Default Nytech CA 202 schematic or Servicemanual?

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

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
