In Topic: XTi1002 Dead CH2

21 September 2014 - 10:35 AM

In the XTi (and offcoure DSI and CDI) 2000, 2002, 4000 and 4002 when experience defective drivers it could also be a fault in the tracker circuitry.
When the tracker FETs are short the powertransistors and driver transistors worked all on the highest voltage. Usually the driver that is located
between the two heatsinks will fail, so i think it has something to do with the rising temperature of the driver and power transistors and the driver
transistor run out of it's SOA limits.

I tought this topic was the best place to share my experience and toughts.

In Topic: Micro Tech 1200 "Supply" vs. "ODEP" LEDs?

I have seen and repaired very much Crown MicroTech amplifiers (started with the first grounded bridge amp, the MicroTech 1000) but i also never seen one with 'supply', it was always ODEP. If you can post a picture, i'm also very curious.

In Topic: Crown K2 runs very hot. Is this normal?

Hello Alain,

Thanks (again) for your input. When i disconnect the XLR signal cables or turn the gain controls fully counter clockwise
the amp goes into sleep mode on both channels. The enable led dims, and both channels are cooling down.

So i think the amp is working fine.

BTW: the K2 sounds great!

Last week i recieved the last part (the K2 transformer) so the order is completed now. If you want something good it takes a lot of time :D :D :D

Maybe the ribbon cables from the input board to the mainboard?

I do'nt know for sure, but are the output devices recieving there supply from the heatsink? And recieve the heatsink supply from the PCB? I remember there where some models with bad connections between PCB and heatsink.
