    That radio's case is immaculate. I like the factory applied "fingernail guards" around the knobs. Looks like long fingernails have been a problem for a long time now. I've seen microwave ovens as well as some oven range keypads (for setting the clock, etc) that have been damaged by persons using their nails to press them, actually breaking through the plastic membrane.
    Thanks as always for the informative and useful videos, Dave. Good job 👍

    You are the only person who I have ever seen using splicer scissors on chassis work. They are damn good scissors for electrical work. Used to have one but after three moves it got lost somehow. Good advice on wax paper caps. They were
    never designed to work over 15 years and maybe 8 years on the electrolytic ones from this era of tube radios. Yet there
    is an older gent from Canada as well who tests every old cap like it is precious and leaves some in if they test good on his
    old Heathkit cap checker. He uses WD-40 on everything he "repairs". Yes I stopped watching him and his crazy way of doing things. You did another good job again Dave.

      Those are Klein electricians scissors. I have a pair at work too and a Miller. Had the Klein's at work for the past 17 years. Got them when i did a stint in cable splicing. Now all that work i did 17 years ago is being retired as fibre optic is the norm now. The new ones they give the guys at work are Chinese and they rust pretty quick.

      Yeah I've got a few. Most of mine are small table radios. I'm running out of places to put them I guess I'll have to make a trip down to Ikea and pick up some of those lack shelving units so that I can put them up on the wall on display. I collect them but I don't necessarily listen to them because I don't want to run up unnecessary hours on obsolete tubes that can burn out. So I restore them so that I can turn them on to test them but I don't use them.

    • @12voltvids

      It's the voltage. Many of those caps from scrapped boards have relatively low voltage. Tube gear requires very high voltage rated caps.

      The thing with the old caps from the 70s was back then many of them used in oil based electrolytic and some would have contained PCB oil back then. In the 90s capacitors changed from oil-based caps to fish oil based and then to water-based solutions. Of course the water-based capacitors don't have the environmental risk factors that the oil-based ones did when the product reached the end of its life. The problem with oil based especially PCB laden capacitors was what happens to them when they're disposed. If they go to landfill those chemicals will leach into the ground, if they're incinerated they go into the air. So they had to get the hazardous chemicals out of them. The thing is the new ones don't have the same sound. ESR is different and changes to the internal resistance will change the way the capacitor couples the sound. I thought the new one sounded fine myself but this chap didn't like the sound and he paid me over $100 to take out the new ones that I just put in and put the old ones back in. This was a long time ago about 10 years ago. This was just before I started filming these videos. The first one that I did was a power supply rebuild for an old satellite box and it looks pretty bad if you were to watch it today it wasn't shot with the intent of putting it on TH-cam it was more just to show the owner what was wrong because he wanted to see it. That's really why I started filming my work to begin with was because I had a fellow who I'm sure has been dead for years now because he was old at the time who wanted me to fix his satellite box at his house and I told him I didn't have any test equipment or tools and he was quite upset because he wanted to see what was inside the unit see how I diagnosed the fault. I offered to put the video up on TH-cam so he could see it being repaired. The initial video was never intended for everyone just a few ham friends. Next thing i know TH-cam is emailing me telling me the video has 100k views and they have been monetizing it and holding money for me and they invited me to become a paid partner to produce videos. I wish i had filmed the cap change and putting the old ones back. First so i could compare the sound on camera but also to show the naysayers that the new caps didn't necessarily improve the sound but did make it sound different. To my ear and this is quite foggy now but the newer caps sounded much brighter almost two bright. like I would be reaching for the treble control and turning it down. Many people may like that brighter sound but to the guy that owned it, who was a perfectionist by the way he just could not handle that. To him it sounded like crap any part of with another hundred bucks to get it put back the way it was before. But it certainly opened my eyes that just because changing every cap sounds like a good idea may not necessarily be the best solution. Unless you want to sell it and figure you can get top dollar by claiming it's been totally recapped because some fool will pay more for it. I say leave well enough alone if you're happy with the sound don't touch it. That's a game for more modern equipment. When you're dealing with old vacuum tube gear that has these old paper style blocking capacitors they have to be replaced because not doing so is playing Russian roulette with components that are no longer available. So when something like this it's not for sound improvements it's to prevent catastrophic failure of expensive parts like transformers and tubes.

    I know who you are talking about when it comes to the outside foil and who the other person is. I agree with you and I never check I just put them in and have never had a problem with hum so therefore I dont worry about it.

    • @12voltvids
      @12voltvids  2 ปีที่แล้ว +1

      Well that's just it it was an issue back in the days of the paper capacitors which were physically larger but with these new ones the small ones when I check it on the scope there's virtually no difference you have to look closely to see the slight difference in the amplitude there are so many factors like if your hand is near the capacitor when you're testing it you could skew your readings. Think of it this way if it was an issue the manufacturers would still mark the caps for which lead was connected to the outside foil. They always mark them in the past because it was an issue due to the physical size of the cap and the amount of foil that was exposed. But only small ones forget it you're never going to hear it and that's why the manufacturers don't bother to print it. Like I said I used to go through the bags of caps and check them all and usually they were the same usually it's the one on the left side with the label facing you not always some brands was the opposite but generally I found if I bought a bag of parts all the ones in that batch for the same. But it's not a big deal not these days because the differences are relatively small from one to the other so I don't worry about it anymore. I know I'm going to strike a nerve to a certain purist probably going over the deep end right now but you know some people are going to be concerned about that if you're going to lose sleep over the outside foil on a cap they're a bigger things to worry about these days than that. 9 out of 10 people that are fixing an old radio like this are not fixing it to listen to. they're fixing it so that it is operational so they can plug it in for their friends and show them that it works but not to sit in front of the radio and listen to broadcast from around the world not that there is much on the shortwave bands these days and for that matter there's not that much on the am band they're more of a novelty for people these days. It's like the dozen or so radios that I have I don't sit and listen to them in fact nine times out of 10 if I'm listening to the radio I'm not even listing to it off air if I'm at home I'm listening to it streaming through one of my streaming devices. I'm doing that right now listening to a local FM stations stream because their signal is not that strong it sounds a hell of a lot better on their digital stream than trying to pull them out through all the noise on the FM band because they're signal is pretty weak

Or so it seemed. When she got a new set i was just getting into TV repair so I took it and tinkered with it in the garage.

      The best iron I ever owned was the Weller ec2000. I used that for years in the shop that I worked at I supplied my own because the shop wouldn't supply a fancy one like that and I paid a lot of money for it over $400 when I bought it which was a shitload of money back in the early 1980s. I use that iron for years I remember how pissed off I was when I came in one Monday morning to find the cord between the base and the iron had been cut over the weekend when the shop owner was babysitting his two sons that were like three and five or whatever their ages were at the time and one of them was playing with wire cutters at my bench and cut the cord blowing up the control board. The boss bought me one of the magnastat Irish to replace it and I said nope not good enough you're buying me $100 iron to replace one that I paid $400 for I want it fixed. The boss sent it out it cost them almost as much as I paid for it to get a new iron and get the power board repaired. I use that right up until the last days the shop when I quit I took it with me because after all it was mine and it sat on my workbench basically where it is now until the temperature sensor failed. I went down to main electronics to try to get a new one and they told me that the parts were not available and that was the end of that iron I still have the base for it but I couldn't get a replacement element. At least I couldn't get it at the shop that I bought all my parts at and believe them when they said it was not available and bought a cheap one now this would have been probably early 2000s and I really wasn't doing much work so I didn't want to invest a bunch of money as in hundreds of dollars just try to track down a replacement iron which is what it would have cost. even recently I tried to get a new replacement handle but wasn't having much luck one of the local suppliers gave me a few dead handles from a few other irons but the first one I tried didn't work. Heater was shot. I have a few more to see if i can rewire the base and make it work.
      Got out of the blue one of my viewers contacted me and said he had one that he picked up at a recycling center I think he said and will send it to me. Here we are nice Weller ec2000 again. went and bought a few new tips so I have the different sizes and styles of tip and I'm enjoying it because it's what I used for 20 years in the business and it's still what I consider to be one of the best soldering irons ever made. Anyone who has ever used one I think will agree. I recently had someone comment about how thick the handle was and ask if the grip can be removed. No it can't at least I've never tried to remove it because I kind of like the handle the way it is nice and cool to the touch and big enough that you can hang on to the thing. I find the skinny soldering pencils just are too flimsy.

There has been a few at work that have done that and the end result was the same. Of course the correct procedure would be to call dispatch and inform them that the OT job that was booked was a no-go and find out if there's any other work that can be done on that OT shift. If the board is clean you request to end your OT shift and leave, that also usually involves a call to the manager to let them know that there's no work and that you're ending your OT shift. going back to the yard and watching TV for 3 hours is not the correct answer as a few of my former co-workers have discovered! of course every time this happens the rest of us get an online course to remind us what the proper procedure is.
