Awesome AVO tester bro, I have the MK IV & it's rotors are also diabollical! very tight:(
Thanks
Hope you have a good break, and manage to get some time for yourself! Don't work too hard, it's not good for you!!
Thanks.
No time, join the club.
A well deserved break. Looking forwards to a resumption of “normal services” .
Enjoy a well earned break!. Take it easy.
Zero technical content? Hope you're not trying to rival me! 😁
Hahaha 🤣
Enjoy your vacations time! and.....come back to us in september... tears
Enjoy your break mate
I just wanted to say thanks for taking the time to post this video. You prevented another TV ending it's life in land full. I fixed my TV in about 5 mins. I didn't realise how easy fixes can be.
Excellent work Laura. If only they were all that easy! Thanks for watching.
It’s a hit!
Haha
Great Video as always, Hopefully my Meshtastic gear will arrive soon and I can actually get some stuff working properly that isnt lashed together in the shack - And we might actually then hear each other!!!!!
Fingers crossed!
とても役に立ちます。終わりまでは大変素晴らしい動画です。お疲れ様でした。👍
Thank you for your wonderful comments
First of all, I would like to apologize. I watched it till the end. This is a really great video. No, thank you to all the repairers around the world.
Thank you 🙏
Perhaps you can answer an age old question? I used to know somebody that had the same Panasonic TV. He used to insist that it had 4 guns RGB + Yellow, the logo showing 4 colours and name Quintrix seems to perpetuate the idea. I assume that the set does NOT have 4 guns, so what was the 'Quintrix' all about?
Marketing guff. Sony (who actually did have something a bit different) had Trinitron, Sharp had Linytron, Mitsubishi had Blue and later black Diamond (again something a little bit different). All trying to get a USP
Hi mate been trying to get MTK952 TX & MRK980 RX on Wisy manager. All on same subnet as pc and I can ping them but they weren't showing up automatically. Turning off the master firewall settings on the pc solves it but not ideal for long term. Can you advise how I enable them through the firewall while keeping the master on to protect the pc. Cheers
Yikes. It's been 2 years since I worked with Wisycom. Things change fast, give Raycom a ring.
Wait, I didn't know about the stereo output jack and the matching amp! Thanks for that!
I have noticed our organ seems to go out of tune every few months. Very picky.
The oscillators should be stable. Check those caps in the PSU under the bottom, and the caps on the master oscillator.
@@AndyDoz Will do right now. Is it easy to explain the location of the master oscillator? I thought the temp was changing my tuning...lololollll
@@alishatruman study the video. It's on the top, far left from the front. I had to fit a surface mount cap in there, as the original is long since gone.
@@AndyDoz Brilliant Andy! So the master oscillator per tone generator board or of the out of tune board...every in my case
Love the old-school diode-chain "buck conversion"
K.I.S.S. applies!
I wonder if it'd be possible to use a system like how the triggers in some modern videogame controllers work, where they have an analog travel until you hit the switch at the end, as a way to detect false inputs from tremors.
The trouble is, I think I'd be bouncing on the switch....
Thank you, Doz!
what a weird voltage requirement, considering as you've said that radio equipment runs at lead acid battery voltages. I saw the "mistake", God I hate doing that myself, and butchering the connector all up. I think a small 3d model on the manuals would clear up this confusion for good.
Weird and ambiguous! The worst!
i hope you can get your tremors sorted out I really enjoy your content
Layden jar 🫙
?
Cool tune!
Hi Doz do you do this full time? I ask this as I was in the trade for about 25 years
Not anymore. I gave up in consumer electronics back in the mid 00's... moved to broadcast, and I now design flight electronics for space craft.
Good result 👍
I new it was DoZ - the song is about him and it’s wacky and he doesn’t get a copyright strike! Multi talented electronics wizard - musician - video producer - and all round creative. 4 big YES’s
Steady on !
What’s the track playing ? Sounds like Heaven 17 ?
It's a bit of me, and a bit of AI
I wonder if that transistor is so that the unit can shut itself down when the battery is low to protect the Lithium pack?
I wondered that, but it's not, the BMS (such as it is, it's 2S with no balance wire) handles under volts. I think it may have originally had some sort of remote control or standby catered for in its design.
@@AndyDoz Posssibly, maybe the same board is used in another unit.
@@adamdavies163 the other thought I had, was maybe a noise gate, to shut the amp off until a signal is used again. The undervolt doesn't make sense, as the blue tooth & preamp etc. is still on.
@@AndyDoz Maybe, or to protect the amp from overdrive situations. As it happens it just acted like an unintentional fuse.
Mine came with not useable hardboard Cnc puzzel. Is the firmware upgradeable?
It did take some working out! I've not attempted, nor needed to update the firmware.
excuse the invasion of privacy but you are a bit shaky - Parkinson's is treatable if discovered early. Sorry if you are just wobbly. Worth it though.
Thanks for the concern. I've suffered since I was 14, but it is getting worse. I have consulted my doctor recently, and I have an appointment with a neurologist in a few months. It's a huge frustration and embarrassment. Thanks again.
@@AndyDoz Ah, sorry to hear. Glad you are looking into it and don't feel down, your hands have done so much more than most.
If I had enough of the big ones like 6000 puffs I think they have 18650s I wonder if I had 30 or 40 could I make a power brick for a bike
Great video. It’s always worth smearing some EHT silicon grease inside the cap only a light coating to stop tracking in the future.
Certainly with those horrible stiff caps like the Philips kt3 triplers. This was still super flexible., and thankfully nobody uses those awful portable gas heaters that used to fill homes with condensation!
Philip's dry joints go back to their PCB transistor radios in the 60s not to sure why their production process was flawed in this way.
Lovely little set. I remember the dry joints well. My old boss would tell me off for going around the boards with my soldering iron. If the joints were done well, you rarely saw the set back. Maybe that's why he was so gruff, lol. We also always had a stock of NICADs for them. I do remember a few flat tubes on these in the 90's. BTW I love the little vigniette at the end...... It's nice to see a little bit of fun :) Carry on the good work :)
My late friend Roger always used to say "Don't take life too seriously, you'll never get out alive"
@@AndyDoz Wise words.... My old boss Tom was of that frame of mind and relentlessly wound me up because I was so uptight and serious as a young man.... Thank heavens I relaxed a bit!!
6:22 6:23 That's a 14" 37cm tube set not a 16" which would be 42cm as denoted by the model details also the 16" had hand holds in the sides of the cabinet . Looks in nice condition just like I remember unboxing them when new in the 80s. CTX e = European CTXs =Singapore I think
Oh yeah, weird how it looks bigger than the 14" TX9 from last week
I've a few of them sets from portable to 20in
Oh, by the way...... Try drinking coffee instead, the dust isn't as noticeable!🤢🤦😁😬
So, did that come out after the 16" portable that used the KT3 chassis? The styling looks older than the KT3, but I bought my first KT3 in about 1981 - brand spanking new from Valance's...... Do you remember them? I should still have a couple of KT3s kicking about somewhere - one of granddad's favourites, and I'm pretty sure I've had more than one or two of these ones pass through my hands, trying to earn a shilling or two to ease my passage through university.
Nice set! Dust in the tea? No bueno!
It has a Philips CTX Chassis they where very good
Nice clean set 👍
ooh thats a nice chunky set
I’d be interested in purchase, when will you be selling it
I advertised it on Facebook. It sold last week, sorry
That looks familiar, although my recollection was that ours was the 14" version. Philips / Pye made some excellent sets back then.
New sub here 😃
Welcome!!
