I have for sale a very basic DIY passive preamp, with 4 RCA inputs and 1 RCA output. The front has of the unit has a volume control and a selector switch. The case is aluminum. The unit uses a 23 stepped 10K ladder attenuator, suitable for chip amps and solid state power amps. This is an inexpensive way to add multiple inputs to a single input chip amp or solid state amp. It is certainly not the last word in passive preamps, but suited me fine while I was waiting for my permanent preamp to arrive. Email me at meicheng101@sbcglobal.net and I can send you pics. $105 shipped in continental U.S.
