeed. Thank so much for sharing your time tested knowledge. Much appreciated.

i have what appears to be a bad solder connection except i sucked off and reheated every single solder connection in the radio. I also cleaned all tube pins and sockets. Replaced all resistors and caps. yet i have an intermittent crackling and sensativity issue. The sensativity comes and goes. poking in the radio and wiggling does nothing. Moving tubes does nothing. But if i stand in the center of the room and lightly tap my foot it will crackle and reception will get better or worse. just like a bad solder joint. hitting chassis or tubes does nothing. only standing in room and hitting my foot on the floor or rolling my desk chair across the floor will cause the reception (connection issue) to either improve or get worse with a slight crackling. im at a loss what to do

I'm kinda wondering how the fuse can be in the wrong place when it, or at least mine didn't, have a polarized plug

Can you tell me the model number of this generator?

The very first thing that happens when a vintage rig hits my bench, the cord is cut so I don’t ever be tempted to plug it in. No restoration is started without the power supply section being 100% safe before moving on. That includes adding fuse or checking the fuse value and replacing any safety caps that are in the circuit.

Well planned and produced video. My first visit. I subscribed and will continue the series with great interest. I bought an S-76 today so should have mine on the bench pretty soon. Finishing up an NC-173 now. Thanks for the great content, tips, etc.

Thank you. Great video.

I am amazed at how those Parrot can Mimic the Ham signal,s and roger beeps, Just awesome.

Thanks!

Hi Mike. Mike here too! Awesome video series. Im in the process of restoring my S-38B. Ive made all the necessary safety modifications and recapped/re-resistored it. Powers up great and works! However, on the lower half of all 4 bands, the radio makes loud popping sounds. Upper halves work perfectly. I suspect that the tuning capacitor blades may be contacting eachother. Does this sound like a good guess or do you have any other tips?

I appreciate and enjoy your videos...my dog, though, not so much. Haha! She runs out of the room when the birds start warbling! 🙂

Hi Mike. I just acquired one of these for 35 bucks! It's in great shape too. I'm in the process of restoring it. Thanks for this series! Very helpful.

Well I learned that my hopes of restoring old radios is for the next life. Great detailed show!

It may help some to show where you inject the 455Hz.

my FM is not working, it was for a few minutes then it die on me, my radio is a loewe opta telefunken. what could be? the ECC85 is good for FM

Hey Mike this is Mike. Do you have or do you know where I can get a voltage chart for the SX-100?

mine is just like the one in picture!!!

Mike, do you know anyone in the Wisconsin area capable of repairing/aligning a Hammarlund HQ-125-X and a Hammarlund HQ-140-X? They both work, but they could possibly need some maintenance. Thank Mike. 73's de Bruce - KA9GVL

Thank you for this. I'm picking up an SX100 in a few days so I'm not sure what surprises are in store, but I hope to do a proper recap and a thorough check of all the resistors. One question, could you provide the spec of those safety caps you used? In the schematic I downloaded there's a 60uF and a couple of 20uF electrolytics listed.

I bought my Johnson Viking II from my Elmer back in the 70's and it was a work horse for my cw ops for a few years. I had the VFO as well and it never gave me a bit of trouble but I never did try it out on AM phone. 73, WA4JAT

Mike would you consider working on my GE Super Base? Thanks

This one is on Deck. So Glad you are doing a video on this transmitter. One of the few Johnson's I don't have yet in my collection. Great vid! I hope you do A Valiant at some point as well.

Please lose the anoying sounds.

I enjoyed the video Mike. On a different note, I replied to your pm message.

I've adopted this same method over the years. I too have seen and experienced failures over time when crimps by themselves try to live in the dirty wet environment of the world. 👍

Thanks! The information provided assures long lasting durable connections safe from the elements. It’s amazing how just a little extra care makes such a big difference.

Thank you Mike. Very good information. Kind regards.
