The SPA300 kit is "smallest" of the Stereo Power Amplifier kits. It produces 2 x 100W at 8Ω and 2 x 160W at
4Ω. It contains a set of Ground Sound modules and enables the customer
to easily build a high performance amplifier. There is a bit of wiring, but pretty easy to do and all the nessacary
wires are included. The wires has to be soldered as we rely mostly on soldered joints - which will perform for a
very long time. The AmpC modules makes the amplifier smooth running at power on and off. The Transformer is
custom-made and has sufficient power for two PA1CC modules. The PSU4DB is the "battery" of the amplifier - it has dual
bridge rectifiers to lower the noise of the power ground and giving better conditions for the transformer. The PA1CC amplifier
modules has very good sonic qualities, which several of our customers has discovered. Our amplifier modules are
Class AB, but the bias current is low and at normal operation level they produce comparable heat as a Class D.
For this reason you don't have to build the amplifier around a huge heat sink...
