Problem Z1!Help!

[brunogtspl]

Hello,

My DD Z1 amp has a problem during a test spl I replace transistors FQA38n .. and I control the board driver. I change ir2184s 2 drivers, there are 4 zener diode are connected I can not find the corespondance searching on search engines? diodes are marked B2Z or B2L
Can you help me I miss more than its components to re run my Z1. many thanks

I put pictures of the board to see the driver installation!

An externally hosted image should be here but it was not working when we last tested it.

where are those diodes on board on which one?
any pictures?

I don't think b2z or L is correct, are you sure about that mark?

maybe this will help you, from some other user that made this

I have new pictures on B2L diodes or Z are short circuit!
Find this model of diode? Thank you for schemas Luka! there are power PWM

Im trying to find the same diodes since the Z1 i have here they are shorted as well..


If i find a part number i will post it.. If you find one before me id greatly appericate it if you would post the part number..

hello my name is francesco306 and delight in the repair of amplifiers and I came across the dd z1 someone could provide me with electronic schematics amplifier

 

[S Merlington]

Start a new thread and describe the problems with the amp...

My subwoofer is placed in short circuit and made ​​a short circuit in the FQA 38N30 transistors and the card driver. I check the driver board components there are four IR 2184S
B2L and zener diodes are also short circuit! where can you find them? Thanks

Many thanks brandes!!I order the diodes and I will tell if the amp is working?!

They are a schottky diode, the good ones measure .14V

 

[Perry Babin]

If they're using Schottky diodes, that's probably whey they're failing and other diodes in similar circuits are not.
