    Hi Pioneer freaks. Normally i don't lurk in these corners of the forum.. but! A good friend recently bought a nice Exclusive M-3 power amplifier. After a short test run on his JBL L212 loudspeakers we went to open it up to check out the insides. Just as i expected a few capacitors were bloated and some already spit their guts out. So i believe a recap is in order!
    But on my usual resource site i couldn't find the service manual for the M-3.
    I hope that one of you guys can help me out here!

    This looks like a great amp. The scheamtic (but not the servcie manual) is here: https://www.hifiengine.com/manual_library/pioneer/exclusive-m3.shtml

    By "some already spit their guts out" - ensure you arent confusing any factory glue (used to seat these caps on the PCB) with any actual ruptured caps. If it is the latter - you shouldnt be running the unit. Actual vented caps will usually vent from the top or bottom and leak an acrid smell in a unit. If they really have split open, you may also find pools of dried electrolyte on the bottom of the amp.

    Thx for your reply Slimecity!
    IT is a really nice amp! Hifiengine is my first choice when searching for a SM. But they didn't have the one for the M-3. That's why i tried my luck here. And appriciate the heads-up on the glue. I'm well familiar without that, i saw it a few times on multiple Yamaha amps. Some caps really did puke! We don't use it since we discovered the bad capacitors. Compiling a caps list as we speak.
