- Yes, another Zenith console in need of attention. Not in line with my current priorities, but I needed some fun time. This one has the 5808 chassis. A very popular radio. Cabinet is in super condition. The radio itself, not so great, however repairable. I was almost ready to give up, since it had so many issues, then it spoke to me, I was sold at that point, time to restore this beauty. This is part 1. Part 2 will wrap up the repair. Not sure when I can get back to it. I have been swamped and need to address incoming repair jobs. Will do my best my friends. Thanks to all for being part of the D-lab journey. TD

This radio is very much worthy of great attention and care! It DESERVES new wiring, new capacitors, new belts, etc.!!! A thorough cleaning of the chassis, and all other parts, with tons of TLC as you go about it.
Fantastic fix for that switch by the way! Good on you!
I had one of these when I was just starting out in electronics as a young teenager. It was already 20 years old, I'd lugged it home from the attic of the last farmhouse on the road in Long Island before they converted the farm into a housing development. It needed some cleaning and eventually some new caps, but it worked and was extremely sensitive, especially at night. Listened to a lot of DX on that old thing back then.
Eagerly awaiting *Part 3* where you kick back to sip some good wine while listening to that old Zenith (not) humming away... 👍😎👍
Great job, looking forward to part 2
Definitely looking forward to part 2. I love old radios.
Great save Terry!!
Love the old radio stuff Terry, keep at it Fella, part 2 will be great i am sure. Thanks for sharing...Vic KE8JWE
Brilliant fix for the broken linkage! Necessity really is the mother of invention. I have learned a lot watching your methodical and logical way of moving through radios to bring them back to life. Thank you for sharing!
Wow, I love these green eye’d radios. Thanks a lot for sharing. Can’t wait for part 2. Take Care :-)
Thank You Terry. I am truly looking forward to part 2 Great fix on the switch.
That was awesome so far Terry.😁 These elderly radios just need some love!🥰 Loving that band switch repair, great idea. Will be anxiously awaiting part 2! Someday....
cool vid. still enjoying my dlabs 9s367 chassis all restored.
Terry, I have 2 or 3 of those Band control linkage's, I will send you 1 if you want it.
Please help Terry out if you can,send linkage and a rubber belt/o-ring.
That was EXCELLENT. It would have been cool that when you got audio, it would have been programs from the '40s. 😊
Handsome rig, Terry! Nice that you are bringing it back to life.
Nice practical repair on that lever!
Thank you Sir
@@d-labelectronics Could it have been silver soldered with the bushing removed?
Hey Terry, kudos on that band switch lever fix! Nicely done.
Thanks for great video and for saving an old classic . Love old 30-40s tube radios. You do a very good job explaining testing and repairs. Keep the great videos coming.
Excellent field expedient on the tuner arm
I am amazed with the old Zenith radios. They will live if given a chance. Loved this video, love your work.
Love the old radio and old boy toys.
I loved the repair! I am attempting to replace wires, switches, capacitors and tubes
on an 1941 Wards Airline 80 watt AM and citizen band model 04WG-1168 radio!
You rock Terry.
The JB Weld was genius! Had same problem with my 1066. Worked like a charm! Thanks Terry!
Where is part 2?? Ok, I said it. Lol. Cool idea re-fab'ing that lever
Nice work. Glad you showed the point where you were about to call it as a lost cause, we all reach that point, but you showed how old gear can surprise you. I especially liked the band select fix, similar to what I was thinking could be done but your method with the J-B Weld probably worked out simpler. If it's rugged enough and hidden from view, great!
As for Part 2, we'll see it when you do it! ☺
Now you made me (thanks), have to take a look at my Zenith console Farm Radio 6J357 which just recently stopped playing. Picked it up around the block at a garage sale and to make it play initially it only needed a replacement audio transformer. Listened to Radio Australia from here in California to test it just after that component replacement....what fun. Also got replacement speaker fabric from Nico in Italy and visited him and his wife with my wife on vacation a couple summers ago and toasted with some local Prosecco.
Great repair on the switch Terry! Very creative use of washers. Lack of electrical engineer lubricant was troubling though.
Ah, you mean the wine, It was present, but not featured
That is well worth saving. I have a '46 Zenith console with both FM bands and it sounds great. Yours has the infamous 6X5 rectifier which is known to short and take out the power transformer. Best to replace it with a modern day one.
Terry- Why do you not make a speaker to chassis jumper? It is easy to do, & cheap too.
Use the base off of a bad tube for the male half and a salvaged tube socket for the female half. A few feet of wire & VIOLA!. I have quite a number of these home made jumpers I have made over the years. Also many times they will work on more than one make and model of radio. Good kludge repair on the lever assy! I have 1 left in my parts box when I get to restoring another Zenith I have.
It's alive! Bring her back .
nice repair
Greetings:
The tuning eye tube is definitely tired, but an increase in plate voltage can usually help. Currently the plate is connected to the output side f the field coil. Moving to the input side (from + side of c24 to + side of C23) )should increase the brightness somewhat.
Why would anyone down vote a D-Lab video??
First.thx terry utube keeps deleting my comments. Thanking u for ur video as a distraction from my situation of my 25k equipment and guitars liberated from my home. Guess I used keywords they didn't like with other things going in in the world right now.
Cool radio that needs that DLAB touch !!!
The 3rd band is the push buttons
I just finished restoring one of these, my family heard Japan bombed pearl harbor on the set. It was the very set that inspired me to go into electronics when I found it in my grandparents closet in 1968. I inherited it in 2005 and after being dark since 1947, it works and talks again. After many challenges everything is back except I now need the correct power transformer for it. Back in the early 60's a local shop put a 10S transformer in it and is way way too high of B+, that and the 6.3 volt isn't right either....but that'll be soon corrected.
I changed out the 6X5 retifier, Put a 5Y3 in with a Hammond 270 DX power transformer. Radio works great and no worry of the rectifier tube taking out the power transformer!. I also insatalled a line fuse for added protection.
I have the same exact set I was given yesterday the person got tired of it taking space.. it had the same switch issue which someone fixed. they used a L shaped piece of metal with a hole in it and they used a small hose clamp over the pot metal shaft and a nut and bolt to connect the two..
Issue with IF can could be the infamous silver mica disease tho I'm not sure any of the silver mica caps formed by layers of mica between two plates actually go to ground.
your dial belt lengths are
9-3/8 JFD part # 80.
and
9-25/64 length GC part # 115.
If you can find these two belts there is the part numbers.
these are the two listed for The zeinith 8S463 model from the "Radio Dial Belts" Book By Ray Bintliff. De VE3TYA
This was great Terry.
What will you use to fix the band adjustment?
I would have loved to have seen exactly how to replace those caps and with what.
This radio has cased Terry to consume probably two or three extra bottles of wine on this one. Lol
I love me some Zenith Radio's, but sometimes it seems like they practiced black magic. Mine had among other things a bad output transformer & speaker, a frozen volume control, several burned beyond recognition resistors and the usual bad wax caps....and pwr. transformer. Good luck.
Maybe not economical for shop repair, but if the power transformer is good, always worth breathing life into the dinosaurs. Old rubber wiring in the old ZNths a given.
Terry, I dont know about this one. Nice repair though
I did a 12S569Z with the rubber wiring replacement, bad tubes, and cabinet restore. It was a big job and unfortunately my oscillator coil ended up bad. Let me know if you happen to know of one available.
Also play the radio for a while once you get it recapped with the weak tubes. They are like a CRT where they become lazy from sitting around a long time and to wake them up the only thing they need is some use. I've seen it happen. Obviously shorts and gas or any other defects such as that get them out of there! Anyway if the set is performing well even with the tubes that are in it why change them? The best test of a tube is in the circuit.
I think I have that linkage you need. I have a pretty crusty Zenith that could be fixed. But, it needs completely re-wired and I don’t have the cabinet for it. So, it’s pretty much a parts chassis unfortunately. I have a deal in mind.
Deal? Love that word, e-mail me, contact info is on d-labelectronics.com
Just finished the vid. I guess you don’t need that linkage anymore. Ha!
I have a 1960 Zenith console and the FM frequency is no longer working. There is him but no reception. It did work but a little quarkie. There is a Stereo light that didn’t light up until I had the unit on FM frequency for about 20 minutes. The AM works fine. Would I need an antenna? Or is it another issue?
Do you think a 3D printed replacement part could work for the band selector?
Have you heard of a r119 steward Warner radio that is what i am trying to restore.Would like some tips have many faults with it.Getting 1 radio station out of it but it is squeaky between stations.
You mentioned a choke. What is that?
Where there is a string for the tuning wheel, where else does it hook too, please give me some information where it goes, it's the same one you are working on, please and thank you
Repair that *PUP* !
Oh I see now there is a shaft within a shaft one goes to the volume control and the other one has a flywheel that's probably the tuner of course
If JB Weld fails, get some BONDIC UV activated adhesive, they use it to fill teeth, very strong,. Look it up on YT
Great suggestion. I was thinking of the same thing. The only thing is that you have to do multiple layers to build up the joint. And it's expensive compared to JB weld
What was the short? Was it in the IF can?
Where are you located? I have a one I would love to get restored!
Yup... If JB weld can't fix it it's really broken. I love old radios but where do you find people that will pay to have them fixed?????? Give them my number. Lol
If it's pot metal, it can be welded with CO2 as your gas. Bazillions of youtube videos on it.
There are reproduction bands witch links available.
I’d love to know who’s making a repro of that band switch arm?
jb weld will fix that bar!
I've got and 8S463 in my basement workshop right now! Very minimal cosmetic work needed. Power transformer is shot though, so I'm working on sourcing one. Any suggestions? I ask b/c the schematics don't give the winding voltages :(
As always, love your vids!
Oh, and for the band selector link arm, you could try this stuff: www.muggyweld.com/product/super-alloy-1/
I've used it in the past to restore pot metal toys (fill cracks and pits) from the 30s and 40s as well as fix a pot metal bose satellite speaker wall mount bracket.
What year is this radio i would say about 1935,34.
They should have used more knobs
Why don't you do live repair?
Day Job, eats up my time
Are those push buttons?
yes on the left for the tone and on the right for preselect stations .
terry, can I ask what your ham # are? I have a friend who may contact you on the air? Thnks!!

@@d-labelectronics thanks buddy from NW Montana!
I would have sworn I saw somebody making a reproduction of that band switch device. I wish I could remember where I saw it at.
I saw them too, but not offered anymore : ( Its OK, this method worked fine
No doubt in my mind the it would not work. "Made in the USA".
What! After just 12 mins you’re ready to totally give up?? Weak.
