it looks like that but is a 4ch amp.

Does it look exactly like that from the top?

Does the board have anything printed on it that would indicate the model?

timwebb · 12th November 2011, 09:29 PM

yes it looks the same. there is no name on the board. this is my board.

If you remove the outputs from the blown channel, do the relays engage?
