I have another custom digital amp built for a shootout a few years ago at Danny's. This thing is built into and old Adcom GFA-555 chassis. The rear plate has been remade out of 3/8" thick aluminum for rigidity. It is based on the Hypex UCD-400 modules and they are stock!
The power supply rails are plus, minus 60 volts and that is coming from an 800 VA transformer, dual windings feeding 2 full wave rectifiers in a pi configuration. As you see in the pics I have included the bottom toroid in the center is the main transformer. There is a 18mh 16Amp toroid choke on each
side of the main transformer,1 for each rail. There are 4 6800uf/80v nichicon cans on each side of the chokes for a total of 54,400uf per rail!
You'll notice another large toroid on top of the main toroid, that's for the full balanced power supply that is built into this amp!
, you can notice the input filter on the IEC connector into the fully balanced toroid. Thats how this amp creates the sonics that it does. It makes 200 watts at 8 ohms and 400 watts at 4 ohms continuous, actually it measures more than that! It is incredibly quiet!
It is in perfect working order and ready to go.
I am asking $800 for it and I believe that's a deal!
BTW the amp won the shootout!
