Mackie SWA 1501 SUB AMPLIFIER - A&J
The Mackie SWA 1501 Sub Amplifier is a quite complex circuit involving a switching PSU a class H Bi Polar output stage combined with a FET output stage,( the Americans refer to class H as class G - see literature on this amplifier) it is overly complex in my opinion, these type of amplifiers are not necessarily the most reliable, or the best sound quality, but they are a cheap route to making a hh power amplifier, using conventional circuit architecture would be a lot more expensive to produce, after all what fun it is making something more complex than it actually needs to be, the hy paid Mackie desn department have to justify their wages !

You can see below after testing numerous components we found loads of things blown, this is to be expected on a desn like this, catastrophic failure of multiple devices throughout the board, these were removed and the PCB was given a good clean to get the carbon debris off.
