AndreG. Posted August 29, 2021 Share Posted August 29, 2021 I´ve been thinking for a while now. I would like to retire my old Pioneer SX 304 in our dining room. At the moment there are two Yamahas on Ebay that might be options: • AX 396 about 118$ • AX 570 about 83$ They will drive a pair of R15m plus sub and are more for ambient music than serious listening. Although, if i like what i hear, i might experiment and hook it up to my Heresies. Opinions from the forum? Quote Link to comment Share on other sites More sharing options...
Racer X Posted August 29, 2021 Share Posted August 29, 2021 Not sure why you need the forum's validation for a $100 amp, but you have my blessing. 1 1 2 Quote Link to comment Share on other sites More sharing options...
AndreG. Posted August 29, 2021 Author Share Posted August 29, 2021 Ofcourse i don´t need anybodys "blessing". I was more interested if anyone owns or has owned one of the two amps and can say something about them. 3 Quote Link to comment Share on other sites More sharing options...
geezin' Posted August 29, 2021 Share Posted August 29, 2021 While I've no specifics cannot recall hearing anything but praise for Yamaha's equipment. About $100? What's not to like? 2 Quote Link to comment Share on other sites More sharing options...
Pondoro Posted August 29, 2021 Share Posted August 29, 2021 I’m very happy with my new Yamaha and it is one of the few makes that is rarely criticized online. So if they look good and you can test them I’d say, “Grab one!” 1 Quote Link to comment Share on other sites More sharing options...

absolve2525 Posted August 29, 2021 Share Posted August 29, 2021 I have a Yamaha receiver from that era, stereo only and similar power to the 570. It sounds excellent. I wouldn't hesitate to try it. 2 Quote Link to comment Share on other sites More sharing options...

Islander Posted August 30, 2021 Share Posted August 30, 2021 What year would those amplifiers be from? Yamaha makes very good gear, but their engineers continue to improve it over time. When I replaced my 1977 CR-1020 with a 1998 RX-V392, even though the 392 was the entry level bottom-of-the-line model, the sound quality and clarity was greatly improved. Since then, I've upgraded again, and every time (RX-V392 -> RX-V750 -> RX-A2060) there was a noticeable improvement in the sound. If you're not in a hurry, I'd suggest that you continue to look, to see if some newer and better Yamaha amplifiers show up for sale, since newer units should sound better and be more reliable. Buying the least expensive unit that you can find is one way to go, but then you may find that you'd like to upgrade your system, meaning you have to go to the bother of selling the ~ $100 amp and then buying another, more expensive, one. Why not get a fairly good unit now or in the near future, when prices may be low? 4 Quote Link to comment Share on other sites More sharing options...
Bubo Posted August 30, 2021 Share Posted August 30, 2021 Lost count, I have 8-10 Yamahas and won't sell any of them Love them Try the 100wpc unit, might have a little more bass 3 Quote Link to comment Share on other sites More sharing options...
AndreG. Posted October 24, 2021 Author Share Posted October 24, 2021 These speaker relais in my Yamaha give me some trouble lately, i have to push the appropriate speaker select button a few times to make the left speaker work on the A channel and for the right one on the B channel. I already gave the buttons a spray of contact-cleaner. Do you think it might be feasible to drill a little hole in them to get some de-oxifier inside? 2 Quote Link to comment Share on other sites More sharing options...
Bubo Posted October 24, 2021 Share Posted October 24, 2021 Clean the contacts on the switch Replace the relay Clean the speaker connectors Ensure the speaker wires are secure in the connectors, powered off Inspect the bottom of the board for bad solder joints, shorts Next would be check the pre amp section or have a tech check it Then move on to the amp section Weak transistors will sometimes fade in out 2 1 Quote Link to comment Share on other sites More sharing options...
billybob Posted October 24, 2021 Share Posted October 24, 2021 That is abit where I am at with mine. There are in alot of some YouTube videos some that are either replacing the entire relay switch. To get at it properly to clean, some desolder the switch. The contacts in the relay is what they are cleaning. The top cover of the switch if can be removed easily enough, without damaging for access to the contacts. Problem is, there are resistors, etc., In close quarters around the switch, which can be damaged if attempting with out caution. So, yes, if can sell a small hole in top of switch, without plastic debris falling into the switch, further complicating contact operation in relay, would look closely and possibly be able to directly insert small plastic straw onto the contact portion. Cycle switch while light spray several times. And after all this to consider, whatever method used to clean, no guarantee it will fix or help problem. Measuring the voltage level operating the switch may well come into it. It gets more involved as well. Maybe bubo will say. 1 Quote Link to comment Share on other sites More sharing options...

Don't waste your time playing with a $12 switch Just replace it and see if the problem goes away Black box repair method Still do the rest of the inspection and cleaning touching up a few cracked or lose solder joints can work miracles 4 Quote Link to comment Share on other sites More sharing options...
billybob Posted October 24, 2021 Share Posted October 24, 2021 Glad you got around to saying that. Was going to. Replacement for mine is 5.98. Likely just to speak to a repair tech. just saw locally. My relay stopped clicking. Sorry for the slight Yammer I have in the morning. Just got a cup of coffee. Hope it will help. Good morning ... coffee.☕ 1 1 Quote Link to comment Share on other sites More sharing options...
