And at this point now I think your overreacting , the Man made his comment , you responded to it , it's now time to do like Elsa and "Let it go" ....

That is , unless of course your looking for an internet dustup , in which case by all means continue . Just remember the guy Levi ("CaptainClock") who posted very suspiciously like you do got banned here for the very same thing , not knowing when to walk away from what is really a pretty minor issue in the grand scheme of life

I'm not trying to start anything or keep anything going, I just find it frustrating that the OP of this thread decided that he would make it his life's goal to try and convince people on here (on my thread of all places) that dim-bulb testers are somehow bad for the environment.

Which if he wanted to do that, should of just started his own thread elsewhere in the forum to discuss that topic rather than spamming my thread with his topic.

And on that note I'm going to stop while I'm still ahead.

Cool , may the vacuum tube Gods bless us all and may our bulbs be dim and our CRTs bright

Gentlemen,

My name is Scott. I grew up in the '60s and '70s, got my electronics degree and have been working on modern 3 phase UPS systems for more than 30 years. About 10 years ago I built an Internet radio and picked up a TeleTone AA5 to house it. I looked at the removed chassis and figured out what was wrong with it and that started my fascination with tube electronics. I've restored several radios and TVs since then acquiring (and restoring) vintage test equipment along the way.

I am not trying to keep this going but it was never my intention to slam anyone other than the "Stupid Law" comment. I attempted to respond to the portion of vortalexfan's thread after Electronic M made the comment but I did not realize that my comment would be added to the end of the thread. That made it appear out of context which I now understand.

I obvious agree that the 2007 EISA decision restricting 60 watt and lower incandescent lamp production based on efficiency is a good thing. It does not mean you can't find these lower wattage lamps. It simply means that your typical source for these bulbs will likely dry up because marketing LED replacements are becoming more popular. The reason I commented in the first place is I was following vortalexfan's troubleshooting of his Meck TV and wanted to encourage a more sophisticated approach. I have re-read the thread and I now realize that not only was he struggling on some of the most basic troubleshooting concepts but his financial situation could not support my suggestion. I apologize for misreading the thread and writing a comment that was easily misunderstood.

I have benefited from being a videokarma member for more than two years and I'm hoping to regain trust from the membership.

With respect, Scott

Speaking for myself only , because it's not my place to speak for the rest of the membership ;

I don't believe you've lost any trust here , you sure haven't lost any with me ! People have small disagreements on internet chat forums all the time , it happens , and we are actually truly blessed that the disagreements here don't rise to the level I see on the model airplane forum I belong to (Pick just about any thread at the RC Universe "AMA discussions" subforum to see just how ugly internet dustups/trolling can become) . An off topic side comment was made , you posted your view about it , and that in itself is no reason for people to distrust you . Now if you had come in with figurative guns blazing tossing verbal bombs everywhere sure I could see folks taking issue with that , but I'd hope we as a group DO have the mutual respect to accept that there WILL be disagreements on various off topics and not go holding lifelong grudges over such small issues .....

Oh, wow! I haven't been an AMA member since I got my pilot's license in 1999. I can only imagine how that would be. As Roseanne Roseannadanna used to say, "It's always something!"

Thanks for the kind comments.

I stocked up on incandescent bulbs when I learned about the ban, and now I have a closet shelf full of them. But I bought LEDs anyway, to save on utility costs, and my stock is unlikely to ever be fully used. Incandescent bulbs do certain things their replacements cannot do, but I probably only have two or three left which I use semi regularly.

I switched because a better product appeared, not because the old one got banned. I believe the same thing could have been accomplished though tariffs and subsidies instead of an outright ban, which had the side effect of making non energy intensive specialty uses of incandescent bulbs harder to accomplish due to lack of supply.

That said, I suggest a variac plugged into a kill a watt instead of a dim bulb. I think dim bulb testers are more use for amateurs troubleshooting audio equipment - I have never seen a pro tech use one.

Do You still fly ? I got my FAA A&P mechanic's license back in the early 1980s (now blissfully retired) and although I never did get a Pilot's license I have considerable stick time doing "check rides" of repaired aircraft . The RC models are a great way to keep the old brains sharp , although my aging eyesight will eventually end that , it sucks getting (gotten ?) old . An interesting side topic , do you know that the FAA is now requiring RC model pilots to get a pilot's license ? Due to the huge expansion in the drone hobby the FAA decided that all pilots of "UAS" (Unmanned Aerial Systems) have to be registered , with a knowledge & skills test to be rolled out sometime in 2020 . Kinda weird times for sure when pilots of what the general public sees as "toy airplanes" need a pilot's license ($25K fine for getting caught flying anything over 2 pounds without one) but with the risk of a drone , operating beyond it's operator's direct line of sight , taking out a full scale aircraft , the FAA was forced to do something .

God bless Gilda Radner , it IS always something

I do still fly. In fact, my BFR is scheduled for tomorrow if the weather holds. It's always tricky this time of year. I used to fly RC for years before jumping full scale. I was active in a Pontiac, MI club for about a decade. You know the drill: build in the winter and fly in the summer. I still have a giant scale and three of four park flyers but I am sure to be really rusty. It is amazing the progress in LiPo technology since I was active.

I was into building drones before the corporate world took over. It was fun being part of the hardware and software development but my two home built drones are way behind the times. I do have one of my drones registered with the FAA but I did not hear about the pilot licensing requirement. I know there is a regulation and airspace operating requirement for drone pilots operating in controlled airspace outside a AMA sanctioned field and that's something I support but it does surprise me if that extends to a local flying field. I have a good friend that makes a living as a drone photographer but I've never heard him talk about having to have a pilot's license. At least not in the traditional sense. You've peaked my interest. Now I must investigate.

Hi Guys,

I've been struggling on how to fix a horizontal width issue (way two wide) and I stumbled upon a solution but it worries me. I was testing C106 and forgot to re-solder it and all of a sudden, I have good width control via T4. I've not replaced C106 for leakage (I can test up to 450V) but I've substituted an equivalent arrangement of multiple capacitors and with the new arrangement, the problem returns. I've not replaced C106, R106 or C107 but I'm not sure they are the problem. With C106 left in place, the best width I can achieve is about 10-15% overshoot with the T4 slug fully retracted. With C106 out of circuit, I can adjust T4 to a midpoint and achieve a normal width picture.

I've looked through Grob's, Basic Television Principles & Servicing but nothing quite matches the example designs and this RCA. Has anyone run into this issue? How about the purpose of C106? It looks like some kind of boost bypass to one side of the yoke but I'm not sure why. Second question, can you think of any long range issues keeping C106 disconnected?

Thanks in advance, Scott

Yes , right now the FAA is finalizing the requirements for recreational UAS users , you friend being a professional drone photographer is already bound by a more stringent rule set known as Part 107 . Part 107 requires a pre filed flight plan for all commercially operated UAS flights , already has a knowledge and skills test if I recall correctly , as well as a remote identification requirement to be enacted sometime in 2020 . Like you said and I can't blame them one bit , the FAA had to take action before a drone takes out a full scale aircraft , but my own opinion is that RC aircraft being operated within their operator's direct line of sight are not now nor have ever been the same collision risk as an RC aircraft being operated by an operator using remote cameras to conduct the flight . "See and avoid" has worked well for traditional line of sight RC model flying for many years , it was the advent of the remote cameras where the operator no longer actually sees his RC aircraft and what's near it that got the FAA's notice .

Back in the 1960s, they sold a device that went between the damper tube base and its socket, placing a capacitor between the plate and the cathode of the damper tube. The device was used in cases when you didn't have enough width. They came in two values, standard and extra width gain. I suspect C106 is doing something similar. One thing I would check is the value of the 650 V boost line both with C106 in and out of the circuit. If it is close to 650 V with C106 removed, you should be OK to leave C106 disconnected.

No harm leaving it out if that gives you the width range you're looking for.

[Notimetolooz]

I think that C106 may form a resonance with the flyback winding. That could make sense that it would effect the width. May effect the boost voltage and HV also. Is there a chance that the flyback was replaced? Did you confirm the original value of the cap? SAMS has been know to make mistakes.
