Interesting video Vlad. As an electrical and electronics engineer i was watching with interest. Your work was fine. I would have changed both of the capacitors whilst the unit was stripped down, that is if they were the same size. It looks like something is shorting with the azimuth axis. Good luck 👍
Thanks! Yeah I'm not sure but the electrical engineer people recommend only replacing the c2 capacitor. Again not sure why but I have done that for years with no issue.
@@AVTAstro I suppose if it’s that individual capacitor that is repeatedly failing then it would be pointless to change both. Good luck with the secondary fault 👍
Likely so. Again I'm not the expert in the field and as far as the way that board actually works I'm about as well informed as how a cruise ship works... LOL.
@@AVTAstro I am an EE too. Running a 10 tantalum cap at 18V is a bad idea. In fact, most EEs will use use a higher voltage rating for Electrolytic (the vertical cylinders) and tantalums (yellow/blue vertical ones). Exploding capacitors are highly undesirable (unless you are doing it for fun). This can also happen when you install them backwards. I have launched the can of an Electrolytic across the room before by over-voltaging it (in my younger years).
Good video. While replacing the capacitors is a good idea, replacing them with tantalum caps again is not. All else being equal, electrolytic capacitors are a safer option, and less expensive.
sometimes I think the You-tube algorithm can read my mind. While at no point have I typed in anything telescope related in over 3 years. Just the other day I was thinking about my LX-50 10 Inch I own. I bought it new back in '96. While I know the 50 vs 200 are different animals it might be a good idea to check on the old girl before I try and power her up again just to be safe. THANKS!
Wymiana kondensatora nie raz jest konieczna w wielu urządzeniach elektronicznych. Często się zdarza że kondensatory ulegają uszkodzeniu, lub że kondensator jest nieodpowiednio "dopasowany". Dzięki za informacje. Znajomy ma podobny model teleskopu. Wiedza może się przydać😉👍🏻. Jak zwykle pozdrawiam serdecznie "astro-przyjaciół" po drugiej stronie globu 😄🤚.
By some insane cosmic luck someone in my local astronomy club gifted me a 10" LX200 that they purchased back in 1999. I haven't powered it on yet, but I just inspected the hand controller and it does look like the previous owner did have it professionally serviced at one point. A diode was soldered in parallel with C3 and flux on the backside of the PCB indicates C2 was replaced. Does this sound right to you? Should I have any reservations about powering it on?
Here is a link to info on what caps you need: www.cloudynights.com/topic/717518-meade-classic-lx200-hand-controller-3-capacitors/ Good luck on the repair!
Mine has twice now blown the board in the base. Always goes in a cloud of smoke and sparks. De forking now as to expensive to repair. Had it repaired once cost a fortune. Now its gone again sadly. Too expensive. De forking this time.
Since de forking my lx 200 I’ve been trying to repair the old lx 200 mount. Took the mount to bits today and found it was c8 burn out. Ive now replaced the burned out one with a new capacitor and it’s back to life. Going to replace the hand set capacitors next . Thanks for the help.
Bahahahahahahahahahah, they sure are not. This is a shirt I got when I worked at Fry's well over 10 years ago... Not to say that they where a bad cable. I still use some of them ones I bought back in the day with a heavy discount.
I guess I kind of don't think of the fact that some people might think your indorsing a brand by wearing a t-shirt with a brand on it while making a youtube video. I can assure you(and actually legally I would need to disclose it) that if I'm wearing some Nike gear(ext...) its not because they are sending me truck fulls of cash. No one cares about someone on youtube that does not have like 1,000,000+ subscribers. And in my book that's a good thing!
Great Modification Vlad!
Thanks!

Good tip, thanks!
My astronomy club has a couple of guys who maintain their two Meade scopes, a 16" and a 12" they have for outreach and searching for NEOs.
Very cool to hear they keep them running. 👍

Sounds like you should be fine. If you need a replacment controller I have some spares.
@@AVTAstro I powered it on last night and so far, so good. Thanks for the offer!
I know this is late to the party but does anyone have the replacement part number(s) and a link to the easiest place to order them from???

Good luck on the repair!
Did you figure out the R/A motor issue? I have the same thing going on.
Hi, no I did not. There is a lot of info about this issue on Cloudynights.
Does this issue concerne the more modern scopes? The ones that are 12 Volt. Are they also sensitive to voltage variations?
Hi, no the newer "GPS" models do not have this issue.
@@AVTAstro cool. Thanks
That sound! Omg it’s a noise machine.
If you're talking about me talking, I'll take that as a huge compliment;) Very helpful feedback!!! Need more of this... LOL.
Haha. Good one. Sorry, but I mean the mount. It seems to be a really noisy.
Lol, yeah the Meade mounts on the LX-200 are pretty loud. It's not a very present sount too at night.
Move existing capacitors to safer place.
Would not be a bad idea but newer capacitors don't explode like te originals from what I understand.
Mine has twice now blown the board in the base. Always goes in a cloud of smoke and sparks. De forking now as to expensive to repair. Had it repaired once cost a fortune. Now its gone again sadly. Too expensive. De forking this time.
Some times it's just the reasonable thing to do👍

Meade...lol...Should have replaced capacitors for clients..
Not sure if this was an issue when any of these where still under warranty.
Vlad… monster cables are not worth the $!!!!
Bahahahahahahahahahah, they sure are not. This is a shirt I got when I worked at Fry's well over 10 years ago... Not to say that they where a bad cable. I still use some of them ones I bought back in the day with a heavy discount.
@@AVTAstro , oh their good. Just not any better than what you can make yourself for much less. And your instrument?
