Over on Audioasylum there is thread about the Carver Crimson 275. The amp is rated as 75 watts/channel. When someone pulled the covers off the output transformers, they found an Edcor transformer rated at 15 watts. When tested by Audiosciencereview, the amp only produced 17 watts a channel with 1% distortion, and the fuse blew at 29 watts.
If nothing else, the company's published specs are very misleading under normal set of standards.
