    Kenwood 600 Phono Preamp Need CLEAR Schematic

    I'm seeking a LEGIBLE schematic of the phono section for a Kenwood 600. There is a problem with the right channel frequency response that a recap didn't fix. The poor resolution scan I have may not even be the right drawing as designations are different than the PCB screen shows.

    Help with Pioneer phono input

    Hello everyone. I have an old Pioneer amplifier SA 710. It has always worked very well, but for this morning the Riaa channel (left channel), emits almost exclusively static noise and Crackles. All other inputs (tuner, tape 1 and 2, aux) work very well. The static noise and the crackles increase...

    The "Members Only" Riaa Tube preamp. Gets a walnut cabinet)

    Preamps, a controversial subject, where does a person start? Well suffice to say I'm not convinced that I own the best, and i'm not convinced I ever will. After several experiences building and modifying preamp stages I feel like I have a grasp on what sounds good and what I like. Please bear...

    Turntable + Phono Stage + Active Monitors - Guidance Appreciated

    Hi I have a pair of Genelec M040 in my home studio. They are great monitors, but also quite musical for listening to FLAC music from my computer. Now, I'd like to try the monitors for listening to some vinyl. Since the Genelecs have no other gain control than a switch (high 0 dB, low -10 dB...

    Le Pacific J-FET phono preamplifier

    Hello guys!! Long time ago I decided o try the schematics of the Le Pacific preamplifier. If I try to power the entire bloc from a DC source the hum is higher, so I power it from 3 x 9V battery but they don't last so much. I also placed a 220uF/50V capacitor between + and - for reducing a...

    VINTAGE PHONO STAGE - RIAA

    Attached is a photo of two phono stages from early solid state integrated amplifiers. Without revealing the brand and model (and the assumptions of 'house sound') do the schematics allude to a particular tonality?
