au-x1

Dear All I have had the good fortune to find an AU-X1 here in Denmark, pretty beaten electrically, but with the help of a friendly tech (and amongst other components, a new set of output transistors from Kale), its been brought back to life what regards the line and power section, and it plays...

hi all, Just picked up a sansui x1 a month ago, and although the phono inputs had no sound coming through, i was able to use the Aux input for some good listen on a set of jbl's 4312a. Then the other day, turned it on, played some audio for 30 seconds and it cut the sound and went into...

This posting is for the benefit of several AKers who recently acquired my F-2772 for their respective AU-X1's. I thought a single reference point would be the easiest way to answer questions and to share ideas. Instructions for installing the new 2772 board into your X1. PARTS LIST Needed to...

Original Mk2 Phono Mother Board - with replacement relays Side view. New board fully rebuilt. Old board - Empty! There are just 2 (carbon film) resistors on this board, a 33Ω and a 5.6Ω - the 5.6Ω had drifted to 7.4Ω so it was replaced, along with the 33Ω for completeness. The new board...

I fired up (literally) my AU-X1 yesterday because I was feeling nostalgic. One channel was silent. So I went around to the back and found that on of the RCA connectors was loose. When I plugged it in I heard a distressing "sizzle" from deep inside the amplifier. The power/protection light...

Quite a surprise to see one of these presumably very rare tuners come up for sale (on eBay UK with a starting price of £1500). It's unfortunate - for both the seller and any potential buyer - that FM broadcasts from the UK are in danger of ceasing once digital reception has reached a certain...

Procedures and other data - start Procedures and other data - end The service manual (SM) for the Sansui AU-X11 has eluded my and everyone's (even boffins here in Japan) best efforts to locate.So I think that it is past time that an information collection point be created to accumulate any and...

In the past here on AK I've asked about possible substitutions for this Hitachi 24V reed relay . Although there were a couple of what I am sure were good suggestions, there was nothing easily get-able for me until I saw this today. Well it seem some good chap here in Japan who goes by the...

Happy New Year everyone!! I am seeking suggestions as to who provides quality PCB fabrication services for the humble hobbyist. Please see my thread about it here http://audiokarma.org/forums/index.php?threads/pcb-fabricator-opinion-and-suggestion-request.750469/ Its for a good cause. The...

This vid is rather new, and rather short, but comprehensive for it's brevity. :bowdown::bowdown:Mr. Yoshiro Yamamoto here really knows his stuff.:bowdown::bowdown: (His X11 had some huge problems as you will see.) In my comment, besides my praise, I hit him up for the elusive X11 service...

After an initial listening test, which I was very pleased with, further checks have revealed some problems with the amplifier. Right channel, cannot adjust bias, DC offset OK. Left channel, could initially set bias, but after a slip with a probe, (comparing L&R), and 68 volts appearing on the...

Well, I finally have one, it's a 100V version, made in August of 1980, right near the end of production I think. External cosmetic condition is at least 9½ /10, internal condition a little dusty, and looking quite untouched, it also has as set of original output transistors. :thumbsup: Overall...
