Hello,

I want to refurbish/rebuild my Nytech CA-202 and need the schematic or Servicemanual, but I can only put my hands on the CA-252 schematics (which differ a little bit) and the 202 amp part (from tiefbassuebertr).
Can anybody please post or email these schematics or Servicemanual?

Thanks, Carsten

Hi,

Your circuit may not be very different from this one :

Your question gives nothing to go on. How about telling us what general condition the amplifier is in, whether it appears someone has already messed with it etc. inside, as usually seen by messy work around the power output transistors.

It seems common with amplifiers at bargain Ebay prices, that it means the unit was too expensive to repair. With a few lies about its repairability, the problems and costs then become the buyer's, whether it is then repaired professionally or they struggle with the problems and steep learning curve of electronics practice and repair techniques themselves.

So, do you have any prior experience with electronic repairs, soldering iron, suitable hand tools, Digital multimeter and access to reliable, quality components? With some measurements by you and the aid of a schematic diagram to trace the circuit properly, it need not be a disaster but you'll need to give us some facts on which to base suggestions first.

There is no free service manual available but this schematic is a little more readable than the above: http://i.imgur.com/FSGjKSa.jpg

I have a CA252 Nytech Audio amp and need to rehouse it. I need a copy of the circuit diagram for the AMP.. does anyone know where i can replace the diagram I had. I did work for the company back in the 80's but i have lost the circuit diagram. The one listed here is not correct for the CA252.?
 
Sorry Ian,
I never had originals, these are 'off the net' and the best available that I have seen. Also, I have no idea who posted them originally, they appear with different titles from time to time, but are the same quality...

Fortunately, once you have any of the modules in front of you, they are well marked with component numbers and it is (fairly) easy to trace out the circuit and component values when fault finding.

i have one cta 250xd and one cpa 602.
they are very easy to find on the circuit and repair
on the other hand, pay attention to equivalence of transistor, the two mine do not like, it was necessary that I find the original reference

Who could have the genuine service manuals for all models of the vintage series like integrated amp CA202 ?
This URL's don't help.

Please note: I am not looking for this for repair purposes but for a collector of Nytech' vintage series.
Thanks for an advice.
