Just measured bias and adjusted offset on my 9090. I got the offset to ~15 mV on both channels. I didn't adjust the bias because it was no more than 10 mV on either channel.
 
There's an electrical hum that I can hear when the volume is all the way down. While trying to discover what the cause was, I found http://www.youtube.com/watch?v=ZnsFWx-zvzM&t=0m38s . I'm not sure if it's a capacitor issue but it definitely sounds like that. What can I do to find the source of the hum?

Remove the jumpers from the pre out to main in. Is it still there?
 
Try reversing the power plug, did that help?

Ok,I have satisfied my vintage receiver fix for the time being. 10 years ago I was a hardcore addict-of vintage audio-had 20+ receivers, 10+ sets of speakers, tape decks, reel to reel, etc.Sold it all but the 2 Marantz units when I divorced Satan's spawn.  Slowly getting the itch back again. Have the Marantz 2220B and 2270 and just acquired a Sherwood 7200 and 7100A. Man I love these Sherwoods. Very tube like.
 


 
 
Was detailing the 2270 last week and my wife says wow, it's really nice. What can you do with it?

You can place it in a doorway on breezy days to keep your door from slamming shut...

Anyone have any experience past or present with ITT stuff? I realize I may have to run an adapter here in Canada from the 220 unless it's switchable, but some of their stuff makes me drool.
  They are still around doing all sorts of stuff these days even, was eyeing up a couple of the vintage higher end receivers, silver of course.
 reminds me of a sort of grundig  company but bigger and better from what I can tell.
 
Thanks.

Hi Boys, Maybe sb can help me. I am looking for a decent faceplate from a Marantz 2325. Have fun Philipp

my roommate's dad is giving me a 35wpc fisher tube receiver for free...I tried to pay him for it, but he won't hear any of it. So instead I'm going to refoam his broken sony speakers for him...fingers crossed, this could be epic

 For that I would definitely do an eBay Saved Search.
