First gen Kronos 73 key is pushing 7 years now. If she bites the bullet I'm gonna be angry. You don't want to see me angry! Evil


There's a big bunch of us 7 yr owners, a variety of ' mileage' on each original
K

I haven't had any problems- mine is somewhat low mileage. Just the same the components are aging. Heavy K use does not seem to be a factor with the internal computer type components, mobo, etc.

I estimate us 7 year owners are fine for another year. Seeing anything beyond 1 year is almost impossible, anyway.

The only area I am concerned about is the keyboard mechanism- the various parts take a pounding and the contacts might exhibit wear. I have a local friend with a 73, heavily played and he is forceful, fat fingered on his keys. His 73 keybed exhibits heavy wear ( hard to describe, its uneven).

I'm nowhere near as heavy handed as I used to be. I took a break from weighted keys for more than a decade and got very used to the basic unweighted key machine. It had a lot to do with budget and the fact that my old Fender Rhodes Mark 1 bit the dust. That and not having a real piano anymore. It did take a bit to get used to the feel of the K73 but I really wanted to get back to my piano playing. There was a time when I used to break the tines in my Rhodes. Now I just wear out my hands!

The thing is, out of all of the keyboards that I've own over the years, my Korgs have seemed to stand the test of time the best.

The one that didn't was my first Korg Wavestation but I found out that it was because my case for it put too much pressure on the top of it and actually caused the internal motherboard connections somehow to to a shield inside. Myself, I think it was just a flaw in the manufacturing of that particular one but it was getting bounced around a lot when I was on tour for 3 years in the nineties in Europe. My next one has never ever shown any flaws. Korg keyboards are great.

I go way back. I had the Rhodes Staqe in '71:

The Rhodes keys were like frozen mush. I had poor piano technique as I was
mostly playing B3 parts. Self taught.

I never mastered that Rhodes and sold it in '76 shortly before moving
to CA ( SF bay area) from Chicago.

I can handle the Rh3. No wizard, though.

Believe me, I'm no wizard either. I did start out by taking piano lessons when I was 7 way back in September of '62. I took lessons for just over a decade.
My Mark 1 had a sluggish action to it too. But I was a pounder way back in the dawn of time!
I guess you, like me also remember the day when electricity was finally invented! Youngsters today! I tell ya. They just don't know how easy they have it! Wink

My dream is to find a time machine and take my Kronos with me to 1972 Smile

I tried looking around and can't find a used one. Korg says it's no longer be produced.

This seems highly illogical, since they continue to manufacture the new K2. I seriously doubt that Korg is out of replacement components which continue to be installed in new units and still selling them in good amounts.


Exactly.

So why do you need a new board, as opposed to repairing said board at a component level?

Another thing to keep in mind is that the number of spares produced may not be based on the total number of repairs expected, but rather the total number of faults that cannot be repaired at a component level and genuinely require a whole-board replacement. That's why there's a parts listing in the service manual Wink

Welp. Mine caught on fire. No joke... There's about a 1/8" hole in the middle of it and half the components are destroyed. Not sure why or how this happened.

I fix a lot of vintage synths, so I'm all about repairing what I've got, but this pbc is beyond saving.

Ask the Korg service if they can replace it instead with a KLM-3360 (the one that is now installed in the K2s). I'm just speculating here, but maybe the KLM-3360 is in all points electronically identical to the older KLM-3002, except that it is lead-free (new PCBs must now respect this in almost every country and maybe this was not mandatory at the time the KXs were made). In other words, the older PCBs might be hard to find, but maybe the shops have plenty of newer lead-free ones.

Another possibility is that indeed the older KLM-3002 differs a bit from the K2's KLM-3360, but if so they would normally update their service manuals as connections and components would differ, and this doesn't seem to be the case (again, I'm speculating but you have nothing to lose to ask).

Take a look at one of the pics I took from mine when I did my custom color LEDs mod last year. At first sight, do you notice any obvious differences in terms of components, connectors, etc. ? If it seems identical, I would definitely ask the Korg service about getting a KLM-3360. I have a couple of other pics if you want to check them too.

Hope this helps.

Very helpful! Definitely looks comparable and I'll have to do some research on swapping them. But....good news! Korg just contacted me and said they found a board. It's being shipped to me next week. $275 + shipping. Thanks everyone.

Hi there,

Glad that Korg could solve your problem. Dancing
