visonic 900hc question

ampjunkielikeme · 31st March 2009, 06:55 PM

i have a visionik 900hc that has a blown power supply, but the question i have is.
what can i use to replace the sanken c-3856/a-1492's that are in the output section..?? 16 on each side of the amp....

the amp had only one output that was shorted out in the whole output section....
i plan on replacing the power supply with the original irfz44n's , but if you think the irf3205 would work, i could use them.....

The original outputs are readily available.

In an amp this large, you should use the original parts. If there is some incompatibility (may not be immediately obvious), you could destroy a lot of parts.
