Sansui au-217 au-317 Amplifier Common Faults. Diodes, Transistors, Resistors. VD1212, MV-12, 2SA726

A few common faults that I fix hoping to mend my Sansui au217 amplifier
that also applies to the au317 as well

Took mine in for repair a few years back the fuse resistors were replaced and one transistor on each channel. So I would think very much the same as what you have done here. Its a great amp and for the £100 repair bill it was worth every penny. Great Video. *edit* Just found recipt was £80 labour £8 parts plus vat £105.60

Thanks for the comment and the price info is interesting. Always wondered what they charge these days for small repairs.

Hope your eye gets better. I don't have any advice, maybe a warm compress like a flannel in boiled water in a bowl, let it cool a bit till its just hot water and put flannel in, rinse it out and hold it over your eyelid for a few mins. Maybe it might help move out whatever is irritating. Or could you try one of those "eye bath" things, plastic thing you put fluid in and hold to your eye? Anyways, regarding amps that have been serviced etc, that Hitachi receiver I bought, the guy said it had been serviced recently but I don't know what, he didn't say. I wouldn't say it sounds any better than any other amp I bought that is vintage. Also bought a Technics amp (SU C04) 2 years ago and he said he had replaced 90% of the caps. Sounded nice but it had one channel quieter than the other one.

Thanks Alex, Ile give anything ago. I see so many on ebay saying had a recent service then all of a sudden up for sale, seems a little funny to me but who knows. I would like to see some pictures on inside that migh comfirm this. Same a tape decks, new belts fitted, I wonder how many actually are. I bough a Sony deck about 5 or 6 years ago. Seller said it was service , new parts, cleaned , new belts etc and sounded good as new. I got it and it sounded awful sent it straight back.

@MichaelYates yeah had a few like that "works great, sounds great". Then when you check out the seller, you see they copy and paste that into all of their items they have for sale, audio gear anyways. I actually bought an 80s boombox earlier this year and when playing tapes, volume was low had to turn up to 3/4 volume just to hear it. Radio on other hand worked fine. So I contacted the seller and told him and asked for his help and he told me "try a pre-recorded cassette rather than a blank". What?? I told him I made the recordings on my blank cassettes myself from CD and they all worked and sounded fine. Anyways, he dug in and didn't want me to return it, made me an offer etc. I took a video of the unit just to prove I wasn't lying. When he got the unit back he said it was working fine, there was no issue. So I said "you can see the video I took if you like to prove it". Never heard from him again.

@@AlexMitchell-sj4sb That was a pretty cheaky comment he made there with try a pre recorded rather than a blank. I also see AI is being used for the description of item as a lot say pretty much the same no matter what make or model . Saying how the item "is a high-quality device designed to enhance your music listening experience" that same saying is on so many for sale these days. lol might be with some if they work correctly.

[@AlexMitchell-sj4sb]

@MichaelYates have noticed that too Mike, description written by what looks like AI, no actual relevance or thought gone into selling the item. Very copy and paste mentality with little thought or imagination used. I always give abit of insight into the item, list any faults even if minor and sometimes explain it's my item and why I am selling it on.
