    I don't think there is much of anything that cannot be repaired on a 980, except maybe a unique switch. All parts available still on the boards I believe. If you really like it an want it better, and more reliable, I'd do more than just repair whilst in the shop.

    Agreed, if I were in his shoes, I'd get that 980 singing, regardless of buying something new too!

    The ¨doctor¨ just called from the hospital saying he can't find any fault with it, that MAYBE it's just some dirty contact, that he'll get back to me with what he finds; so far everything is within spec inside. I told him to revamp everything, cost no object relatively speaking, because anything will be cheaper than buying a modern one, esp new.

    I'd thought of the Rotel 1570; some guy sells one for U$ 1500 on the local Ebay, but has no proof of purchase, yet he claims he bought it new and used it for only 3 year (this model was made from 2013 and it's discontinued now) so for all I know it might be even stolen. Guy has box and manual and cosmetically it's spotless. Any thoughts on this amp ?

    That's frustrating. Happened to me with my NAD amp over the period of almost a year with three different repair shops. The problem came back and that was it for my decision to move on (to an even older Adcom amp which has remained bulletproof).

    The problem used to appear randomly but once in a while; I waited till it showed up every time I used it, and now no ¨no fault¨ . My biggest fear. Maybe it was just a stubbborn contact inside that got jolted with the car trip to the store ? Adcom trumps NAD in my book so congrats man !

    I actually thought the NAD 216 was a great sounding amp. It was a mosfet design and had a warm, big bottom end I really liked. The Adcom 535 is a back up now to my newer Parasound 275v2. Your Pioneer is gorgeous. Wouldn't blame you for keeping it going!

    Repair kits are available on ebay. This one is just a sample I pulled.

    Pioneer SX-980 rebuild restoration recap service kit fix repair capacitor | eBay

    My $.02; I have a minty SX-1010. Had it re-capped and serviced last year. $460 including mesmerizing new blue LED's. Good as new. Your 980 is a 80wpc. Probably all hand wired. It also has that desirable mono switch if you're into older vinyl.

    Could be something like an intermittent solder joint. I’d still have it repaired. You’re obviously not a gear flipper and like it. Switching to something else could be a mixed bag unless you can listen on your speakers before you fully commit.

    Side note. I still have an Adcom GFA-535 mk2 that I use in my lab and as a back up amp. The 535 is the best sounding Adcom from that era, even though the 555 was the popular one. I’m still contemplating rebuilding the power supply with a new board from hoppesbrain.com, but I’m never short of projects. Maybe this Winter…..

    My 535L got a little noisy in the right channel. All I did was replace the internal fuses and Deoxit everything inside and it improved. Haven't had it hooked up for awhile but tempted. Afraid it's going to sound better than my new Parasound! :yikes:

    check out Hoppesbrain.com. I can’t remember if it was that one or the original 535 that could be improved with some better grounding. But I remember something about noise in one channel being mentioned.

    Absolutely a gear keeper. I fall in love with something and never want to change it.


    That's the idea, but down here they only repair what's broken really. Every tech I've asked for a complete recap has turned me down.

    My fear exactly. I'd like to be buried with it if possible, which, at 60, is maybe not too much to ask for:laugh:

    Your Pioneer SX-980 is a gem. They regularly sell for over $1,000. Besides the emotional attachment, it's just an excellent piece of kit that can't be replaced under $1k, so worth the effort to fix.

    I know about emotional side: we inherited my wife's dad's Yamaha receiver. Unfortunately it didn't work for long. developed a hum and other similar symptoms to yours. But ours was a low-end Yamaha that wasn't worth $200 if in excellent condition, so we made a Goodwill donation of it. The good thing was it re-kindled our interest in hi-fi and we've since grown our system to some quite nice modern pieces and enjoy collecting vintage jazz vinyl, all because of her dad's receiver.

    1000 bucks here too; don't think anything under a Yamaha AS-1000 can replace it. Hope I'm wrong though.

    The receiver is beyond time to rebuild.

    Meaning too late ? Rebuild I will if the tech says it's necessary and feels up to the task. But they just don't rebuild here; can't force them. No easy access to parts like in the USA.

    Hand truck, moving blanket and bungee cords should solve the moving it from place to place problem. Top of the rack to the hand truck no problem for two people. Good luck. :)

    Strong big friend with a van solved my problem already, but thanx for the idea anyway.

    I do own a 60wpc Technics SU-V5 in perfect running order. It might take the Pioneer's place in case it turned out to be a lost cause. Sounds grreat but it's inferior to the Pioneer. I use it to watch concert DVDs on a secondary system, which I'd unify with my primary; worst case scenario that is.

    Definitely not too late nor lost cause to refurb or fix the 980.

    Yes, hard to get a tech that will do as you ask, strange how they are that way, but it is common. Likely your tech will be that way as well. If he is just ask if he'd fix the immediate problem, clean all switches/contacts, then replace all caps in the power supply. Probably no more the 8 capacitors there. This is something you should likely hear (as better) and in the realm of something your tech might do in lieu of an entire recap.

    I believe if you advertised for your needs someone at AK would do a restoration for you.

    Thanx, but what's AK ? Missouri ? I'm in Buenos Aires-Argentina, hence, the problem.
