In need of a 300ASC or 200ASC

[Shaun0181]

I have a Bowers & Wilkens powered sub with a crapped out ICEpower 200asc.
I cannot repair the board as it is damaged from the heat of a burnt out 48v 600W zener diode.
I'd like to replace it with an original as the control board and connectors are all in place. I've read that the 300asc can just drop in?
I would appreciate any help to source a board either new or used.
I've seen them on Ali-express for $180 delivered but that's too expensive.

Thanks.

Can you give link to what you've found please?

I too think I'm in need of 1 module (or possibly 2)

The bass unit of each of my Martin Logan Summits uses 2x 200ASC, and one of the speakers instantly blows main fuses. I'm in the middle of diagnosing, but seeing as the mains is only connected to the 200ASCs, it's a good assumption that (at least) one of them is faulty. Just like you, as a first pass it's easier to replace with a fully compatible item rather than interpret alternative looms and wiring for alternative power amp modules.

Thanks

I had already emailed that seller on AliExpress and he tells me he has no stock.
I also found another at the same site who had to refund me because of no stock.
They seem to be advertising these boards without any stock available.

Good morning

Can you make a pic of your boards? i do not think that the 48V 600w is really burned because then the layer should be distroyed i guess.

how does your caps looking? normaly old caps for a SMPS get a hump at the top.....after years of using
