Anybody use a Dynaco QD-1 Quadaptor?
I have a Dynaco QD-1 Quadaptor I built as kit costing $18 in the early 70's. This is a passive system that adds two more rear channels to two stereo channels. It is hooked up to the two stereo speaker outputs of the amp and has four outputs for four speakers. The circuit consists of a rear speaker rheostat and two resistors and switch to allow two channel operation or four channel operation. So I was into surround sound in 1970!!
It seams to add depth to some music with good stereo separation.
Anybody still use a Dynaco Quadaptor besides me?
