Bat Vk200

Hi BEN GOH

I wonder if you have sorted out the problem with your BAT VK-200 as I have exactly the same problem about my same model amp blowing fuse on the left channel.

In the end, with the aid from someone.

I replaced all the mosfets and I have to disable the protection

circuit to bias the amp.

The set is finally working.

Hi BEN GOH,

It's me again and many thanks for your reply.

Please could you tell me roughly how much did the repair cost you.

I know someone who can repair my amp but I'm still trying my best to gather info about what exactly needs to be done. This site is excellent in giving me some info but I can't seem to find any site that can provide the schematics.

It is such an excellent amp to be left unused and it would be great if I can have it fixed. You are lucky to have it working again.

I want also a schematic. Not for service. Only for information. Block diagram or simplified schematic is enough. Perhaps it is one of the topologies by post #1 about
