    Infinity sub amp and Onkyo 2 ch reciever

    Hey all, looking for some advice

    First i have an Infinity sub amp from a ps10 that turns on, makes buzzing noise louder and louder till it shuts itself off. Noticed someone on ebay fixes them so it must be quite common.

    Anyone have any idea on what goes out on these?

    2nd i got a 2 ch onkyo tx8050 reciever that has never had any speakers hooked up, it was used as a controller for an old bose 5.1 amp they sold way back in the day, so only thing used was the 2ch preouts fed from the optical from tv. It turns on with half dim display and then protects or shuts down after about 5 seconds.

    Looking for any insight. Im not new to fixing or soldering. I soldered some new parts on a $2500 motherboard out of my Roland versa cam and also a bunch of not so touchy parts as well.

    Ok sweet, i just found the ps12 amp thread which is the same amp as i have. I dont have the obvious cap burning areas though, but part of the board is brown.
