- No grid drive? Better take a look at your VFO. Many of these radios travel thru D-lab. Most all need this service. Yes, the VFO is the hardest area to service. However, if you do it right the first time, the radio will be good for many years to come. If you detect symptoms (EX: drift, smells hot, frequency jumps) , but do not act, the VFO can go up in flames. Then this repair gets very expensive. I have seen so many in bad condition. Take the time, Love your radio, then it will more than likely outlive you! I love working on these pieces. Hopefully I can keep it up, as many are in need of this TLC. Hope you enjoy this info. If you have questions or need my assistance, contact me! TD

When I worked for Radio Shack in the 90's while in College, they were still honoring...or..trying to honor the lifetime warranty on the Realistic tubes. If we could not get you a replacement tube, we would give you something of equal value. I don't think anyone ever came in the store while I was there to trade in a tube.
A beautifully restored Johnson Ranger. Great job Terry! My husband and I are impressed with your gentle care. Greetings from Nova Scotia.
Another excellent ham video. I know how much you like the Johnson line, have you ever seen the Viking "500" transmitter, it claimed to have an output of 500-600 watts. I found it the the 1963 Allied catalog for $1050.00, that's $8798.00 in 2020 dollars.
Wow .... that was super cool getting to see inside the VFO! Seemed like a pretty intense and extensive job. Thank you for loving what you do and for having the patience/know how to keep those old units running! Amazing work Terry!
Love the professional talking description and walk through of the whole repair procedure
In canada we are in self isolation and my entertainment is watching D lab videos
Wow, keep them coming
Thanks so much from Radar

Another great job Terry. You are the master. Transmissions? Not to bad, rebuilt a few in my life.
Great job Terry.
Fantastic Job Ter,, you are truly amazing,, thank you for posting this..
thanks for your shows were all on lockdown here in uk ,
4:05..."tweakadee doodah"-!! I'll have to remember that one!!!
Roll uuuuup! Roll up for the Mystery Board! The Magical Mystery Board is going to drive you insane, going to drive you insane, oh what a paiiiiin.
Radio Shack looked at me like I was crazy when I took back two lifetime warranty 6V6's and told me they don't honer them here in the Denver Colorado area
they were sending them to Japan I think.
Last I heard a(a few years back), if you pressed the issue, they would make some calls, and get you a replacement tube-the new one would say longlife instead of lifetime.
Of course, this is probably impossible now.
Radio Shack has been closed here east Pennsylvania for many years.
...youre lucky that you even HAVE a Radio Shack in your area- there are a HECK of a lot of us who aren't so lucky-!!!
You mean you actually have a Radio Shack store?? I thought they were all closed...🤔
Lacquer thinner Eh? Good tip.. we still have 2 Radio Shacks in Wisconsin.. I am amazed that these Johnsons still go for over $500. You sure are good with your Johnsons.
nice Terry
Hey Terry, great vid, as always! If possible, would you be able to set up an overhead view the next time you are showing us something like the cleaning of the vernier drive? I ask, because there were several times where your hand or the paper towel was getting in the way of the view of what you were doing. Thanks again!
Terry -- Be carefull, that is laquear thinner and not your wine.
Great Job
Thanks good job
I once pulled the face off of a PRC 77 xciever and spring tensioned gears flew everywhere.
That was fun.
Nothing in the tech manual about it or how to put humpty dumpty back together again. Jewelers tools and patiently playing....
Thx for the video, stay well.
You don't use acid brushes for cleaning? They were my favorite tools.
No debris left behind.
I worked on the PRC-77 in the Air Force. I also worked on the PRC -25 which is basically just the Tube version of the PRC-77. Also repaired many VRC-43 and VRC-46 mobile radios.

Nice
Damn. You Johnson fans are a tough crowd. No advice on a DX-60 in AM mode? No speaking to a Heathkit fan? I see how it is around here... I'll stick with my DX-60, and you boys just keep playin' with your Johnsons. I'm good. My DX-60 will sound better than your Viling IIs, Rangers, and the rest of 'em! This is my last comment post. Thanks for the vids Terry
Man, you had to take half of that radio apart just to get to that goober!
Is it too early for wine??
Again, the last *CLOWN* that worked on this unit didn't know what he was doing!!!! Sure left you with too much work!
Could you use vaccuum grease instead of the stuff you were using? I used it for years doing instrumentation mechanical assembly and the like and had no problems with it hardening or gunking up rotating assemblies and such. Just wondering.
Great video as always Terry. Did you hurt your thumb opening a bottle of wine?
Poked it on a sharp chassis area : ( OK now
I've completed my purchases on flee bay and am now ready for restoration. First off my Proud New Novice in '65 station featuring the star of the show: the amazing HW-16.. then with the addition of the novice's christmas present after he upgraded to General that year - a box of parts that said Heathkit DX-60A on the side - and the station becomes the 'Happy General in '65 station'. Now I'm afraid it was all for naught... wanting of course to work some quality AM with the old farts, goats and buzzards. Give it to me straight D(oc) Lab: will I get laughed offa the bands with a dx-60? Even if i do acceepted audio mods? Seriously. Will I? I think DX-100s are respected but mainly cuz they weigh more than the ham and besides I don't own one. I'm but a lowly QRPer you see..... 73 OM
Was I mistaken or were there a lotta nasty soldering connections... Musta been a kit... Then hacked... Poor Ranger!
I guess you don't have any 6136 tubes?
Would you normally get in touch with the owner and ask about those mods? Just curious...
Yes Sir, Did that, Past mods, no docs
Was the missing nut for that loose screw inside of the VFO?
Yes, I was amazed that it did not damage the unit
@@d-labelectronics, you lucked out there for sure.
2nd comment cuz I suck obviously. I think the grids are supposed to stay home until such a time that the freak-out is over because Trump is da man. Don't drive grids, stay home. Also - your videos are very very pleasant to watch. Informative? When the heck would any of us have a chance to even see this beautiful gear, let alone learn abuot it's features, weaknesses, etc., and get to see it repaired properly? Very cool work you do.. and very entertaining vids as well. Thank you - and be careful.. from your friends at the Northern Outpost (clio. lol)
5:00..."HASTE MAKES WASTE"(?)
VA6RDR what is wrong with me lol
Not VE lol
6:07 there is no evidence someone is inside before. En that's always my problem that some is inside before, whit no background of electronics but think repair something. And then just move all the evidence and tracks. And worse, they do more damage. If it was open before the nut and lock washer was gone = evidence. That is why I no longer repair devices that have been messing around with before. But we know the expression of some people here "12 crafts 13 accidents" .
thats the problem with real friends.... you want help them...day and night... ;-)
A whole video and I didn’t get to hear him say “fillder cap” 😢
