Hello Sansui people. Long time lurker, first time poster. Hoping to get a clue to maybe save me a trip to my local technician. I've been a Sansui devotee for more decades than I care to mention. They're all over my house and driving my Sonos system. You could say I'm a big fan. My wife says I'm a nut.
Anyway...
Just picked up my first G-801. Wanted one of these monsters for a long time and finally just bit the bullet. Owner said the volume control would need to be cleaned. Otherwise this puppy is gorgeous inside and out.
I hooked it up in my workshop, checked all the controls and turned it on. I was getting almost no sound but after a couple minutes I was getting a little bit on all for speakers. Started wiggling the volume control and I would get the occasional burst of sound. Then I remembered the connected/separated switch. Shut it off, played with the switch, turned it back on and wonderful wonderfulness! Absolutely stunning! All the controls were noise free and the tuner worked great.
After about 1/2 hour I shut it down to take it upstairs to hook up in the living room. When I turned it on, I immediately noticed a small popping sound coming from the left speaker every second or so but irregularly. When the popping was there (which was most of the time) any source would be pretty badly distorted possibly just on the left. Volume control had no affect on popping noise. Source had no affect. None of the other controls seemed to make a difference. Played some more with the connected/separated switch with no difference. Bypassed the connected/separated switch with no difference.
Took it back downstairs. Opened it up. New Nichicon caps absolutely everywhere! Pulled the front and bottom and the boards to access the controls. Cleaned all controls with Deoxit 5 and the connected/separated switch with Deoxit 100. Also cleaned every pin plug that was reasonably accessible including the blackened ones. Hours later... I reassembled it enough to test it and no difference. AARRGGHH!! I was really hoping it was the switch but I'm pretty certain it's clean enough now to have made a difference especially since it was fine initially for about a half hour. Boy did it sound great. So aggravating to have lost it.
So, I'm guessing it's a problem on the amp side. I'm not very technical and I personally feel I suck at soldering (for a very long time now). I'm just good enough to be dangerous. I'm great at mechanical, hardware and furniture stuff.
Anyway, sorry for the long post, I tend to be very detail oriented and verbose. I'm just hoping to get some kind of a clue. One more thing worth noting; at one point, in the living room, I was unplugging an accessory while it was on and popping and the plug violently popped out sort of causing me to bang the back of the unit. When this happened, there were several pops all at once. Tried hitting it a little bit to recreate and nothing happened.
Looking forward to your replies and thank you.
Jeff
