I posted a thread on this a few weeks ago but I now have all the details that I needed so here it goes. I have a SWR SM-900 (Pre-Fender Red Logo) amp that has been in a local authorized repair shop for 3 months now. After the shop making numerous calls to SWR, replacing various parts, and having all the shop techs look at my amp they have come to a dead end and are not able to solve the problem or repair my amp. So here are my options. 1.The repair shop talked to the old head tech from SWR and he thinks he can fix it but it would cost me anywhere from $350 - $550 plus shipping to have this guy fix my amp depending on what needs to be replaced. 2. I can pickup my amp at the repair shop for $150 (Labor cost) with nothing fixed. 3. I can give the amp to the shop and pay nothing so they can use the amp for some spare parts. Keep in mind that the amp is out of warranty and this is the second repair shop that I have tried. I would like to know what everybody here would do? Should I pay the money for repair or just go get a new amp. I am highly looking into a Genz Benz GBE750, SWR 750X, or Ampeg.
