Hello,
my car amp is defective, so I need schematics from the amp. or one info: There is a little pcb with the driver transistors and one IC near the fan. I can not read the Type of this IC,cause its burnt. Please give me Informations how to get schematics of this amp or the type (name) of the IC.
Thankx |

I believe the IC is an NJM4580.
Schematics are difficult to get. Some manufacturers will provide schematics but the driver board is generally a block with pin-out descriptions.
I've repaired quite a few of these (not lanzar, clones - planet audio, power acoustic...) but I've never seen that IC damaged.
If you need values for any of the components on the driver board, let me know. |

Hello Perry,
I'm very pleased about your answer. I think you are right with the NJM4580. I can only see the first 4 and the last D (DIL Case).
Today I've ordered the new components and next week beginns the repairing. Is it true, that the C1027 transistor is not a 2SC1027, but a KTC1027 Type ?
Thank you very very much from Germany! |

As far as I know, the 2s and kt are 'generally' interchangeable. For example, the KTA1266 and the 2SC1266 are the same.
There are exceptions. The 2sc1027 is a 50 watt transistor while the KTC1027 is a 1 watt transistor.
I think you have to look up both parts and use good judgement when sourcing replacement parts. |
