Time to build another amp. I’ve gone round and round on what to build and after a few false starts, I finally settled on this odd mixture.... a Carmen Ghia front end and a 6AQ5 power section, long tail pair phase inverter and cathode biased. Chassis starts as a section of 2” x 4”, 1/8” wall rectangular aluminum tubing. End caps are made from solid aluminum and are machined to fit into the ends of the tubing. The ends are installed and then the tubing is machined top, bottom, front, and rear. Then I fill in the engraving with black paint, let it dry, then sand the whole thing with a random orbital sander and 220 grit paper. Clean it all off and give it a coat of satin clear. While the chassis cures, drill the board and install the turrets. ....and then solder on a bunch of passive electronic components. It’s a tight fit! This build is actually a bit of experiment in packing 10 pounds of stuff into a 7 pound bag. If it works out, I hope to do another build with a similar circuit packed into half of the total space.
