Oh wow! Just yesterday I was cleaning out my dead subscriptions, but decided the chance of a new DR H video would be worth hanging on! Love your videos bro, welcome back!
Thanks, Doug, I'd never known about the existance of this technology, and it's not referenced in any of the Mil Spec Soldering class instruction references, from the '80s or '90s; this further explains the "Kester Specialty Catalogs" of the day; they'd bailed our tails out a time or two! The 63/37 percentage gets you close to the eutectic properties of Sn63-Pb37, and the inclusion of the Ag into the mix, being 'already bound' to the tin and lead, introduces the adhesion necessary. This explains some of the "voids" in the art of mechanical VHF tuner design and repair, and adds yet another reason for sending tuners to PTS for repair, back in the day. Great to see that you've presented us with another "gem", many thanks, for sharing your knowledge, and discoveries, which help in our understanding of technology's progression through time. I've learned so much from your video, and written offerings, again, Doug, many thanks!
Finally another video of yours. I like your videos so much. It is a pity that you don't make videos more often. Me and others I am sure that would like to watch more videos of yours. Specially those videos of vintage equipment and electronics. Best regards and thank you for making this video and I hope you upload much more and more often. Sorry about my poor english.
Back about 1986, I remember purchasing a old Tek scope with these exact same connection points, and one had a high voltage arcing issue between 2 connections. Luckily, I was able to clean that spot into submission, and small coils of silver solder were readily available at Radio Shack. The scope is long gone, ( It was heavy as all he**, lol) but the memory of these connections still remain.
Hope you are well drh4683 and thank you for all your efforts and wonderful videos! Please let us know how you are doing. Looking forward to more of your great works and hope to hear from you soon!
Welcome back Doug. I always appreciated your videos. Informative, interesting and entertaining. I'll be on the lookout for new episodes in the near future :)
Many if not all of the Tek products that used these ceramic strips usually had a small roll of the proper solder placed inside the chassis somewhere. But on most vintage gear that was probably long lost or stripped out. Good info on the temp. I knew about the silver bearing solder issue but not the ideal temp to use.
The big cart-mounted 500-series scopes had that roll of solder inside. I had an early '60s 561A benchtop scope, there was no room inside to mount the solder spool.
Found this a week too late, I can only hope the equipment I was repairing will survive that one-time fix with the 60/40 solder - I think I'll start looking for new strips just in case...
Always look forward to your videos Doug; they are most interesting. Have I imagined it, or did you do a video about your house at some point? I've just been watching your Ray Conniff Christmas music videos which feature your 1960s living room and it sort of reminded me that I thought I'd seen another of your videos, in which you showed the living area of your house with some history about the place etc?
Glad to see you back making videos! Love your Zenith Videos! Do you happen to have a Zenith Chromacolor B4030W in your collection you could make a video on? Had one when I was a kid and miss it greatly!
Can you use commonly available silver lead free solder required for potable water plumbing copper piping? This solder normally has no flux. You would have to use liquid rosin flux.
That *might* work, but I try to keep it close to the original content as much as possible. Keep in mind that the melting point of 62/36/02 (tin/lead/silver) solder is much lower than the silver lead free solder, so you'd probably end up having too high of a temperature to melt the lead free which would ultimately damage the silver on the ceramic strip.
How you doing my friend do you think maybe you could make some videos on your classic cars again it's been several years I sure like to see how they're doing you still got the black Impala 60? Or how about the 71 Dodge Coronet Brougham? Do you still have the 65 Chrysler I'm not sure? But I'd sure like to see how everything's going with you and your cars I know you're more into the TV's repair but still that's a part of your life and I'd like to see it?

I love your videos. Please, I hope you will post more!
Love your videos. Keep them coming
Thanks Doug, great service tips! Hope to see more from you in 2019, miss your logical troubleshooting and circuit analysis videos.
Nice video my freind god bless you

You have a fantastic channel!
Were you been? Miss you're content repair video's
Tektronix always made great test gear. They were built solid. I have a Tek 465 and 2465B that's still going strong!
Welcome back Doug. I always appreciated your videos. Informative, interesting and entertaining. I'll be on the lookout for new episodes in the near future :)
Excellent information, Doug. I sure hope you will share some of those amazing estate sale tv finds, too!
Good to see you back Sir
It's time to come back. I want more repair tips. I need all I can get.

Wish you made more videos.

excellent
i miss your vids i hope you are doing well
I wonder what the advantages of that style of terminal strip was?
Glad to see you back making videos! Love your Zenith Videos! Do you happen to have a Zenith Chromacolor B4030W in your collection you could make a video on? Had one when I was a kid and miss it greatly!
you should give more of a tour of your home the rooms and bathrooms etc
Hello??????....you still there? more videos please?

Come back!
Hi drh4683, how can I make contact with you in regards to vintage TV repairs?
Vince
Doug no - Today lead free solder very bad,, most boards use lead free solder not good, lead solder skiver works the best, shop Jimmy
waffling lol
