Re: Repairing Alesis M1 Active mk2 Monitor Speakers
Take note that the Driver IC can be powered from a 15-19V bench supply. Current limit will be a good idea. This is just to troubleshoot and see that the IC oscillates. -

Re: Repairing Alesis M1 Active mk2 Monitor Speakers
Would be really cool if someone could come up with a step by step repair manual with all the tests and common faults to get these guys working again.
I have two to repair, and its proving really difficult.Leave a comment:

Power Amplifier Safety Modifications
I have a Large power amplifier that needs repairing for a client of mine.
It's a no-name brand stereo power amplifier and uses TO-3 lateral mosfets.
It has a large 500VA toroidal power transformer as well as a smaller 60VA toroidal transformer for the relay speaker protect circuits.
The builder didn't add any fusing except for a large 20A trip-switch wich doubles as the power-on switch too. I'm afraid the switch is too big in my opinion and will not trip during a fault situation. Removing it is not an option. Too much metal work.
Amp at least has a soft start circuit... -

Re: What op amps in side the RME firefaces models?
Not a fan of opamp rolling. If you want to better it, rather look at the power supply, filtering, heat management etc.Leave a comment:

Re: Help for mixing console BEHRINGER UB2442FX-pro
Clean ALL switches (push buttons) for starters. Most of the dead channels will come back to life. You'll have to do this anyway. Then you can check the rest of the mixer like the sliders, opamps etc.Leave a comment:

Esd bench mat. How much coverage
Hi.
I have just finished building a new workbench. The top measuring 2000mm x 900mm.
I would like to purchase some ESD rubber matting for the work top. My question is, how much covering will be enough? These mats are expensive here in S. Africa. Is it a good thing to cover the whole top, or more practical to do only a section??
