General Description

'''Technical Data'''

The RA100 is the simplest - but also by far the smallest - amplifier from the 1981 series, if you don't count the midi components. This was possible by packing the power amp part into a hybrid IC and using a toroid core transformer. Of course, a hybrid IC is nothing a high-end Hifi fan would want to see in an amp...
