I picked up this head used a few years ago for a song ($300 CDN.The retailer thought it was a preamp only). I don't use it anymore because I needed more power, and it sounds sort of loose and mushy to me. The DI out sounds great though, so there may be a problem with the power section. Anyway, does anyone have any info about this, such as where I could get a service manual? I ask because I would like to get it fixed and either sell it, or get a small cabinet and use it for home practice/recording. Spec wise the closest thing that Trace made (before they went out of business) would have been the RAH 300SMX. Thanks.
