CROWN 2400 amplifier restoration / 24 transistor amplifier restore

[@sareas3294]

28:32 "restorated" amplifier 29:09 different amplifier

[@MoparStephen]

Say it ain't so - a restoration video on KZbin that is a fake?!?

[@tyronenelson9124]

Different label on the front.

[@DerekHundik]

@@tyronenelson9124 29:09 FAKE FAKE FAKE its different amplifier The old "restorated" one has 3 orange diodes on the top and new one has light green. The scale on the two knobs are longer on new one is shorter and its says level the "restorated" has no level written on it. FAKE FAKE FAKE

[@DerekHundik]

ale koles scieme zrobil dwa rozne wzmacniacze tej samej marki. Stary niby "odrestaurowany" ma na górze 3 pomarańczowe diody, a nowy ma jasnozielone. Skala na dwóch pokrętłach jest dłuższa, a nowa jest krótsza a nad pokretlami napisane Level , ten stary tego nie ma. Co za sciema.

[@gglegreff1858]

Oui, faux, les poignées ne sont pas les mêmes : original...choc a la gauche Nouveau....rien, problème ?

[@lebakaify]

Judging from the scars on the left handle of the front panel, the last test machine was not the same machine at all

[@AtanasPaunoff]

I also noticed that in the end when he closed the cover transistor wasn't soldered at all...

[@mikem2k38]

Also the faceplate is a different color and the knobs lost their black inserts. The resistor being soldered where a zener diode goes takes the cake!

[@jetblakink]

Well spotted!…

[@aspjake123]

Amazing rebuilds. How in Gods name do you remember all the connections going back! I would be lost and hooking up wrong wires.

[@wraiths_]

He reviews the videos?

[@McTroyd]

Those amps are beasts. That one might still have worked somewhat in its pre-restored shape, as long as all the blown transistors were pulled out. Post-restore, should work well for years yet. 👍️

[@SangTran-iu7ih]

hhh

[@puciohenzap891]

They have one stupid problem though, they won't function without that motor-fan being operational.

[@McTroyd]

@@puciohenzap891 Didn't know that, but it makes sense. The underlying amp technology wasn't necessarily the most efficient; there'd be a lot of heat to dissipate. I prefer the protection mode of "attenuate the amp based on heat load," but I guess a safety like that is better than nothing. Must be a headache during a live show though.

[@whynot6795]

Pre restored worked (at least led' are binking). After rusting in chemicals and puliing out transistors its only for trash.

That was the holy relic back in my days of sound reinforcement.

[@MrJef06]

Brings back memories too. I still own a MA1201 I bought second hand some 25 years ago. Works like a charm (although I don't use it much anymore).

[@MrSmi31093]

The man has done took this huge amp completely apart, cleaned it up or down, painted it and put it all back together and tested it and it works great. I go lay down now!

[@josuebalam5119]

Buenas noches si le dieron su mantenimiento a los de usted acá en Yucatán..? También soy de Yucatán y tengo uno que igual necesita su buen mantenimiento pero la verdad no sé en dónde o con quien

[@catalin-constantin4197]

You did a awesome job restoring that amplifier 👍

[@whynot6795]

Restoring?

[@micrometer1484]

That's a quick way to solder through hole components! I suppose whatever works, instead of the longer process of soldering through the hole to the trace side. I also noticed that the working amp doesn't appear to match with the restored one.

[@nitroboy2]

i see , the left handle is magicaly fixed

[@re-fix9678]

[@tomjohnston9794]

I was a Crown authorized factory warranty tech for years in music stores in Austin..Repaired many of those and the older ones and the micro techs too..A curve tracer makes troubleshooting a breeze instead of a DVM though..The old DC#))'s did just that..they DC straight into your cab when an output shorts...Peavey CS800 crowbar protect circuit was the answer, we built them on small cards to for in the banana jacks on those..fun stuff.

[@THEtechknight]

That crowbar circuit on the CS800 took me for a ride one time when I was just getting into amplifier repair as a teen. Theres a couple concerns in this particular video though. He doesnt show the replacement transistors, only soldering in the old ones and not showing the replacements. And then at the end of the video it looks like a completely different amp with the sticker looking new..

[@connerlabs]

@@THEtechknight Yeah I was watching to see what he used for the replacements, the Crown output transistor is just a rebranded MJ21194 or MJ15024 or something IIRC?

[@josuebalam5119]

Tengo un crown2400 macrotech tiene el problema de que la encenderlo un canal no enciende el LED rojo y me saca el audio ruidoso ronco y bajito no sabrá cuál sea el problema..?

[@felixdirmeier]

Hey is there a way to contact you on some questions? I have some old ones left and im not to this are there any things youd change in general after this time?

[@eliseoflores9192]

It's amazing how you took it apart and put it back together, I did it but I only took half of it apart.

[@tei0930]

Kereeen juga ya tuh amplifier Power badak pada masanya mungkin yak

[@Afterburner]

I was curious if you used heat sink compound with those power transistors when you replaced them? Great video!

[@AstrosElectronicsLab]

He did, but nowhere near enough.

[@propanbutanovichmetanov5950]

when you know that you will never turn it on you dont need any compound :)

[@josemanuel2724]

És um grande artista fizeste um bom trabalho parabéns pelo seu trabalho obrigado

[@mitchnn]

The final assembled unit is not the same one as the workin one turn on at end. You can tell by comparing the front unit decal. Upper right corner has a slight missing cut on working unit, but the non working does not. The knobs are not the same. The marking on the final "restored" assembly has red deteriorate dial marking, while final working does not. Finally, I don't a single 1k ohm meter setting enough to trace through that troubleshooting. So you had 2 to begin with, one junk amplifier never intended to be "restored" as a workin unit and one working one to show at the end as working unit. Well,... at least there was a good job cleaning and painting.

[@wraiths_]

Maybe he had another working unit

[@jt.rewinding6533]

Always watching sir

[@cesars4445]

Nice restoration job Mr.Electricity congratulations... is a hell of detailed work. Not sure if the restored amp ever worked, since the tested one seems to be a different one.

Excellent job, Master.

Автор, я тебе лайк поставил за то, что не отказываешься от работы, но есть нюансы в твоей работе: Во-первых: ты не обновил оловом некоторые закисленные контакты Во-вторых: после покраски я увидел, как краска обуглилась в некоторых местах корпуса. Если делаешь работу, то постарайся, пожалуйста, сделать это максимально красиво и качественно. С уважением, от подписчика, который любит твои работы.
