Hello all! I'm kind of late to the party, I've been lurking the past few days reading this fine thread. So far, I've only digested 175 pages, about half. Whew this is a long read! Got all of the parts together to do this build, scrounged an old finned heatpipe cpu cooler from the junk parts bin to put up top for the fets. Below is a blurry pic of the mock-up, hope to have it wired this weekend. Wish me luck! BTW as an intro, I love all things audio. My hobby is restoring 1920's - 1950's tube radios and 1960's - 1970's stereo receivers. Just did a Marantz 2275, at the moment I'm rebuilding a 1963 Sansui 1000.
