    Pioneer SX-1980 Exterior Restoration

    A while back I finally bit the bullet and bought a Pioneer SX-1980 off ePray for too much money. It was sold as not working--for parts but "powers on". Which was fine with me. It showed up a bit later in far worse shape than the epray pictures. It was packed in a box the same size as the...

    reputable service in my area sx-1980

    Hello fellow members, I own a "Monster" SX-1980. My FM tuner is completely useless at the moment. It was functioning perfectly up until a few years ago. Since then I purchased an Onkyo Tuner as a substitute "fix". I'm ready to have the Monster repaired. I live in Central North Carolina...

    SX-1980 PA3004 Shot?

    I have fully recapped this unit and installed a Delta9 Electronics populated power supply. All is good except when powering the unit on. I am seeing power meters jump up to the 0.1 watt area once the protection relay clicks and then the meters settle back to zero. I also notice the protect relay...

    A $9200 receiver? Really?

    Maybe it's me, but I have a hard time believing that this re,ceiver is going to sell for this price. Plus a $200 shipping cost on top of it? I've seen these posted for $3k and thought that was outrageous! I sold a nice 8" feild telescope on eBay and I shipped it from AZ to WV and it cost me...

    -- Hi. I have a Pioneer SX-1980 with a low hum after a power failure. I was told to change the four 22,000/100V filter capacitors. I have never change anything before since 1990. When I opened it I found a loose black cable. See pictures. Can it be making the hum or do i need to change the...

    Battle of the Titans: Pioneer SX-1980 vs Sansui G-22000

    I decided to compare my two monsters head to head and see which one would come out on top. I love both of them, definitely the two biggest pieces of audio I own. Both have been meticulously restored and fully recapped. You can see the restorations threads below: SX-1980...

    Help with SX-1980 New AWR-154 Board pleeeeze

    Hi AK folks. Long time lurker, first time caller! I'm normally a vintage tube audio guy but couldn't resist a 30 buck SX-1980 at a garage sale maybe 15 years ago. It has the typical toasty power supply board with much of the foil hacked up by a PO. Back then, I couldn't find a used board to...

    SX-1980 Quartz Lock Issues

    I recently acquired a 1980 that was fully cleaned, power supply rebuilt and the tuner supposedly aligned. The unit works and sounds great, however the quartz lock will not stay locked. Usually, right when I power the unit on, the quartz lock works as it should. After about 30 min to 1 hr give or...

    SX-3900 vs SX-1980

    Everyone is familiar with the Pioneer SX-1980 beastly stereo receiver. I get what’s special about it to a very limited extend: the insane 270 wpc, the 3 speaker channels, the heft and size, and the beauty of all analog. However, why doesn’t it’s successor, the SX-3900 get nearly as much love (I...

    Always-on Pioneer SX-1980

    First thread! I picked up an SX-1980 recently. I've been enjoying it as well as my wife (neighbors get routine Josh Grobin concerts when I'm at work) for a few months now. A couple of weeks ago my wife facetimes me when I'm abroad on business and shows me turning on and off the power switch but...

    SX-1980 is in protection when first switched on

    A couple of years ago I picked up a SX-1980 in rather rough shape. To be brief the Power Supply Board AWR-154 was almost unrepairable for a rookie like me so it was placed in the back closet and left for another day. Then txturbo came along with his new board so I took the easy way out and...

    It's Halloween - SX-1980 monster in my house! Thoughts welcome!

    Hi guys, after endless searches and missed opportunities I was quick (and lucky) enough to score an SX-1980 on Ebay Classifieds. Called the seller five minutes after he posted the add, fixed a reasonable (but no bargain) price and agreed to pick it up on the other end of the country... 900 miles...
