Dear Sir,

 

I am in Sri Lanka. My name is Dinesh. Recently I receive Zeck CA1600 amplifier from one of my customer for repair purpose. He has given it to some other repair shop and they were unable to repair the amp. after that the owner brought the amp to me.

 

When I open the amp and observed, both CR153 diodes are missing from the both sides. I down loaded the CA1600 schematic but it has only written CR153 . theres no zener value.

 

could you please tell me whether I have to put 18V zenner or 4.3 Zenner. Or what is the correct zenner voltage . I downloaded Zeck A1205 schematic also. it mention 18v zenner. but on some other models of schematic mention 4.3v zenner .

 

so for CA1600 what is the correct zenner voltage?

 

Dear Sir, your valuable advice will be highly appreciated from our end.

 

please reply to [email protected] in ENGLISH

 

Thanks

Moderator: Did you try to download the service manual from here ? http://elektrotanya.com/zeck_ca1600_ap1800_cap1800_amplifier.pdf/download.html

Edit: it seems that is no way to find that value in that service manual...

Many thanks for the reply Sir, I have the downloaded service manual. on that service manual it is only mention cr153 for that zener diode. if any one have the ca1600 amplifier then he can physically check that zener diode and tell me the voltave mention on it for me please.

 

I am waiting for someone's help. please

Only someone who owns that amplifier can help you, unfortunately.....but i will also try to find the answer for you, on other forums eventually.
