    Need Alternate SA-9500 BOM

    Hey guys, I was trying to order the SA-9500 BOM from mouser as I have 2 of them incoming (working on one currently, as well). Problem is, most of the Nichicon's on the list are out of stock with some not expected until Nov, Jan and Mar!! I do not want to wait that long to refurbish these...

    Pioneer SA-9500 : Troubleshooting Noise

    Hi, I bought the SA-9500 new in early 1977, but pretty sure it is a 76. I have never serviced it. It sat from about 1990 until last year (2020) when I brought it out to use with my phono system. So was used almost every day for 16 years. I opened up and did basic cleaning and once pots and...

    Hi, Wondering if anyone knows whether the SA-9500 Phono 2 stage, when Impedance dial set to 50 ohms and Level all the way up (0db) is going to be the same basic settings as the Phono 1 stage?

    Time to restore my system

    Hi, Well where do I start........ 40 years ago I started to buildup my HIFI system with the purchase of a second hand Pioneer SA-9500 amplifier and PL112 record deck. Adding Sansui SP-9100 speakers, that was the start line. Over the following year I added more pioneer components: CT-F900...

    Pioneer SA-9500 Mk1

    Last year I bought a Pioneer Sa-9500 for $350. When it works, it sounds pretty good and blows any modern amp I have used out of the water. It is experiencing the issue these amps seem to have (power protection grid failure), and I wanted to know if it was worth having it fixed or if I should...

    Pioneer sa-9500 hum?

    Hi I have a pioneer sa-9500 that has a horrible non DC related hum out of the speakers. When uncoupling the amp and preamp the amp seems fine but has a faint hum while the preamp is horrendously loud. Any ideas on where to start? I've been messing with this thing for a couple weeks but...

    Pioneer sa-9500 hum

    A while ago I picked up a pioneer sa-9500 amplifier that , according to the original owner, did not power on. After repairing a cold solder joint or two the amp powered up just fine but now it hums very loudly. First I figured the hum was a DC problem but there is absolutely no DC on the...
