    Dual 1219 Pop diagnosis and switch block internals

    I'm restoring a Dual 1219 and am addressing the "Pop" on motor start / stop. I've cleaned the visible contacts with DeOxit and replaced the snubber capacitor with a new .1mF cap, but still have the pops. Did a crocus cloth contact cleaning - no change. Also cleaned the mute contacts similarly...

    Repair Note: Pioneer SA-9100 Power-off Pop AWM-025C Protection Board

    Most SA-9100 schematics (all that I could find, anyway) show the AWM-025A board, mine has an AMW-025C with a resistor (R29) that doesn't appear on the AWM-025A board.The person who worked on this before me replaced R29, a 47k resistor per the AMW-062 schematic, with a 2.2k resistor. The result...

    SA-7800 occasional pop - advice needed

    Hi, after two years of daily operation with no issues at all, my SA-7800 started having occasionally "pop" in L channel. Reading the advices in AK I thought it could be the wiggly solder joints, so I inspected the board and have not found any. The only issue I did find is DC on the L ouput of...

    G-8000 Pop when relay closes

    Trying to figure this one out, when my protection relay closes, especially if the unit was turned off, left for a minute or so, and then turned on I get a pop of DC out of both my left and right speakers. Measuring the DC shows roughly 100-200mv when the relay closes, quickly dropping to 0. If I...

    2275 pops when powering on, and off

    This Marantz 2275 pops when powering on, and less so when powering off. Not the 'thump' of a 1060 powering up. But a noticeable and measurable pop, in both channels. The pops are varying each time, peaking between .5 volt up to 3 volts. When the main amps and relay are in circuit, the pop...
