We did a couple small runs of these aluminum chassis and have a limited number to sell. We have both black and silver powdercoated. They are fully machined and CNC punched to specifications. You can use the layouts on the Amp Garage Forum Website to build many different variations of D-Style amps.
These chassis are well documented and many successful builds have been done with them over the years. We have D-style eyelet boards for sale as well, relay boards, and can provide headshells for these chassis as well.
