Thanks, Waleed. Peavey makes some pretty solid amps, and are well known in the US for solid and long lasting performance. In the year I worked at Music Tech, we only had one Peavey come in for repairs and it was pretty far gone, when they go, they really go! Just one thing I wanted to mention, you note that you gave a good discount to the owner. I am not the one to tell you how to run your business, but I am somewhat concerned with the value that electronic repair techs are given. Here in the US there are not many techs, people just don't want to pay a fair price to get something repaired, and many tech make their income by fixing abandoned and thrift shop electronics which they then sell on ebay. Some others have found a niche for high value electronics that the owners are willing to pay a fair price to fix. I just worry that we E-techs just under-value our work to the degree that many people think we should work for free, at least that is the impression I get from many customers...

Dear Mr. Waleed
Thanks you for such a nice sharing in repairing history.Actually, this type of power Audio Amplifiers do provide better output impedence. Any how thanks you . Also, In pakistan usually, many peoples do use these type of Amlifiers because of Low in Cost and manufactured locally with 2N3055 Transistor.

Thanks you Again for your Experiences Sharing:
