    Sansui AU-317 caps

    Hi folks!!! I recently bought a Sansui AU-317 and after a quick look under the cover i noticed some capacitors, 6, have been replaced by axial caps brand ITT 100v 330mF. If i'm not wrong original ones on this model were ELNA 50v 470mF. Can that somehow wrong recap cause any problem? The amp, for...

    Sansui AU-317 Protection Circuit / RED LED issue

    Hi All I bought a 317 on eBay. The most filthy dirty unit Ive ever seen but I can see it will scrub up nice. Both main fuses on the PCB had blown etc so I just got stuck in on the restore and clean up. Cut along story short I replaced the standard components that normally needs changing on...

    Sansui AU-317 turns on but no sound

    A few weeks ago I bought this AU-317 MK 1off eBay however when it arrived there was no sound coming out of it. Went back and forth with the seller and ended up keeping it at a significant discount. I've checked all of the audio inputs (AUX and Tuner) and channel outputs with no success of...

    Differences between AU-307 and AU-317?

    Greetings knowledgeable and enthusiastic Sansuiphiles! After reading all the enthusiastic discussion and restorations of the AU-n17 series of integrated amplifiers, I'm interested in acquiring an AU-317 as the next logical (to me, anyway) progression from my AU-4900 and AU-555A in my...

    AU-317 left channel static

    Sorry if this is a repeat post, I tried searching but couldn’t find the answer... I just replaced the fuse resistors with metal film resistors on my 317. Huge improvement, definitely needed to happen. Right channel now sounds great. Left channel has a crazy level of static and lower volume than...

    317 for repair...good deal?

    I'm looking for a nice vintage amp, and I have the opportunity of buying a Sansui AU-317 for 60€ (around $68). The amp is apparently not working (no sound coming out, but it does turn on). Without knowing much else, is it worth buying in your opinion? I don't know much about the brand besides it...

    Another TO-3 ➡ TO-3P output conversion

    Another TO-3 ➡ TO-3P conversion I received this Sansui 317-II, which has the right channel dead. The owner said he uses Alesis passive monitors at 4 ohms. This version accepts minimum 8 ohms or higher. Also, the unit was wired for old 220V operation and had 2 blown 8A 60V (!!) fuses. Checked...

    Any NoVA AK'ers willing to go through my AU-317?

    Hey everyone. I recently picked up an AU-317 from Bartertown (thank you, vinylndunks!) that I'd like someone to go through, clean up, and check to ensure everything is up to spec. I want this to be the last amp I buy for the next 10 years, so just like purchasing a used car, I want someone to...

    AU-317 - bias problem causing blown outputs?

    Hi all I'm repairing a 317 that went pair shaped a few weeks ago. I'm learning as I go but I've got into new territory and I'd appreciate a little help narrowing the search for what might be the problem. I replaced output transistors TR17 and TR19 and driver transistor TR15. It now seems to...
