Your having audio issues? Maybe the troubleshooting flowchart is the solution.

the bias was checked by a repair tech he checked all the trainsistors everything filter caps everything was ok...

cerwin vega power amp A 2200

I checked the bais and it is 37.5 all are in the same range its not the bais that is making the amp get hot on the right side and i mean hot so you can cook on it but the left side is ice cold even after 7 hour of play time. The only way to keep it from burning up is to place a small 3 speed house fan on it to keep it cool can some one help me correct this every circuit was checked thoroughly and everything checked out good 2 technicians check the amp and could not find the problem they are a dumb founded on why this is happening noting checks out bad or shorted.

I think the vintage cerwin vega power amps have sick power and sounds outstanding i have a cv 900 new i got it for christmas in a sealed box form cerwin vega store in california i compared both amplifiers and found the a2200 out performed the cv900 and had no distortion down and power was rich on the a2200 compared to a distorted low powered sound coming from the cv 900 when the volume is turned up. Also the cv 900 is made in china but a2200 is made in united states both are rated the same watts per channel but the cv 900 is garbage when compared to the vintage cerwin vega amps made in the USA.
 
Hi David,

I started this thread quite some time ago. It's intent was to show a flowchart providing a logical approach to troubleshooting a system problem but not a amp issue like your experiencing.

Because of this and the thread title/forum, the people that may be able to help you out and provide some direction more than likely are not even reading this. You may want to start a new thread in the Solid State forum so you can ask the question directly.

You'll probably get more traction over there :thmbsp:

Full size trouble shooting picture

I found a clean full size version of the trouble shooting picture. If someone would replace the original with this one, that'd be great:

Thanks!

As a newbie and a novice, I am going to need plenty of this kind of thing!

I connected my turntable to 2 technics amps last night and run a set of speakers off each amp and although it worked, the speakers were buzzing?..

There are a lot of questions that come up that could easily be solved with this chart. :thmbsp:
 
This chart says that if a power amp hums or hisses when nothing is connected to its input, the amp is broken, which is often going to be wrong.
 
Hello friends. I joined the site to seek answers to a problem I am having with my SONY STR-GX59ES. Also this is my first post so not even sure Im in the right thread to ask this Q. I want to find the problem myself since I'm kind of obsessive about "fixing" stuff myself. (note; I'm not an electronics/audiophile type person but I have tech skills). Q: The red "P" light comes on soon after power on. I know this is a "Protect" function caused either by a short or speaker impedance set wrong. All sound disappears and when it used to remain on for a while for longer periods (has gotten worse lately) It seemed to happen on volume up. Since I know its not "Impedance" can anyone point me towards what might be causing this "Protect" function to activate????
