Newby with 2 sick receivers; help! audiokarma home audio stereo discussion forums gas city indiana restaurants

###############

Hi everyone. My name’s Rich and I’m a gearhead who’s almost completely ignorant where electronics are electricity units calculator in pakistan concerned. I was surfing the Web looking for advice and info on a Sansui receiver I just bought, and came across the AudioKarma Exclusively Sansui forum. You guys really seem to know what you’re talking about, to the extent that much of the discussions might as well be in Greek! Now if they were in Italian . . . I’d still be lost. :sigh: (Besides, most Italian tech-talk is in English).

Both my sick receivers are Sansuis. I’ve been wanting to record my LPs onto CDs and my old 9090DB isn’t up to the task. So yesterday at a yard sale I acquired a nice looking Sansui S-X1130 receiver, serial number 605104523 (I believe Morden2004 is collecting these for a database?). It was said to be in working order, but when I took it home and connected it up, the Protection light gasco abu dhabi location remained on and nothing worked. I took off the top and found an obvious smoky area :tears: on the inside left front, above some sinked transistors on the same small board as a pair of large capacitors, and in front of the transformer. Now I’m looking for someone who can tell me what it might cost to repair it. I’m also curious about its power and capabilities, as there was no manual with it and nothing on it suggests its output rating.

The old electricity history facts 9090DB I’ve had since the late ‘70s, serial number 828050793, may have pot problems. The channels and controls are intermittent, sometimes working, sometimes not, and switching switches and turning knobs sometimes makes things work or quit working, especially in the Dolby area. The left channel is not working at all right now, but that could change next time it’s turned on. Even gas upper back pain the volume goes up and down by itself. I used to think the problem could be with the Bose active equalizer for my 901s, but after reading many of the posts in AK, it’s probably the receiver showing its age. As a military man (now retired) it has made its share of moves with us, although always packed in its original double carton. So, I’m also looking for the same thing for my 9090DB: someone to tell me what it will take to repair it, or suggest a home remedy gas constant mmhg if the problem truly could be simply dirty pots. I’m willing to try simple fixes, but would not want to start taking the thing apart, even with digital pictures for reassembly help.

I understand nobody is going to give me estimates sight unseen, but a SWAG would be appreciated. If the SWAG indicates I should go forward, I’m prepared to ship them to a shop if there isn’t one within driving distance. We live in eastern West Virginia and I work in Germantown, MD and Washington, DC, so someone close by these areas would be a plus. Thanks in advance for your advice and counsel.

Now that I’ve seen gas exchange in the lungs takes place in the the pics I can make some few comments. It appears to be a 4-gang FM tuner with at least 3 low GDT ceramic filters, the FM section is mid-class and not on the same league as the 8080DB/9090DB tuner section. The power amp uses an STK hybrid pre-driver which is not a good thing. These STKs are getting harder to find and I prefer totally dicrete power amp design like the 9090DBs. Part substitution is possible with discrete designs if you can’t find the original part#. The way the STK hybrid is mounted (freestanding) makes it prone to bad solder joints and this will lead to premature failure.

Back to your original problem with the protection light always on, this could be a simple trimpots adjustment, you are looking at 4 trimpots(2 for each channel) that needs to be adjusted. X-balanced amps are known to drift over grade 9 static electricity test time and go into protection mode when the output DC offset goes beyond acceptable limits. The repair cost might not be that high if no parts are broken. If you have a digital voltmeter and the service manual (go to www.obsinc.us, no affiliation with them just a return customer), you can fix z gas cd juarez it yourself. Service manual is $9.95 and a cheap DVM is ~$19.95. We have lots of techs on this forum who can guide you through the process.
