Description
Up for sale is a very nice Yamaha C-2 slimline Preamplifier. These were made in the late 1970s and were the very popular companion to the B-2. Still has the original owners manual with it.Deceptively small, concealing high-end layout, circuits and parts.Yamaha ultra low-noise matched FET pairs for the EQ stage, precision four-gang volume control, polystyrol and metal film caps, low-impedance outputs, deported selector shafts and double shielded phono stage.The all-metal and all-aluminium chassis is in fact four in one, with each of the three boards and transformer being entirely separated of the others.As per Yamahas habit between 1976 and 1982 for its high-end components, there are no visible screws anywhere revealing the attachment points.The phono stage allows connection of three turntables/tonearms, phono 1 & 2 being MM and identical, phono 3 being MC for low-output cartridges.The EQ amp is made of three stages : cascode-bootstrap current mirror differential amp (1st), Darlington connected constant-current load common-emitter amp (2nd) and fully complementary parallel push-pull Class A (output).Preamplifier came out of a working system and I ran it yesterday for about 2 hours with my Krell KAV-3250 and it sounds great. Inputs etc... all seem to be working as they should. Due to the age, my guess is it probably needs a tweek or two if you want to return it to factory spec. Cosmetically a few tiny surface scratches are on the top and along a few inches on the left edge but you dont see them if its sitting in a system. I would say B+/A- for cosmetics especially since its 45 years old. Lots of detailed pictures.
