am not sure if this one should be called a prototype or an experiment.
I bet Kevin Haskins of DIY cable didn't realize that he would
be represented twice in this event (sort of). Gary Dodd purchased
a couple of Hypex UDC-400 amp modules from Kevin months ago and
had them laying around. So he finally did something with them.
I know, Gary is a professional amplifier designer, but his effort
clearly showed what can be done with stock Hypex modules and a
good power supply.
had an old Adbomb (code for Adcom) chassis laying around that
was a perfect donor chassis.
the rear was typical Dodd Audio inputs and outputs from Cardas.
On the front panel is a power on/off switch and a stand-by or
thing was by far the heaviest of the event. Gary used what he
called a "real power supply". It had dual input transformers,
one for each channel of coarse. Then since it was fairly efficient,
he decided to add a balanced power transformer to reduce the noise
he ever does bring it to market as a product then he is thinking
that he will add a couple of high quality Hubble electrical outlets
to the back of it so that other front end components can run off
the balanced power supply too.
400W into 4 Ohms, 200@ into 8 Ohms.
