Casio CZ/ VZ/ FZ - Pro Series

Hello there! I´m restoring a pretty beat up CZ-3000 I bought for about U$S60. I´ve replaced all the touch switches (yes, all 60 of ´em!!!) and the volume fader. I´m trying to find yet the dual 50K slider pot for the chorus volume that also needs to be replaced. The main problem is that the output sounds very distorted and fuzzy even on the "cleaner" sounding patches such as Electric Piano or Flute, I´ve seen on other posts that some folks had the same problem and perhaps could be fixed by tweaking some trimmers inside the unit to reduce this kind of unwanted distortion. I could not find a CZ-3000 service manual, I´ve found the CZ-1 and CZ-5000´s, which have slightly different measurement values to shoot for: 

CZ-1    DAC Offset Voltage Adjustement: measure -3mV (+/-3mV) between pin 13 of DAC BA9221 and pin 1 of opamp TL082-1
CZ-5000 DAC Offset Voltage Adjustement: measure  0mV (+/-3mV) between pin 13 or 19 of DAC BA9221 and pin 7 of opamp TL082-3

CZ-1    Volume Adjustement: While depressing the A3 key measure 340mV (+/-20mV) between ground and LINE OUT terminal with a paralleled 47k resistor (register)
CZ-5000 Volume Adjustement: While depressing a key (any) measure 360mV between ground and LINE OUT terminal

Which one should i refer to? Anybody has a CZ-3000 service manual or knows its calibrating procedures? Looking at the schematics the pins for the DAC Offset adjustment are the same as the CZ-5000´s but I dont know if the value should be the same...I´ll appreciate any help!!! Thanks!!!

Hello Leandro, if the distortion occours when more than one note is played or 
increases if more notes are added, the problem is the DAC offset... I´ve heard 
that it´s possible to adjust de DAC offset voltage by ear, you just have to 
locate the trimmer.

Either of them.  Try both and see which works best for you.  Bear in
mind that one value is within the spec range of the other!  So the DAC
offset (-3mV +/- 3mV), 0mV would be within spec anyway...

It won't make a lot of difference in any case.

Considering that the 3000 and the 5000 are sister models (identical apart from the 5000's sequencer) and were released at the same time, I suspect that the 5000's parameters are more likely to match those of the 3000. The CZ-1 was launched a couple of years later and while it featured an upgraded version of the same architecture, I doubt that the electronics are quite as similar.

I agree with Simon. I know that the CZ-3000 responds to CZ-5000 sequencer memory dumps and it has the capacity to store sequencer dumps as well. Based on that I just assumed that the CZ-3000 was a CZ-5000 without the sequencer interface.

Out of curiotity, I am wondering how much you are spending to service the CZ-3000. It sounds like you are spending more money to recondition the CZ-3000 than it would be to have gotten one in working condition.

Also, could you upload the CZ-5000 Service manual to the files section? I would be interested in seeing that. 

Thanks.

Steve

On my CZ-1 I adjusted the DAC offset by ear, it's pretty obvious where to set it for a clean sound.

Thanks for the input guys, I was thinking about using the CZ-5000´s values, since the 3000 it is really a 5000 minus the sequencer...
Steve: Not really, until now it has been quite a deal, here in my country a working condition CZ-3000 in my country sells at aprox. 1400 pesos (U$S350), I have spent U$S 60 on the 3000, plus U$S 15 on the touch switches and faders. The replacement work was done by myself since I can handle the soldering iron pretty well( a bit tedious work, each switch has 4 solder points, so I had desoldered/soldered like 500 times!!!). Regarding the CZ-5000 service manual, it is nearly 45Mb. It´s ok to upload such big files to the group´s file section?

Hi there!

Leandro, yo también estoy en Argentina. Felicitaciones y suerte con tu 
CZ. Imagino que lo habrás comprado por MercadoLibre. Yo estaba muy 
encaprichado con pegar un CZ-1 desde hace años... tuve mucha suerte y 
compré uno por ML a 950 pesos en junio de 2010, me lo mandaron de 
Neuquén, en excelente estado!

Es cuestión de buscar, esperar... aunque, claro, CZ-1 hay pocos.

Cualquier cosa, a tus órdenes.

Saludos!

David

Daniel: the distortin occurs with only one note played. i´ve been probing the circuit and found that one of the TL082-3 (the one nearest to the DAC) outputs (pin 7) is considerably louder and distorted than the other (pin 1)...I´ve replaces the opamp but it wont change...I´ve uploaded the CZ-5000 service manual download link to the files section, I hope that this makes things clearer and maybe someone can help me fix this. Cheers

Hola David, yo estoy en Cordoba y te cuento que al CZ-3000 no lo consegui en ML, se lo compre a un personaje que lo habia usado para girar con una banda de cuarteto (asi que te imaginaras el estado en el que llego a mis manos: una tecla partida y parchada, quemadas de puchos en el chassis, faltaban botones etc etc) pero lo pague solo 240 pesitos! Ya le reemplace todos los switches y el pote de volumen y quedo joya en ese aspecto (50p en repuestos), pero sigo luchando con el problema de la distorsion en las salidas, a la tecla partida la consigo en un service oficial que hay acá, pero me quieren atar 50 pesitos solo por la tecla! Imaginate para repararle ese problema de las salidas...por eso queria ver si con la ayuda de la gente del foro lo puedo solucionar yo (ademas tengo algunos conocimientos de electronica), por eso subi el manual de servicio del 5000 (que es el 3000 mas secuencer) a ver si alguien se le ocurre algo, vamos a ver si lo saco andando 100% pronto, saludos!!!!

Leandro,

I had a CZ5000 that was doing this same distortion thing and it wound up being one of the uPD933 voice chips was bad. I bought a used and abused CZ101 main board on Ebay and used that for a donor. Now it plays fine.

Since there are two voice chips see if the distortion is on all 8 notes or just 4 of them. Take a single line patch. Play one note then two without releasing the first note. Keep doing this until you have all 8 notes held down. Are all 8 notes distorted? Lift the power leg of one voice chip and then the other and see if it changes. Hopefully you'll get the proper chip one the first try if one of them is bad. My luck was the wrong one first try. Oh well....

Hola, Leandro. Bueno, yo pensaba que lo habías pagado 1400 pesos jaja! 
No hiciste mal negocio, entonces.

Mucha suerte con las reparaciones!
