Vintage Mixing Console Restoration - repair and expand the KSG625 from 1972!

[@alicee_music]

Wow that's the craziest diy project I've seen on here! So excited for your future designs:)

[@dolovfm]

Nice project - My unfinished modded KSG625 is 18 into 6 into 2 with 6 eq's and 1 limiter. I am also using 3 Neumann PSVE''s for 4 aux and main stereo summing.

Hey Marc, cool project! I did something similar with my KSG625 w/ output transformers. Let’s compare notes!

[@ryand6502]

Great work! Im glad to see an old console come back to life. A vido on your In/Out and Meter driver PCB design would be very helpful for my console restoration. Take care!

[@MikWhitnall]

Really impressive man.Over the years I've seen these consoles and wondered why they were much cheaper than other desks. It sounds fantastic. Wish I had your skills.

Well done.. amazing project. Be excellent to your girl... Most don't understand our obsession with audio. So .. look after her ... love ya work.

[@MarcHerwig]

Luckily she is a musician too. Not so much into equipment, but she understands our love for gear and supports it.😃

[@jeanyvestheriault8362]

Great work man! I mean both of you of course.

[@WatisYouth]

This console is so well thought out! I want one!

[@ghostexits]

I'd love to see how you managed the Solo/Mute bussing, and any other bussing that you added to the original channels. Very impressive work; I remember seeing this console for sale and wondering how someone would go about rebuilding it.

[@mikeclarke3275]

Loved this video. I'm rebuilding a yamaha mixer now. This video is a great example of what can be accomplished with a bit of modernization. Please make additional videos on the boards added, and level marching technology. Please include power supply.

[@MarcHerwig]

Good luck with your Yamaha mixer! 👍 I plan more videos where I will go more into detail, especially how to design your own power supply.

[@first.take.studios]

that looks amazing!!! i would love to see a video of how you did the 500 series part to the mixer!

[@Suburbstudio]

sehr nice

[@shoetiquemusic]

I like what you're doing here! Well thought out video, good pacing and plenty of great shots of the console. Looking forward to your future videos!

[@MarcHerwig]

Thank you!!

[@olavfossheim3288]

Wow ! Good Job !

[@jakomostyn7123]

This is very impressive!!

[@josephandrewvictor]

Sweet! Great job!

[@buhlir]

Holy shit dude!! Like wow, you've got some skill man, I would love to hear more details, like diving in more on the electronic parts you had to get, and where you found them. and maybe just some deeper explanations on your electronic builds. I just bought a Tascam M50 from the 80s and want to do exactly what you did here basically. I am obsessed with everything 70s, and have been chasing that era of sonics for years. I found out that my desk is a transformer-less design after I bought it, but I really Digg it, I am just thinking about adding trans to every channel. To make it sound more seventies.

[@doulos5322]

good job man!

[@MaxSchwanethal]

Woah

[@MarcHerwig]

Thank you! 😊

[@cristiannec9116]

Great work Mark! I recently bought a Siemens C4 without power supply and I intend to build a proper PSU for that beast. May I ask for your advice? Thanks.

[@MarcHerwig]

Oh great desk! Congratulations! I plan videos about more technical stuff and also how to design your own PU. :)

[@kamuua]

Great project! But most likely there are problems with the VU meter. This is a stereo (not balanced) connection, and at the same time the VU has a phase shift when the signals at the stereo input are unbalanced. Mono VU meters would be better. They are more expensive, but the accuracy and independence of measurement is better. Good luck!

[@RockMixerMusic]

Wow this is cool!

[@lukasstandl4424]

Servus, ich plane gerade mir die perfekte Konsole zu bauen daher bin ich auf dein Video gestoßen da es meinem Projekt am nächsten kommt. Ich will eine Art “hybrid” console. Analoge pre Amps, analoge eqs (500 Series) und unter fader von einem daw Control unit z.b icon qcon. Wie hast du die einzelnen 500 Series Teile einzeln auf die fader bzw. Pre map weiter geleitet? Ich seh die ganze Zeit nur die 500 Series racks wo alles in einer Schleife zusammen läuft. Hast du da ein rack? Oder alles selber gebastelt? Lg würd mich auf deine Hilfe freuen! ✌️😌

[@leostampfli1440]

Nice! Wie hast du die EQs gebaut?

[@MarcHerwig]

Die EQs sind Teil des originalen Pultes. Die habe ich so gelassen und nur restauriert (also neue Caps, Schalter gereinigt…)

[@andreaslorunser4112]

die armen trennklinken. das herz blutet. aber gut gemacht.

[@MarcHerwig]

😃😃Ich schicke sie dir gern zu falls du Verwendung dafür findest.
