In this this video, I start the preliminary evaluation of a Yamaha CX-1000U Natural Sound preamp. As such, I discuss my approach / mindset concerning restoration from the perspective of preserving the original design in regard to sonic performance / characteristics.
In this video I cover some signal tracing tips on this Jolida JD1000RC vacuum tube stereo amplifier. This is a unit I worked on in the past, however, all appears well with this amp as I evaluate a channel issue within the customer's system and not specifically this amp alone. All of the components that make up his entire system where brought in for diagnosis. Therefore, we'll see what proves to be the problem, stay tuned !
This is one of those lengthier videos covering the troubleshooting and repair of a Garrard 3500 turntable, which is part of a Sony HP-485 "combo unit". The turntable had no auto function and a dead left channel issue.
