Joe’s diagnostic skills continue to amaze me. I mean seriously, he’s not even in the room and he knows exactly what the problem is!

[@gregoryclemen1870]

I have noticed when "joe" does get "STUMPED", he knows how to dig into the problem and not give up. he has really good trouble-shooting skills, and if you notice he always has his best friend with him------- the" multi-meter", and a good knowledge of system function, and a good set of eyes!!!!

[@GeorgeZ213]

To my memory, neither have any official tech/electronics schooling. They do all of their diagnostic wok 'seat of their pants'.

[@markjackson1444]

I read or was told something that has served me very well over the years. … It was “the greatest diagnostic tool you have is … your eyes” I have found this to be absolutely true, and I notice that it works for you too Ronnie. Great how you managed to work out it just wasn’t sitting right. Problem diagnosed by: your eyes! The eyes have it. Great series of videos. Thanks for the education Ronnie.

[@SpaceCop]

Your eyes are just optocouplers. you really need the MPU in your skull casing working to be able to turn that into anything meaningful.

[@katenunyabizness9221]

Good thing Ron's so humble as well!

[@DoctorDetroit100]

Ron got me when he tried to take apart the old micro switch. He knew the right thing to do, he fool me again.

[@mfranzusan3014]

This series is proving to be very interesting. Thanks for uploading Joe and Ron!

[@LyonsArcade]

Thank you for watching Mike, the jukeboxes are very cool and fun to work on.

[@andymouse]

Purple Rain on purple vinyl how cool is that ! nice catch with the switch....cheers.

[@tpafl]

Outstanding presentation. Step by step through the thought process as well as mechanical troubleshooting. Appreciate your help!

[@LyonsArcade]

I'm glad you enjoyed it!

[@dh-_1011]

Caps filter out low frequency, like a crossover network. Lovely video, btw!

[@LyonsArcade]

Thank you for watching Dh-1011!

[@OhRonaldo]

WHAT A GREAT CATCH ON THAT HOME SENSOR! I haven't finished watching yet but I just needed to shout that. Awesome catch Ron. Definitely entitled to a moment of thumbs under your suspenders!

[@OhRonaldo]

Hahahahahaha! I loved the pause after the screwdriver slipped. That's the "Am I bleeding? Does it hurt?" pause. Then the explosion of the switch. Classic Video Game Repair moments!

[@LyonsArcade]

Sounds like you've been through that before, LOL

[@OhRonaldo]

@@LyonsArcade Yes, usually after subbing my toe, Ron. I stand there, ask the questions and based on the answers decide to either limp or hop back to the couch

[@AllanSitte]

Fine work as always sir! Thank you for sharing all that you do to fix stuff. I definitely appreciate the home built keypad. Fixin things that are broke!!! Gotta love it.

[@davidhollfelder9940]

It puts away/stows the records better than I ever could😊. I nicknamed the record cassette the pill bug (rolly-polly).

[@naytch2003]

Haha thanks for the shout out Ronnie😁

[@Fatal_Jinx]

When you fixed the wheel 🤣🤣🤣🤣 I had a good laugh.

[@macdaddyns]

Ron, chuck the haters, yup,yop,yup, you are that good. You are way to successful in getting results to be that lucky. I used to be a computer tech and I can tell you there are not many people that can do what you have pulled off even with the right schematics. Well Done!

[@LyonsArcade]

Thanks for watching macdaddyns we appreciate you hanging in there with us for so long :) The trick is to not take yourself too seriously, it helps you stumble into good things in life

Say it once..say it loud...I'm the Naytch(Grinch) and I'm proud 🇦🇨😆

[@brand-x7049]

Caps filter low audio frequency, coils filter high frequency. The caps on the upper speakers are there to filter out bass, and there are probably coils on the lower ones to filter out treble.

[@bperkins]

So I'm talking (loudly to KZbin like a dope) to you at the 18-19 min mark. You have a bolt with a spring that is the adjustment for that board. Looks like a 3/8" wrench to adjust the pivot point for the optical PCB, No? Always fun to watch :)

[@saskia6750]

really enjoyed this video guys.....Thank you for the video🙏x

[@quantumleap359]

Microswitches are good for many many operations, but don't last forever. I had an AMI Continental II that would intermittantly burn up it's bow record side select solenoid. It ended up being a microswitch that was stuck in the NC position, which kept coil voltage on all the time when it was supposed to just pulse the solenoid to tell the bow mech which side of the record to play. Replaced the microswitch, (and the solenoid) and it was good to go.

[@iamnoone.]

You da man the record 🧍‍♀️

[@MrKoakai]

My eyes keep getting drawn to the new buttons not being straight. But hey, they work and a better job I most certainly could not do.

[@Jason-lx3zu]

Oh you're just cruisin' for a bruisin' :) It's a first try and it worked great, will be perfected over time. :)

[@1000davetron]

That poor switch..... RIP, switch 1965-2022.

[@LyonsArcade]

I think it actually died about 10 years ago inside, we just broke it apart in 2022 :)

[@senilyDeluxe]

A friend of mine showed me that if you put bad microswitches in isopropyl alcohol and click them a couple thousand times, they work as good as new. Now you just gotta ask yourself the question if the switch is worth your time. In my case, it takes me the same amount of time to locate a matching switch from the bin as cleaning it in alcohol.

[@LyonsArcade]

yes I think it would clean up, but like you said I'm ready to move on to a new switch... and this one was brittle too so it was on it's last legs in my opinion :) I was going to try to clean it if I got it open without breaking it.

[@gregoryclemen1870]

contact cleaner works good too!!!!

[@buddyweiz]

All hail the allmighty Ron! 😉

[@russellgibson3070]

Good stuff as always sir you by any chance have a rockola legends or rowe CD100B, R93 or R92 to fix by any chance? Future projects and love learning about common issues. Thanks again

[@paulclarke7571]

24:19....I was in an elevator yesterday that was playing that tune.

[@ismaelmorales7450]

Yo sigo pensando que estas rockolas transistorizadas son como los carros de inyeccion electronica, se necesita aparatos especiales para diagnosticar las fallas y solo es cambiar de modulos lo hermoso de las rockolas como la modelo 445 es que son como los carros antiguos caburados, son mas analogicas y mecanicas, con amplificador de bulbos, mas sencillas de componer, sin tanta electronica, la rockola 445 se compone solo con unos cuantos desarmadores, dados, lijas para los contactos de los relevadores, un multimetro y ya, la mayoria de las fallas son falsos contactos y muy pocas fallas mecanicos y este tipo mas recientes son problematicas por tanta electronica

[@davidmooney2706]

Capacitor on the speaker is basically a crude crossover which will stop low frequencies depending on the value. Bass driver will be in the bottom of the box

[@JohnEricBooth]

Sent you an email brother. I DO have that schematic!

[@LyonsArcade]

You're the man John, it looks like that may be the only manuals available for it!

[@BeckyGeyer-qs1kw]

I have a rockola model 1000 that has been in climate control storage for one year. When we plugged it in, it played the first record, put it back and the turn table kept moving. It will not load additional records. Do you have any advice for my electrician?

[@pdaddyblake]

You never showed how to adjust the optic coupler looked liked there was a nut on a spring is that what u adjusted 😮

[@1976aztec]

Alright Ron

[@DjResR]

These old aluminium case fluorescent lamp starters are quite rare nowadays. Edit: It's not uncommon for IR LED to die in the optocouplers._

[@gregoryclemen1870]

if you want to keep the "METAL" case, just remove it and put it on your new plastic case starter, they do come apart, or remove the "GLOW SWITCH/CAP" from the old starter and use the "GUTS" from your new starter. the other big problem is the availability of "IRON CORE BALLAST". I have that stuff, I stocked up when they were still available( metal case starters too). also if you have a lamp that is at the end of its life cycle(preheat type) do not leave the "BLINKING LIGHT" in circuit, you will kill the starter/ballast.

[@DjResR]

@@gregoryclemen1870 Availability of these starters is getting low, I have very few left and it are in storage for safe keeping. I have plenty of lights with these ballasts though._

[@gregoryclemen1870]

@@DjResR , what starter numbers are you low on ??? ( FS2,/ 20 FS4/40, FS5).

@@gregoryclemen1870 I have 3 80S-220 (soviet FS-11/S10), one 20S-127 (soviet FS2/S2) and one polamp ZTE-1. Although I have a lifetime worth of FS11-S10-ST111 and PC422-S2-ST151 starters with plastic case. I could use S2s in "two bulbs in series on one ballast" fixtures (230V 50Hz mains here), but it's not that critical at the moment._

[@gregoryclemen1870]

@@DjResR , I did not realize that you are living in the "U.K', I live in the "STATES" where every lighting circuit is fed 120 volts( we do have 277 volt lighting systems- non residential that is fed from a 480 volt 3 phase/ 4 wire wye connected transformer system- the neutral line provides the 277 volts for lighting systems)

You can use a keyboard from a 490-1 jukebox to replace a 496 keyboard....

[@waynegram8907]

The MECH Board has two big relays to turn on the record player and the record changer, but not sure why they used those big 24vdc relays, any reasons why?

[@DjResR]

Reliability maybe? Usually these are used for industrial purpose._

[@waynegram8907]

@@DjResR The Relays aren't switching on/off high current or high voltage, so not sure why they are using relays

[@DjResR]

@@waynegram8907 What it does have is a lot of cycling on and off, even when the voltage and current is quite low the overall long term wear and tear still justifies the use._

[@gregoryclemen1870]

the relay coils are fed D.C. voltage for reasons of" fast pick up time"/ release time due to a diode that is in parallel with the coil blocking the inverse voltage( cuts way down on contact bounce), and the 60 hz hum that can be generated at the relay armature if fed A.C. voltage, esp. if the "SHADING COIL" is open. contact bounce is really bad on A.C. voltage relays, and if you have a relay that uses one of the contacts as a "LATCH CIRCUIT" and the relay only gets a pulse to the coil, it can get missed because the relay did not have enough time to "PULL IN". also , there is no shading coil in a "D.C." operated relay, cutting down on cost.. large relays are used in high current switching applications, such as starting/stopping record platter motors/ motors that drive the record magazine basket, record gripper arm, record tone arm( same motor).
