I picked up this Sansui 661 today for 30.00. Seemed a little high on the price but it is pretty clean inside and out and sounds good. Anyone have one of these?

I have one of these that I could never sort out.
The DC offset seems to jump all over the place and even though I have the manual it cannot be adjusted.
It played fine though.
FWIW I don't have the manual, but the 551 manual shows capacitor coupled (771 direct). If they have couling capacitors, there won't be an offset adjustment and dc should go to zero quickly with any load - speakers or headphones.
Crap! I've been trying to adjust it without any load.
Could this be the reason the voltage is jumping around? My friend owned it and it sounded fine. I only noticed this when I attempted to adjust the bias and offset.

Sorry for the misdirection. It is DC coupled. How much offset and how much jumping around? If too jumpy you may try cleaning potentiometer. If that works, you can leave it at that, but in my experience it has been best to replace it. If no difference, it usually is the differential pair (input) but usually noise or other problems. (Perhaps I'm over analyzing) Good luck with it.
You did fine! :thmbsp: It's 27 watts/ch and an average resale of $33 from eBay (people have paid up to $100) -- a very nice Sansui indeed.
I recently found one of those, mine was stamped "DEMO" on the back panel.
Great receiver, and yes the XX1 series are underappreciated, except the TOTL 881, which has gone up in price for very good examples on the auction site.
With efficient speakers you won't need megawattage anyway, and they are underated as all the vintage Sansui units were.
